Software Configuration of ATM ISE Line Cards for Cisco 12000 Series Routers How to Configure Layer 3 Terminated VCs on the 4-Port ATM ISE Line Card Examples Following are examples of configuring the IP DSCP value and the ATM CLP bit: • Configuring the IP DSCP Value, page 26 • Configuring the ATM CLP Bit on a Per-Queue Basis with Per-VC MDRR, page 26 • Configuring the ATM CLP Bit on Class-Default Queue with Per-VC MDRR, page 26 • Configuring the ATM CLP Bit by Traffic Policing, page 27 Configuring the IP DSCP Value This example marks packets of class1 by setting the IP differentiated services code point (DSCP): Router(config)# policy-map QOS-SET Router(config-pmap)# class class1 Router(config-pmap-c)# set ip dscp 63 Router(config-pmap-c)# class class2 Router(config-pmap-c)# bandwidth percent 30 Router(config-pmap-c)# exit Router(config-pmap)# In the above example, class1 is configured with a nonqueueing feature. Traffic that is matched to class1 is considered to belong to this class for purposes of the nonqueueing feature, but for purposes of queueing, the packet will go into the default queue. After the policy map has been created, configure it on the VC using the service-policy command. Configuring the ATM CLP Bit on a Per-Queue Basis with Per-VC MDRR This example configures the CLP bit setting on a per-queue basis. Precedence 0 and 1 go to the queue of class prec01 with CLP bit off; precedence 2 goes to the queue of class prec2 with the CLP on; precedence 3, 4, and 5 go to the queue of class prec345 with the CLP on; all other traffic goes to the queue of class-default with the CLP bit off. Router(config)# class-map match-any prec01 Router(config-cmap)# match ip prec 0 1 Router(config)# class-map match-any prec2 Router(config-cmap)# match ip prec 2 Router(config)# class-map match-any prec345 Router(config-cmap)# match ip prec 3 4 5 Router(config)# policy-map SET_ATM_CLP Router(config-pmap)# class prec01 Router(config-pmap-c)# bandwidth percent 10 Router(config-pmap-c)# class prec2 Router(config-pmap-c)# bandwidth percent 10 Router(config-pmap-c)# set atm-clp Router(config-pmap-c)# class prec345 Router(config-pmap-c)# bandwidth percent 10 Router(config-pmap-c)# set atm-clp Router(config-pmap-c)# exit After the policy map has been created, configure it on the VC using the service-policy command. Configuring the ATM CLP Bit on Class-Default Queue with Per-VC MDRR This example configures the CLP bit setting on part of the traffic of the class-default queue. Precedence 0, 1 go to the queue of class prec01 with the CLP bit off; precedence 3, 4, and 5 go to the queue of class class-default with the CLP on; all other traffic goes to the queue of class-default with the CLP bit off.
