sdm prefer

Use the sdm prefer global configuration command to configure the template used in Switch Database Management (SDM) resource allocation. You can use a template to allocate system resources to best support the features being used in your application. Use a template to provide maximum system usage for VLAN configuration or to select the dual IPv4 and IPv6 template to support IPv6 host. Use the no form of this command to return to the default template.

sdm prefer {access | default | dual-ipv4-and-ipv6 {default | vlan} | vlan}
no sdm prefer
Syntax Description

access

Provide maximum system usage for access control lists (ACLs). Use this template if you have a large number of ACLs.

default

Give balance to all functions.

dual-ipv4-and-ipv6 {default | vlan}

Select a template that supports both IPv4 and IPv6 functionality.

•default—Provide balance to IPv4 and IPv6 Layer 2 functionality.

•vlan—Provide maximum system usage for IPv4 and IPv6 VLANs.

vlan

Provide maximum system usage for VLANs.

Defaults

The default template provides a balance to all features.

Command Modes

Global configuration

Command History

Release

Modification

12.2(46)EY

This command was introduced.

Usage Guidelines

You must reload the switch for the configuration to take effect. If you enter the show sdm prefer command before you enter the reload privileged EXEC command, the show sdm prefer command shows the template currently in use and the template that will become active after a reload.

Use the no sdm prefer command to set the switch to the default template.

The access template maximizes system resources for access control lists (ACLs) as required to accommodate a large number of ACLs.

The default templates balances the use of system resources.

Do not use the ipv4-and-ipv6 templates if you do not plan to enable IPv6 on the switch. Entering the sdm prefer ipv4-and-ipv6 {default | vlan} global configuration command divides resources between IPv4 and IPv6, limiting those allocated to IPv4 forwarding.

Table 2-10 lists the approximate number of each resource that is supported in each of the IPv4-only templates for a switch. The values in the template are based on 8 routed interfaces and 1024 VLANs and represent the approximate hardware boundaries set when a template is selected. If a section of a hardware resource is full, all processing overflow is sent to the CPU, seriously impacting switch performance.

service password-recovery

Use the service password-recovery global configuration command to enable the password-recovery mechanism (the default). This mechanism allows an end user with physical access to the switch to hold down the Mode button and interrupt the boot process while the switch is powering up and to assign a new password. Use the no form of this command to disable part of the password-recovery functionality. When the password-recovery mechanism is disabled, interrupting the boot process is allowed only if the user agrees to set the system back to the default configuration.

service password-recovery
no service password-recovery
Syntax Description

This command has no arguments or keywords.

Defaults

The password-recovery mechanism is enabled.

Command Modes

Global configuration

Command History

Release

Modification

12.2(46)EY

This command was introduced.

Usage Guidelines

As a system administrator, you can use the no service password-recovery command to disable some of the functionality of the password recovery feature by allowing an end user to reset a password only by agreeing to return to the default configuration.

To use the password-recovery procedure, a user with physical access to the switch holds down the Mode button while the unit powers up and for a second or two after the LED above port 1X turns off. When the button is released, the system continues with initialization.

If the password-recovery mechanism is disabled, this message appears:
The password-recovery mechanism has been triggered, but
is currently disabled.  Access to the boot loader prompt
through the password-recovery mechanism is disallowed at
this point.  However, if you agree to let the system be
reset back to the default system configuration, access
to the boot loader prompt can still be allowed.
Would you like to reset the system back to the default configuration (y/n)?
If the user chooses not to reset the system to the default configuration, the normal boot process continues, as if the Mode button had not been pressed. If you choose to reset the system to the default configuration, the configuration file in flash memory is deleted, and the VLAN database file, flash:vlan.dat (if present), is deleted.

Note If you use the no service password-recovery command to control end user access to passwords, we recommend that you save a copy of the config file in a location away from the switch in case the end user uses the password recovery procedure and sets the system back to default values. Do not keep a backup copy of the config file on the switch.

If the switch is operating in VTP transparent mode, we recommend that you also save a copy of the vlan.dat file in a location away from the switch.

You can verify if password recovery is enabled or disabled by entering the show version privileged EXEC command.

