2service-policy
Use the service-policy interface configuration command to apply a policy map defined by the policy-map command to the input of a particular interface. Use the no form of this command to remove the policy map and interface association.
service-policy input policy-map-name
no service-policy input policy-map-name
This command is available only if your switch is running the enhanced software image (EI).
Syntax Description
Defaults
No policy maps are attached to the interface.
Command Modes
Interface configuration
Command History
Usage Guidelines
Only one policy map per ingress interface is supported.
Service policy maps cannot be defined on egress interfaces.
Note
For more information about configuring access control lists (ACLs), refer to the "Configuring Network Security with ACLs" chapter in the Catalyst 2950 Desktop Switch Software Configuration Guide for this release.
Examples
This example shows how to apply plcmap1 to an ingress interface:
Switch(config)# interface gigabitethernet0/1Switch(config-if)# service-policy input plcmap1You can verify your settings by entering the show policy-map privileged EXEC command.
Related Commands
Creates or modifies a policy map that can be attached to multiple interfaces to specify a service policy.
Displays quality of service (QoS) policy maps.
set
Use the set policy-map class configuration command to classify IP traffic by setting a Differentiated Services Code Point (DSCP) value. Use the no form of this command to remove traffic classification.
set ip dscp new-dscp
no set ip dscp new-dscp
This command is available only if your switch is running the enhanced software image (EI).
Syntax Description
new-dscp
New DSCP value assigned to the classified traffic.
The supported DSCP values are 0, 8, 10, 16, 18, 24, 26, 32, 34, 40, 46, 48, and 56.
Defaults
No traffic classification is defined.
Command Modes
Policy-map class configuration
Command History
Usage Guidelines
The set command can be used in a policy with a match command.
The set command sets the DSCP value for in-profile packets.
Note
To return to policy-map configuration mode, use the exit command. To return to privileged EXEC mode, use the end command.
Note
Examples
This example shows to assign a DSCP value of 10 to all FTP traffic without any policers:
Switch(config)# policy-map policy_ftpSwitch(config-pmap)# class ftp_classSwitch(config-pmap-c)# set ip dscp 10Switch(config-pmap)# exitYou can verify your settings by entering the show policy-map privileged EXEC command.

On a member switch, this command displays the identity of the command switch, the switch member number, and the state of its connectivity with the command switch.
On a command switch, this command displays the cluster name and the total number of members. It also shows the cluster status and time since the status changed. If redundancy is enabled, it displays the primary and secondary command-switch information.
If you enter this command on a switch that is not a cluster member, the error message Not a management cluster member appears.

show cluster candidates
Use the show cluster candidates privileged EXEC command on the command switch to display a list of candidate switches.
show cluster candidates [detail | mac-address H.H.H.] [ | {begin | exclude | include} expression]
Syntax Description
Command Modes
Privileged EXEC
Command History
Usage Guidelines
You should only enter this command on a command switch.
If the switch is not a command switch, the command displays an empty line at the prompt.
The SN in the output means switch member number. If E is 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 command switch.

show controllers ethernet-controller
Use the show controllers ethernet-controller privileged EXEC command to display the Ethernet link send and receive statistics on a Fast Ethernet or Long-Reach Ethernet (LRE) port.
show controllers ethernet-controller [interface-id] [cpe [port port-id] [ | {begin | exclude | include} expression]
Syntax Description
Command Modes
Privileged EXEC
Command History
Usage Guidelines
Using the show controllers ethernet-controller command without specifying a Fast Ethernet or LRE port displays the Ethernet link statistics of all Ethernet ports on the switch. The output shows the internal switch statistics, the statistics collected by the LRE interface on the switch, and if the CPE option is specified, the statistics collected by the LRE interface on the connected customer premises equipment (CPE) devices.
The CPE Ethernet link on a switch LRE port is the connection between the Cisco LRE CPE and the remote Ethernet device (such as a PC) connected to it. It is not the link between the switch LRE port and the LRE CPE device.

show controllers lre cpe identity
Use the show controllers lre cpe identity privileged EXEC command to display the model numbers of the Long-Reach Ethernet (LRE) customer premises equipment (CPE) devices connected to the LRE switch. This command also shows whether or not the connected CPE devices meet the minimum requirements for management by the LRE switch.
show controllers lre cpe identity [interface-id] [ | {begin | exclude | include} expression]
Syntax Description
Command Modes
Privileged EXEC
Command History
Usage Guidelines
This command shows the type of CPE device attached to each LRE interface. For all Cisco supported CPE devices, the status can be certified, non-certified, or NA:
A certified status means that the CPE device meets the minimum requirements (such as having a certain CPE device patch version) for management by the LRE switch.
A non-certified status means that the CPE device did not meet the minimum requirements. If a CPE device shows a status of non-certified, or if the family is not a Cisco 585 LRE CPE, Cisco 576 LRE 997 CPE, or a Cisco 575 LRE CPE, use the show controllers lre cpe mfg command to verify the validity of the CPE manufacturing fields.
A NA status means that there is not a link or there is not any information about that port.
Using the show controllers lre cpe identity command without specifying a switch LRE port displays the model numbers and status of all connected CPE devices.
Examples
This is an example of output from the show controllers lre cpe identity command for the Cisco 575 LRE and Cisco 585 LRE CPE devices:
