Command History
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 gigabitethernet0/1Switch(config-if)# rmon collection stats 2 owner rootYou 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.
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
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, butis currently disabled. Access to the boot loader promptthrough the password-recovery mechanism is disallowed atthis point. However, if you agree to let the system bereset back to the default system configuration, accessto 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.

service-policy (interface configuration)
Use the service-policy interface configuration command to apply a policy map defined by the policy-map command to the incoming or outgoing traffic of a physical port. Use the no form of this command to remove the policy map and port association.
service-policy {input | output} policy-map-name
no service-policy {input | output} policy-map-name
Syntax Description
input
Apply the policy map to the input of a physical port.
output
Apply the policy map to the output of a physical port.
policy-map-name
The specified policy map to be applied.
Note
Defaults
No policy maps are attached to the port.
Command Modes
Interface configuration
Command History
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 gigabitethernet0/1Switch(config-if)# service-policy output plcmap1This example shows how to remove plcmap2 from the port:
Switch(config)# interface gigabitethernet0/2Switch(config-if)# no service-policy output plcmap2You can verify your settings by entering the show running-config privileged EXEC command.

service-policy (policy-map class configuration)
Use the service-policy policy-map class configuration command to configure a quality of service (Q0S) service policy for anoutput policy map. Use the no form of this command to disable a service policy as a QoS policy within a policy map.
service-policy policy-map-name
no service-policy policy-map-name
Syntax Description
policy-map-name
Name of the service policy map (created by using the policy-map global configuration command) to be used in a QoS hierarchical service policy.
Defaults
No service policies are defined.
Command Modes
Policy-map class configuration
Command History
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-parentSwitch(config-pmap)# class class-defaultSwitch(config-pmap-c)# shape average 90000000Switch(config-pmap-c)# service-policy out-policySwitch(config-pmap-c)# exitSwitch(config-pmap)# exitYou can verify your settings by entering the show policy-map privileged EXEC command.

12.2(25)EX
This command was introduced.
12-2(25)SEG
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_ftpSwitch(config-pmap)# class ftp_classSwitch(config-pmap-c)# set cos 3Switch(config-pmap-c)# exitThis example shows how to assign a DSCP to CoS table map to a class:

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 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.

12.2(25)EX
This command was introduced.
12.2(25)SEG
Support was added to configure traffic shaping in the class-default of an output policy map.
Usage Guidelines
You use the shape average policy-map class command to control output traffic. Shaping is not supported in input policy maps.
Traffic shaping limits the rate of transmission of data. 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.

Note
Command Modes
User EXEC
Command History
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.