Examples

This example shows how to disable password recovery so that a user can only reset a password by agreeing to return to the default configuration.
Switch(config)# no service-password recovery
Switch(config)# exit

Description

show version

Displays version information for the hardware and firmware.

service-policy

Use the service-policy interface configuration command to apply a policy map defined by the policy-map command to the input of a physical port or a switch virtual interface (SVI). Use the no form of this command to remove the policy map and port association.

service-policy input policy-map-name
no service-policy input policy-map-name

Note Though visible in the command-line help strings, the output keyword is not supported.

Syntax Description

input policy-map-name

Apply the specified policy map to the input of a physical port or an SVI.

Defaults

No policy maps are attached to the port.

Command Modes

Interface configuration

Command History

Release

Modification

12.2(46)EY

This command was introduced.

Usage Guidelines

Only one policy map per ingress port is supported.

Policy maps can be configured on physical ports or on SVIs. When VLAN-based quality of service (QoS) is disabled by using the no mls qos vlan-based interface configuration command on a physical port, you can configure a port-based policy map on the port. If VLAN-based QoS is enabled by using the mls qos vlan-based interface configuration command on a physical port, the switch removes the previously configured port-based policy map. After a hierarchical policy map is configured and applied on an SVI, the interface-level policy map takes effect on the interface.

You can apply a policy map to incoming traffic on a physical port or on an SVI. You can configure different interface-level policy maps for each class defined in the VLAN-level policy map. For more information about hierarchical policy maps, see the "Configuring QoS" chapter in the software configuration guide for this release.

Classification using a port trust state (for example, mls qos trust [cos | dscp | ip-precedence] and a policy map (for example, service-policy input policy-map-name) are mutually exclusive. The last one configured overwrites the previous configuration.

Examples

This example shows how to apply plcmap1 to an physical ingress port:
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# service-policy input plcmap1
This example shows how to remove plcmap2 from a physical port:
Switch(config)# interface gigabitethernet0/2
Switch(config-if)# no service-policy input plcmap2
This example shows how to apply plcmap1 to an ingress SVI when VLAN-based QoS is enabled:
Switch(config)# interface vlan 10
Switch(config-if)# service-policy input plcmap1
This example shows how to create a hierarchical policy map and attach it to an SVI:

no set {[ip] dscp new-dscp | [ip] precedence new-precedence}
Syntax Description

[ip] dscp new-dscp

New DSCP value assigned to the classified traffic. The range is 0 to 63. You also can enter a mnemonic name for a commonly used value.

[ip] precedence new-precedence

New IP-precedence value assigned to the classified traffic. The range is 0 to 7. You also can enter a mnemonic name for a commonly used value.

Defaults

No traffic classification is defined.

Command Modes

Command History

Release

Modification

12.2(46)EY

This command was introduced.

Usage Guidelines

If you have used the set ip dscp policy-map class configuration command, the switch changes this command to set dscp in the switch configuration. If you enter the set ip dscp policy-map class configuration command, this setting appears as set dscp in the switch configuration.

You can use the set ip precedence policy-map class configuration command or the set precedence policy-map class configuration command. This setting appears as set ip precedence in the switch configuration.

The set command is mutually exclusive with the trust policy-map class configuration command within the same policy map.

For the set dscp new-dscp or the set ip precedence new-precedence command, you can enter a mnemonic name for a commonly used value. For example, you can enter the set dscp af11 command, which is the same as entering the set dscp 10 command. You can enter the set ip precedence critical command, which is the same as entering the set ip precedence 5 command. For a list of supported mnemonics, enter the set dscp ? or the set ip precedence ? command to see the command-line help strings.

To return to policy-map configuration mode, use the exit command. To return to privileged EXEC mode, use the end command.

Examples

This example shows how to assign DSCP 10 to all FTP traffic without any policers:
Switch(config)# policy-map policy_ftp
Switch(config-pmap)# class ftp_class
Switch(config-pmap-c)# set dscp 10
Switch(config-pmap)# exit
You can verify your settings by entering the show policy-map privileged EXEC command.

Syntax Description

This command has no arguments or keywords.

Defaults

Express Setup is enabled.

Command Modes

Global configuration

Command History

Release

Modification

12.2(46)EY

This command was introduced.

