Usage Guidelines
The RMON statistics collection command is based on hardware counters. If the port is a user network interface (UNI) or enhanced network interface (ENI), you must use the no shutdown interface configuration command to enable it before using the rmon collection stats command. UNIs and ENIs are disabled by default. Network node interfaces (NNIs) are enabled by default.
Examples
This example shows how to collect RMON statistics for the owner root:
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# rmon collection stats 2 owner root
You can verify your setting by entering the show rmon statistics privileged EXEC command.

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 press the break key on the console terminal to 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.

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. This provides configuration file security by ensuring that only authenticated and authorized users have access to the configuration file and prevents users from accessing the configuration file by using the password recovery process.
The password recovery procedure requires using a break key. After the switch performs power-on self test (POST), the switch begins the autoboot process. The boot loader prompts the user for a break key character during the boot-up sequence, as shown in this example:
***** The system will autoboot in 5 seconds *****
Send a break key to prevent autobooting.
You must enter the break key on the console terminal within 5 seconds of receiving the message that the system will autoboot. A user with physical access to the switch presses the break key on the console terminal within 5 seconds of receiving the message that flash memory is initializing. The System LED flashes green until the break key is accepted. After the break key is accepted, the System LED turns off until after the switch boots.
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 break key 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 configuration 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 configuration file on the switch.
You can enter the show version privileged EXEC command to determine if password recovery is enabled or disabled.
Examples
This example shows how to disable password recovery on a switch so that a user can only reset a password by agreeing to return to the default configuration.
Switch(config)# no service-password recovery

Usage Guidelines
Only one input policy map and one output policy map can be attached to an interface.
Beginning with Cisco IOS Release 12.2(35)SE, you can attach an output policy map to each interface on the switch. However, the switch supports a limit of three unique queue-limit configurations across all output policy maps at any time. Multiple policy maps can share the same queue-limit configuration.If you try to attach an output policy map with a fourth unique queue-limit configuration, you see this error message:
QoS: Configuration failed. Maximum number of allowable unique queue-limit
configurations exceeded.
You can attach input or output policy maps to a Fast Ethernet or Gigabit Ethernet port. You cannot attach policy maps to switch virtual interfaces (SVIs) and EtherChannel interfaces.
Examples
This example shows how to apply plcmap1 as an output policy map:
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# service-policy output plcmap1
This example shows how to remove plcmap2 from the port:
Switch(config)# interface gigabitethernet0/2
Switch(config-if)# no service-policy output plcmap2
You can verify your settings by entering the show running-config privileged EXEC command.

Usage Guidelines
You attach a service policy created in policy-map class configuration to a parent output policy map. This creates hierarchical policy mapping. Use the service-policy policy-map-name policy-map class configuration command to enter a second-level (child) policy map.
For an output policy map, when shape average is also configured on the class class-default, you can configure hierarchical policy maps by attaching a single service-policy policy-map class command to the class class-default. This policy map specifies the service policy for the port-shaped traffic on the port and is the parent policy map. You can configure the child policy with class-based queuing actions by using the queue-limit policy map class command and with scheduling actions (by using the bandwidth, shape average, or priority command).
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 define the service policy and to attach it to a parent policy map to set the maximum bandwidth (shape) for an output queue at 90000000 bits per second:
Switch(config)# policy-map out-policy-parent
Switch(config-pmap)# class class-default
Switch(config-pmap-c)# shape average 90000000
Switch(config-pmap-c)# service-policy out-policy
Switch(config-pmap-c)# exit
Switch(config-pmap)# exit
You can verify your settings by entering the show policy-map privileged EXEC command.

