Policy-Map Commands
XSR CLI Reference Guide 12-91
Mode
Policy‐Map Class configuration: XSR(config-pmap-c-<xx>)#
Example
The following example configures two PQs for the policy map policy57, with a high priority level,
guaranteed bandwidth of 300 kbps and a one‐time allowable burst size of 500 kbps for the map‐
class voice; and a low priority bandwidth, 80 bytes of guaranteed bandwidth, and a burst size 2000
bytes for map‐class beta.
XSR(config)#policy-map policy57
XSR(config-pmap)#class voice
XSR(config-pmap-c)#priority high 300 500
XSR(config-pmap)#class beta
XSR(config-pmap-c)#priority low 80 2000
queue-limit
This command specifies or modifies the maximum number of packets the queue can hold for a
class policy configured in a policy map.
Class‐Based Weighted Fair Queueing (CBWFQ) creates a queue for every class for which a class
map is defined. Packets satisfying the match criteria for a class accumulate in the queue reserved
for the class until they are sent, which occurs when the queue is serviced by the Fair Queueing
process. When the peak packet threshold you set for the class is reached, any further packet
enqueueing to the class queue causes tail drop.
Syntax
queue-limit number-of-packets
Syntax of the “no” Form
The no form of the command removes the queue packet limit from a class. If RED is not
configured, the queue limit is restored to the default value.
no queue-limit
Mode
Policy‐Map Class configuration: XSR(config-pmap-c-<xx>)#
Default
64
Example
The following example configures policy map policy75 to contain policy for class acl203. Policy for
this class is set so that the queue reserved for it has a maximum packet limit of 50.
number-of-
packets A number ranging from 1 to 64 specifying the peak number of packets
that the queue can accomodate for this class.