Usage Guidelines

When Express Setup is enabled on a new (unconfigured) switch, pressing the Mode button for 2 seconds activates Express Setup. You can access the switch through an Ethernet port by using the IP address 10.0.0.1 and then can configure the switch with the web-based Express Setup program or the command-line interface (CLI)-based setup program.

When you press the Mode button for 2 seconds on a configured switch, the LEDs above the Mode button start blinking. If you press the Mode button for a total of 10 seconds, the switch configuration is deleted, and the switch reboots. The switch can then be configured like a new switch, either through the web-based Express Setup program or the CLI-based setup program.

Note As soon as you make any change to the switch configuration (including entering no at the beginning of the CLI-based setup program), configuration by Express Setup is no longer available. You can only run Express Setup again by pressing the Mode button for 10 seconds. This deletes the switch configuration and reboots the switch.

If Express Setup is active on the switch, entering the write memory or copy running-configuration startup-configuration privileged EXEC commands deactivates Express Setup. The IP address 10.0.0.1 is no longer valid on the switch, and your connection using this IP address ends.

The primary purpose of the no setup express command is to prevent someone from deleting the switch configuration by pressing the Mode button for 10 seconds.

Examples

This example shows how to enable Express Setup mode:
Switch(config)# setup express
You can verify that Express Setup mode is enabled by pressing the Mode button:

•On an unconfigured switch, the LEDs above the Mode button turn solid green after 3 seconds.

•On a configured switch, the mode LEDs begin blinking after 2 seconds and turn solid green after 10 seconds.

Caution If you hold the Mode button down for a total of 10 seconds, the configuration is deleted, and the switch reboots.

This example shows how to disable Express Setup mode:
Switch(config)# no setup express
You can verify that Express Setup mode is disabled by pressing the Mode button. The mode LEDs do not turn solid green or begin blinking green if Express Setup mode is not enabled on the switch.

Field

Description

BOOT path-list

Displays a semicolon separated list of executable files to try to load and execute when automatically booting.

If the BOOT environment variable is not set, the system attempts to load and execute the first executable image it can find by using a recursive, depth-first search through the flash file system. In a depth-first search of a directory, each encountered subdirectory is completely searched before continuing the search in the original directory.

If the BOOT variable is set but the specified images cannot be loaded, the system attempts to boot the first bootable file that it can find in the flash file system.

Config file

Displays the filename that Cisco IOS uses to read and write a nonvolatile copy of the system configuration.

Private Config file

Displays the filename that Cisco IOS uses to read and write a nonvolatile copy of the system configuration.

Enable Break

Displays whether a break during booting is enabled or disabled. If it is set to yes, on, or 1, you can interrupt the automatic boot process by pressing the Break key on the console after the flash file system is initialized.

Manual Boot

Displays whether the switch automatically or manually boots. If it is set to no or 0, the boot loader attempts to automatically boot up the system. If it is set to anything else, you must manually boot up the switch from the boot loader mode.

Helper path-list

Displays a semicolon separated list of loadable files to dynamically load during the boot loader initialization. Helper files extend or patch the functionality of the boot loader.

This command was introduced.

Usage Guidelines

This command is available only on the cluster command switch.

If the switch is not a cluster command switch, the command displays an empty line at the prompt.

The SN in the display means switch member number. If E appears in the SN column, it means that the switch is discovered through extended discovery. If E does not appear in the SN column, it means that the switch member number is the upstream neighbor of the candidate switch. The hop count is the number of devices the candidate is from the cluster command switch.

Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output are not displayed, but the lines that contain Output are displayed.

Examples

This is an example of output from the show cluster candidates command:

Usage Guidelines

Use the show ip igmp snooping querier command to display the IGMP version and the IP address of a detected device, also called a querier, that sends IGMP query messages. A subnet can have multiple multicast routers but has only one IGMP querier. In a subnet running IGMPv2, one of the multicast routers is elected as the querier. The querier can be a Layer 3 switch.

The show ip igmp snooping querier command output also shows the VLAN and the interface on which the querier was detected. If the querier is the switch, the output shows the Port field as Router. If the querier is a router, the output shows the port number on which the querier is learned in the Port field.

The show ip igmp snooping querier detail user EXEC command is similar to the show ip igmp snooping querier command. However, the show ip igmp snooping querier command displays only the device IP address most recently detected by the switch querier.