Support was added to set multiple marking actions and to use table maps for enhanced packet marking. See "Usage Guidelines."
|
Usage Guidelines
Beginning with Cisco IOS Release 12.2(25)SEG, you can configure set cos with all other marking actions, specifically set dscp, set precedence, and set qos-group, for the same class. Support was also added for the ability to configure more than one marking action with enhanced packet marking by using table maps for the same class.
Use the set cos command if you want to mark a packet that is being sent to a switch. Switches can leverage Layer 2 header information including a CoS value marking.
You can use the match cos class-map configuration command and the set cos policy-map class configuration command together to allow switches to interoperate and provide quality of service (QoS) based on the CoS markings. You can also configure Layer 2 to Layer 3 mapping by matching on the CoS value because switches can already match and set CoS values.
If you are using this command to perform enhanced packet marking, you can use the from-field packet marking option for mapping and setting the CoS value. The supported from-field marking categories are: CoS, DSCP, and IP precedence.
If you specify a from-field category, but do not specify the table keyword and table-map-name, the default action is to copy the value associated with the from-field category as the CoS value. For example, if you enter the set cos precedence command, the precedence value is copied and used as the CoS value. If you enter the set cos dscp command, the DSCP value is copied and used as the CoS value.
Examples
This example shows how to set all FTP traffic to cos 3:
Switch(config)# policy-map policy_ftp
Switch(config-pmap)# class ftp_class
Switch(config-pmap-c)# set cos 3
Switch(config-pmap-c)# exit
This example shows how to assign a DSCP to CoS table map to a class:
Switch(config)# policy-map inpolicy
Switch(config-pmap)# class class-default
Switch(config-pmap-c)# set cos dscp table dscp-cos-tablemap
Switch(config-pmap)# exit
You can verify your settings by entering the show policy-map privileged EXEC command.

Usage Guidelines
Beginning with Cisco IOS Release 12.2(25)SEG, you can configure set dscp with other marking actions, specifically set cos and set qos-group, for the same class. Support was also added for the ability to configure more than one marking action with enhanced packet marking by using table maps for the same class.
You cannot use the set dscp command with the set precedence command to mark the same packet. DSCP values and IP precedence values are mutually exclusive. A packet can have one value of the other, but not both.
After DSCP bits are set, other quality of service (QoS) features can then operate on the bit settings.
The network gives priority (or some type of expedited handling) to marked traffic. Typically, you set the DSCP value at the edge of the network (or administrative domain) and data is then queued according to the precedence. Class-based weighted fair queuing (CBWFQ) can speed up handling for high-precedence traffic at congestion points. Weighted Tail Drop (WTD) ensures that high-precedence traffic has lower loss rates than other traffic during times of congestion.
Instead of using numeric values, you can also specify the dscp-value by using the reserved keywords EF, AF11, and AF12.
If you are using this command to perform enhanced packet marking, you can use the from-field packet marking option for mapping and setting the DSCP value. The supported from-field marking categories are: CoS, DSCP, and IP precedence.
If you specify a from-field category, but do not specify the table keyword and table-map-name, the default action is to copy the value associated with the from-field category as the DSCP value. For example, if you enter the set dscp cos command, the CoS value is copied and used as the DSCP value.
Examples
This example shows how to set all FTP traffic to DSCP 10:
Switch(config)# policy-map policy_ftp
Switch(config-pmap)# class ftp_class
Switch(config-pmap-c)# set dscp 10
Switch(config-pmap-c)# exit
This example shows how to assign a CoS to DSCP table map to a class:
Switch(config)# policy-map inpolicy
Switch(config-pmap)# class class-default
Switch(config-pmap-c)# set dscp cos table cos-dscp-tablemap
Switch(config-pmap)# exit

Configuring traffic shaping for a user-defined class or class-default for class-based shaping sets the peak information rate (PIR) for that class. Configuring traffic shaping for the class class-default when it is the only class in the policy map that is attached to an interface sets the PIR for the interface (port shaping).
You cannot configure shape average in a class that includes priority queueing (configured with the priority policy-map class configuration command).
The shape average command uses a default queue limit for the class. You can change the queue limit by using the queue-limit policy-map class command, overriding the default that is set by the shape average command.
You cannot use the bandwidth policy-map class configuration command to configure class-based weighted fair queuing (CBWFQ) and the shape average command to configure traffic shaping for the same class.
You can configure hierarchical policy maps by attaching the service-policy policy-map class command to the class class-default only when shape average is also configured on the class class-default.
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 configure traffic shaping for outgoing traffic on a Fast Ethernet port so that outclass1, outclass2, and outclass3 get a maximum of 50, 20, and 10 Mbps of the buffer size. The class class-default gets the remaining bandwidth.
Switch(config)# policy-map out-policy
Switch(config-pmap)# class classout1
Switch(config-pmap-c)# shape average 50000000
Switch(config-pmap-c)# exit
Switch(config-pmap)# class classout2
Switch(config-pmap-c)# shape average 20000000
Switch(config-pmap-c)# exit
Switch(config-pmap)# class classout3
Switch(config-pmap-c)# shape average 10000000
Switch(config-pmap-c)# exit
Switch(config-pmap)# exit
Switch(config)# interface fastethernet 0/1
Switch(config-if)# service-policy out out-policy
This example shows how to configure port shaping by configuring a hierarchical policy map that shapes a port to 90 Mbps, allocated according to the out-policy policy map configured in the previous example.
Switch(config)# policy-map out-policy-parent
Switch(config-pmap)# class class-default
Switch(config-pmap-c)# shape average 90000000
Switch(config-pmap-c)# service-policy out-policy
Switch(config-pmap-c)# exit
Switch(config-pmap)# exit
You can verify your settings by entering the show policy-map privileged EXEC command.

