Command or Action
Step 2
policy-map policy-name
Example:
RP/0/RSP0/CPU0:router(config)# policy-map
bottom-child
Step 3
class class-name
Example:
RP/0/RSP0/CPU0:router(config-pmap)# class

Step 4 bandwidth {rate [units] | percent percentage-value}
or bandwidth remaining [percent percentage-value
| ratio ratio-value] or shape average {percent
percentage | rate [units]}
Example:
RP/0/RSP0/CPU0:router(config-pmap-c)#
bandwidth percent 30
or
RP/0/RSP0/CPU0:router(config-pmap-c)#
bandwidth remaining percent 80
or
RP/0/RSP0/CPU0:router(config-pmap-c)# shape
average percent 50
Step 5 exit
Example:
RP/0/RSP0/CPU0:router(config-pmap-c)# exit
Step 6 policy-map policy-name
Example:
RP/0/RSP0/CPU0:router(config-pmap)#
policy-map Top-Parent
Step 7