The show ip igmp snooping querier detail command displays the device IP address most recently detected by the switch querier and this additional information:

•The elected IGMP querier in the VLAN

•The configuration and operational information pertaining to the switch querier (if any) that is configured in the VLAN

Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output do not appear, but the lines that contain Output appear.

Usage Guidelines

Use the show ipv6 mld snooping querier command to display the MLD version and IPv6 address of a detected device that sends MLD query messages, which is also called a querier. A subnet can have multiple multicast routers but has only one MLD querier. The querier can be a Layer 3 switch.

The show ipv6 mld snooping querier command output also shows the VLAN and interface on which the querier was detected. If the querier is the switch, the output shows the Port field as Router. If the querier is a router, the output shows the port number on which the querier is learned in the Port field.

The output of the show ipv6 mld snoop querier vlan command displays the information received in response to a query message from an external or internal querier. It does not display user-configured VLAN values, such as the snooping robustness variable on the particular VLAN. This querier information is used only on the MASQ message that is sent by the switch. It does not override the user-configured robustness variable that is used for aging out a member that does not respond to query messages.

VLAN numbers 1002 through 1005 are reserved for Token Ring and FDDI VLANs and cannot be used in MLD snooping.

To configure the dual IPv4 and IPv6 template, enter the sdm prefer dual-ipv4-and-ipv6 {default | vlan} global configuration command and reload the switch.

Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output do not appear, but the lines that contain Output appear.

Field

Description

State

State of the specific port. These are the allowed values:

•- —Port is in an unknown state.

•bndl—Port is attached to an aggregator and bundled with other ports.

•susp—Port is in a suspended state; it is not attached to any aggregator.

•hot-sby—Port is in a hot-standby state.

•indiv—Port is incapable of bundling with any other port.

•indep—Port is in an independent state (not bundled but able to switch data traffic. In this case, LACP is not running on the partner port).

•down—Port is down.

LACP Port Priority

Port priority setting. LACP uses the port priority to put ports s in standby mode when there is a hardware limitation that prevents all compatible ports from aggregating.

Admin Key

Administrative key assigned to this port. LACP automatically generates an administrative key value as a hexadecimal number. The administrative key defines the ability of a port to aggregate with other ports. A port's ability to aggregate with other ports is determined by the port physical characteristics (for example, data rate and duplex capability) and configuration restrictions that you establish.

Oper Key

Runtime operational key that is being used by this port. LACP automatically generates this value as a hexadecimal number.

Port Number

Port number.

Port State

State variables for the port, encoded as individual bits within a single octet with these meanings:

•bit0: LACP_Activity

•bit1: LACP_Timeout

•bit2: Aggregation

•bit3: Synchronization

•bit4: Collecting

•bit5: Distributing

•bit6: Defaulted

•bit7: Expired

Note In the list above, bit7 is the MSB and bit0 is the LSB.

show mls qos maps

Use the show mls qos maps user EXEC command to display quality of service (QoS) mapping information. During classification, QoS uses the mapping tables to represent the priority of the traffic and to derive a corresponding class of service (CoS) or Differentiated Services Code Point (DSCP) value from the received CoS, DSCP, or IP precedence value.

show mls qos maps [cos-dscp | cos-input-q | cos-output-q | dscp-cos | dscp-input-q | dscp-mutation dscp-mutation-name | dscp-output-q | ip-prec-dscp | policed-dscp] [ | {begin | exclude | include} expression]
Syntax Description

Usage Guidelines

Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output do not appear, but the lines that contain Output appear.

The policed-DSCP, DSCP-to-CoS, and the DSCP-to-DSCP-mutation maps appear as a matrix. The d1 column specifies the most-significant digit in the DSCP. The d2 row specifies the least-significant digit in the DSCP. The intersection of the d1 and d2 values provides the policed-DSCP, the CoS, or the mutated-DSCP value. For example, in the DSCP-to-CoS map, a DSCP value of 43 corresponds to a CoS value of 5.