Usage Guidelines
The command is case sensitive. With no arguments, the show inventory command produces a compact display of all identifiable entities that have a product identifier. The display shows the entity location (slot identity), entity description, and the unique device identifier (UDI), including PID, version identifier (VID), and serial number (SN) of that entity.
Many legacy SFPs are not programmed with PIDs and VID.s
Note
If there is no PID, no output appears when you enter the show inventory command.
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.

Table 2-12 DHCP Snooping Statistics
DHCP Snooping Statistic
|
Description
|
Packets Processed by DHCP Snooping
|
Total number of packets handled by DHCP snooping, including forwarded and dropped packets.
|
Packets Dropped Because IDB not known
|
Number of errors when the input interface of the packet cannot be determined.
|
Queue full
|
Number of errors when an internal queue used to process the packets is full. This might happen if DHCP packets are received at an excessively high rate and rate limiting is not enabled on the ingress ports.
|
Interface is in errdisabled
|
Number of times a packet was received on a port that has been marked as error disabled. This might happen if packets are in the processing queue when a port is put into the error-disabled state and those packets are subsequently processed.
|
Rate limit exceeded
|
Number of times the rate limit configured on the port was exceeded and the interface was put into the error-disabled state.
|
Received on untrusted ports
|
Number of times a DHCP server packet (OFFER, ACK, NAK, or LEASEQUERY) was received on an untrusted port and was dropped.
|
Nonzero giaddr
|
Number of times the relay agent address field (giaddr) in the DHCP packet received on an untrusted port was not zero, or the no ip dhcp snooping information option allow-untrusted global configuration command is not configured and a packet received on an untrusted port contained option-82 data.
|
Source mac not equal to chaddr
|
Number of times the client MAC address field of the DHCP packet (chaddr) does not match the packet source MAC address and the ip dhcp snooping verify mac-address global configuration command is configured.
|
Binding mismatch
|
Number of times a RELEASE or DECLINE packet was received on a port that is different than the port in the binding for that MAC address-VLAN pair. This indicates someone might be trying to spoof the real client, or it could mean that the client has moved to another port on the switch and issued a RELEASE or DECLINE. The MAC address is taken from the chaddr field of the DHCP packet, not the source MAC address in the Ethernet header.
|
Insertion of opt82 fail
|
Number of times the option-82 insertion into a packet failed. The insertion might fail if the packet with the option-82 data exceeds the size of a single physical packet on the internet.
|
Interface Down
|
Number of times the packet is a reply to the DHCP relay agent, but the SVI interface for the relay agent is down. This is an unlikely error that occurs if the SVI goes down between sending the client request to the DHCP server and receiving the response.
|
Unknown output interface
|
Number of times the output interface for a DHCP reply packet cannot be determined by either option-82 data or a lookup in the MAC address table. The packet is dropped. This can happen if option 82 is not used and the client MAC address has aged out. If IPSG is enabled with the port-security option and option 82 is not enabled, the MAC address of the client is not learned, and the reply packets will be dropped.
|
Reply output port equal to input port
|
Number of times the output port for a DHCP reply packet is the same as the input port, causing a possible loop. Indicates a possible network misconfiguration or misuse of trust settings on ports.
|
Packet denied by platform
|
Number of times the packet has been denied by a platform-specific registry.

