Step 4
bandwidth {kbps | percent value}
Example:
RP/0/RP0/CPU0:router(config-pmap-c)# bandwidth
percent 50
Enters policy map class configuration mode.
• Specifies the bandwidth allocated for a class belonging
to a policy map.
• In this example, class class1 is guaranteed 50 percent of
the interface bandwidth.
Step 5
bandwidth remaining percent value
Example:
RP/0/RP0/CPU0:router(config-pmap-c)# bandwidth
remaining percent 20
Specifies how to allocate leftover bandwidth to various
classes.
• The remaining bandwidth of 40 percent is shared by
class class1 and class2 (see Steps 8 and 9) in a 20:80
ratio: class class1 receives 20 percent of the 40 percent,
and class class2 receives 80 percent of the 40 percent.
Step 6
exit
Example:
RP/0/RP0/CPU0:router(config-pmap-c)# exit
Returns the router to policy map configuration mode.
Step 7
class class-name
Example:
RP/0/RP0/CPU0:router(config-pmap)# class class2
Specifies the name of a different class whose policy you
want to create or change.
Step 8
bandwidth {kbps | percent value}
Example:
RP/0/RP0/CPU0:router(config-pmap-c)# bandwidth
percent 10
Specifies the bandwidth allocated for a class belonging to a
policy map.
• In this example, class class2 is guaranteed 10 percent of
the interface bandwidth.
Step 9
bandwidth remaining percent value
Example:
RP/0/RP0/CPU0:router(config-pmap-c)# bandwidth
remaining percent 80
Specifies how to allocate leftover bandwidth to various
classes.
• The remaining bandwidth of 40 percent is shared by
class class1 (see Steps 4 and 5) and class2 in a 20:80
ratio: class class1 receives 20 percent of the 40 percent,
and class class2 receives 80 percent of the 40 percent.
Step 10
exit
Example:
RP/0/RP0/CPU0:router(config-pmap-c)# exit
Returns the router to policy map configuration mode.
Step 11
exit
Example:
RP/0/RP0/CPU0:router(config-pmap)# exit
Returns the router to global configuration mode.
Step 12
interface type instance
Example:
RP/0/RP1/CPU0:router(config)# interface POS
0/2/0/0
Enters interface configuration mode and configures an
interface.