The DSCP input queue threshold and the DSCP output queue threshold maps appear as a matrix. The d1 column specifies the most-significant digit of the DSCP number. The d2 row specifies the least-significant digit in the DSCP number. The intersection of the d1 and the d2 values provides the queue ID and threshold ID. For example, in the DSCP input queue threshold map, a DSCP value of 43 corresponds to queue 2 and threshold 1 (02-01).

The CoS input queue threshold and the CoS output queue threshold maps show the CoS value in the top row and the corresponding queue ID and threshold ID in the second row. For example, in the CoS input queue threshold map, a CoS value of 5 corresponds to queue 2 and threshold 1 (2-1).

Usage Guidelines

When you change the SDM template by using the sdm prefer global configuration command, you must reload the switch for the configuration to take effect. If you enter the show sdm prefer command before you enter the reload privileged EXEC command, the show sdm prefer command shows the template currently in use and the template that will become active after a reload.

The numbers displayed for each template represent an approximate maximum number for each feature resource. The actual number might vary, depending on the actual number of other features configured.

Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output do not appear, but the lines that contain Output appear.

Examples

Note The switch supports only 128 VLANs, although the output in the examples and on the switch refers to 1024 VLANs.

This is an example of output from the show sdm prefer command:
Switch# show sdm prefer
 The current template is "desktop default" template.

Table 2-21 show udld Field Descriptions

Field

Description

Interface

The interface on the local device configured for UDLD.

Port enable administrative configuration setting

How UDLD is configured on the port. If UDLD is enabled or disabled, the port enable configuration setting is the same as the operational enable state. Otherwise, the enable operational setting depends on the global enable setting.

Port enable operational state

Operational state that shows whether UDLD is actually running on this port.

Current bidirectional state

The bidirectional state of the link. An unknown state appears if the link is down or if it is connected to an UDLD-incapable device. A bidirectional state appears if the link is a normal two-way connection to a UDLD-capable device. All other values mean miswiring.

Current operational state

The current phase of the UDLD state machine. For a normal bidirectional link, the state machine is most often in the Advertisement phase.

Message interval

How often advertisement messages are sent from the local device. Measured in seconds.

Time out interval

The time period, in seconds, that UDLD waits for echoes from a neighbor device during the detection window.

Entry 1

Information from the first cache entry, which contains a copy of echo information received from the neighbor.

Expiration time

The amount of time in seconds remaining before this cache entry is aged out.

Device ID

The neighbor device identification.

Current neighbor state

The neighbor's current state. If both the local and neighbor devices are running UDLD normally, the neighbor state and local state should be bidirectional. If the link is down or the neighbor is not UDLD-capable, no cache entries appear.

Device name

The device name or the system serial number of the neighbor. The system serial number appears if the device name is not set or is set to the default (Switch).

Port ID

The neighbor port ID enabled for UDLD.

Neighbor echo 1 device

The device name of the neighbors' neighbor from which the echo originated.

Neighbor echo 1 port

The port number ID of the neighbor from which the echo originated.

Message interval

The rate, in seconds, at which the neighbor is sending advertisement messages.

CDP device name

The CDP device name or the system serial number. The system serial number appears if the device name is not set or is set to the default (Switch).

Usage Guidelines

In the show vlan mtu command output, the MTU_Mismatch column shows whether all the ports in the VLAN have the same MTU. When yes appears in this column, it means that the VLAN has ports with different MTUs, and packets that are switched from a port with a larger MTU to a port with a smaller MTU might be dropped. If the VLAN does not have an SVI, the hyphen (-) symbol appears in the SVI_MTU column. If the MTU-Mismatch column displays yes, the names of the port with the MinMTU and the port with the MaxMTU appear.

Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output do not appear, but the lines that contain Output appear.

Description

Summary advertisements received

Number of summary advertisements received by this switch on its trunk ports. Summary advertisements contain the management domain name, the configuration revision number, the update timestamp and identity, the authentication checksum, and the number of subset advertisements to follow.

Subset advertisements received

Number of subset advertisements received by this switch on its trunk ports. Subset advertisements contain all the information for one or more VLANs.

Request advertisements received

Number of advertisement requests received by this switch on its trunk ports. Advertisement requests normally request information on all VLANs. They can also request information on a subset of VLANs.

Summary advertisements transmitted

Number of summary advertisements sent by this switch on its trunk ports. Summary advertisements contain the management domain name, the configuration revision number, the update timestamp and identity, the authentication checksum, and the number of subset advertisements to follow.