Usage Guidelines
Use the show ip igmp snooping querier command to display the IGMP version and IP address of a detected device (also called a querier) that sends IGMP query message. 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 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 detail command displays the IP address of the most recent device detected by the switch querier along with this additional information:
•

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

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.
Examples
This is an example of output from the show mvr command:
MVR Max Multicast Groups: 256
MVR Current multicast groups: 0
MVR Global query response time: 5 (tenths of sec)
In the preceding display, the maximum number of multicast groups is fixed at 256. The MVR mode is either compatible (for interoperability with Catalyst 2900 XL and Catalyst 3500 XL switches) or dynamic (where operation is consistent with IGMP snooping operation and dynamic MVR membership on source ports is supported).

Usage Guidelines
If the entered port identification is a non-MVR port or a source port, the command returns an error message. For receiver ports, it displays the port type, per port status, and Immediate-Leave setting.
If you enter the show mvr interface interface-id command and the specified port is a non-MVR port, the output displays NON MVR in the Type field. For active MVR ports, it displays the port type (RECEIVER or SOURCE), mode (access or trunk), VLAN, status, and Immediate-Leave setting.
If you enter the members keyword, all MVR group members on the interface 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.
Examples
This is an example of output from the show mvr interface command:
Switch# show mvr interface

Table 2-17 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. 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 a switch virtual interface (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.
If you try to associate a private VLAN secondary VLAN with a primary VLAN before you define the secondary VLAN, the secondary VLAN is not included in the show vlan private-vlan command output.
In the show vlan private-vlan type command output, a normal type means a VLAN has a private VLAN association but is not part of the private VLAN. For example, if you define and associate two VLANs as primary and secondary VLANs and then delete the secondary VLAN configuration but do not remove the association from the primary VLAN, the VLAN that was the secondary VLAN is shown as normal in the display. In the show vlan private-vlan output, the primary and secondary VLAN pair is shown as non-operational.
In the show vlan uni-vlan type command output, type is either community or isolated. User network interfaces (UNIs) or enhanced network interfaced (ENIs) in a UNI-ENI community VLAN can communicate with each other; UNIs or ENIs in a UNI-ENI isolated VLAN cannot communicate. Network node interfaces (NNIs) can communicate with each other and with UNIs or ENIs in UNI-ENI isolated and community VLANs.
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
This is an example of output from the show vlan command. Table 2-18 describes the fields in the display.
Note
The switch supports only Ethernet VLANs. You can configure parameters for FDDI and Token Ring VLANs and view the results in the vlan.dat file, but these parameters are not supported or used.

Table 2-19 show vmps statistics Field Descriptions
Field
|
Description
|
VQP Queries
|
Number of queries sent by the client to the VMPS.
|
VQP Responses
|
Number of responses sent to the client from the VMPS.
|
VMPS Changes
|
Number of times that the VMPS changed from one server to another.
|
VQP Shutdowns
|
Number of times the VMPS sent a response to shut down the port. The client disables the port and removes all dynamic addresses on this port from the address table. You must administratively re-enable the port to restore connectivity.
|
VQP Denied
|
Number of times the VMPS denied the client request for security reasons. When the VMPS response denies an address, no frame is forwarded to or from the workstation with that address (broadcast or multicast frames are delivered to the workstation if the port has been assigned to a VLAN). The client keeps the denied address in the address table as a blocked address to prevent more queries from being sent to the VMPS for each new packet received from this workstation. The client ages the address if no new packets are received from this workstation on this port within the aging time period.
|
VQP Wrong Domain
|
Number of times the management domain in the request does not match the one for the VMPS. Any previous VLAN assignments of the port are not changed. This response means that the server and the client have not been configured with the same VQP management domain.
|
VQP Wrong Version
|
Number of times the version field in the query packet contains a value that is higher than the version supported by the VMPS. The VLAN assignment of the port is not changed. The switches send only VMPS Version 1 requests.
|
VQP Insufficient Resource
|
Number of times the VMPS is unable to answer the request because of a resource availability problem. If the retry limit has not yet been reached, the client repeats the request with the same server or with the next alternate server, depending on whether the per-server retry count has been reached.