Subset advertisements transmitted

Number of subset advertisements sent by this switch on its trunk ports. Subset advertisements contain all the information for one or more VLANs.

Request advertisements transmitted

Number of advertisement requests sent by this switch on its trunk ports. Advertisement requests normally request information on all VLANs. They can also request information on a subset of VLANs.

Number of configuration revision errors

Number of revision errors.

Whenever you define a new VLAN, delete an existing one, suspend or resume an existing VLAN, or modify the parameters on an existing VLAN, the configuration revision number of the switch increments.

Revision errors increment whenever the switch receives an advertisement whose revision number matches the revision number of the switch, but the MD5 digest values do not match. This error means that the VTP password in the two switches is different or that the switches have different configurations.

These errors means that the switch is filtering incoming advertisements, which causes the VTP database to become unsynchronized across the network.

Number of configuration digest errors

Number of MD5 digest errors.

Digest errors increment whenever the MD5 digest in the summary packet and the MD5 digest of the received advertisement calculated by the switch do not match. This error usually means that the VTP password in the two switches is different. To solve this problem, make sure the VTP password on all switches is the same.

These errors mean that the switch is filtering incoming advertisements, which causes the VTP database to become unsynchronized across the network.

Number of V1 summary errors

Number of Version 1 errors.

Version 1 summary errors increment whenever a switch in VTP V2 mode receives a VTP Version 1 frame. These errors mean that at least one neighboring switch is either running VTP Version 1 or VTP Version 2 with V2-mode disabled. To solve this problem, change the configuration of the switches in VTP V2-mode to disabled.

Join Transmitted

Number of VTP pruning messages sent on the trunk.

Join Received

Number of VTP pruning messages received on the trunk.

Summary Advts Received from non-pruning-capable device

Number of VTP summary messages received on the trunk from devices that do not support pruning.

This is an example of output from the show vtp status command. Table 2-24 describes each field in the display.

Field

Description

VTP Version

Displays the VTP version operating on the switch. By default, the switch implements Version 1 but can be set to Version 2.

Configuration Revision

Current configuration revision number on this switch.

Maximum VLANs Supported Locally

Maximum number of VLANs supported locally.

Number of Existing VLANs

Number of existing VLANs.

VTP Operating Mode

Displays the VTP operating mode, which can be server, client, or transparent.

Server: a switch in VTP server mode is enabled for VTP and sends advertisements. You can configure VLANs on it. The switch guarantees that it can recover all the VLAN information in the current VTP database from NVRAM after reboot. By default, every switch is a VTP server.

Note The switch automatically changes from VTP server mode to VTP client mode if it detects a failure while writing the configuration to NVRAM and cannot return to server mode until the NVRAM is functioning.

Client: a switch in VTP client mode is enabled for VTP, can send advertisements, but does not have enough nonvolatile storage to store VLAN configurations. You cannot configure VLANs on it. When a VTP client starts up, it does not send VTP advertisements until it receives advertisements to initialize its VLAN database.

Transparent: a switch in VTP transparent mode is disabled for VTP, does not send or learn from advertisements sent by other devices, and cannot affect VLAN configurations on other devices in the network. The switch receives VTP advertisements and forwards them on all trunk ports except the one on which the advertisement was received.

VTP Domain Name

Name that identifies the administrative domain for the switch.

VTP Pruning Mode

Displays whether pruning is enabled or disabled. Enabling pruning on a VTP server enables pruning for the entire management domain. Pruning restricts flooded traffic to those trunk links that the traffic must use to access the appropriate network devices.

VTP V2 Mode

Displays if VTP Version 2 mode is enabled. All VTP Version 2 switches operate in Version 1 mode by default. Each VTP switch automatically detects the capabilities of all the other VTP devices. A network of VTP devices should be configured to Version 2 only if all VTP switches in the network can operate in Version 2 mode.

VTP Traps Generation

Displays whether VTP traps are sent to a network management station.

MD5 Digest

A 16-byte checksum of the VTP configuration.

Configuration Last Modified

Displays the date and time of the last configuration modification. Displays the IP address of the switch that caused the configuration change to the database.
