config>vsm>ccag ccag-id>path {a | b}>net-sap>egress>pool
Description
This command defines the percentage of the buffer pool that is considered reserved for the CBS
buffer allocation for queues created in the path's pool context.
The no form of the command returns the reserved portion of the buffer pool to the default percentage.
Parameters percentage-of-pool — The percentage-of-pool parameter defines the percentage of the buffer pool
slope-policy
Syntax slope-policy slope-policy-name

Context config>vsm>ccag ccag-id>path {a | b}>sap-sap>egress>pool
config>vsm>ccag ccag-id>path {a | b}>sap-sap>ingress>pool
config>vsm>ccag ccag-id>path {a | b}>sap-net>egress>pool

config>vsm>ccag ccag-id>path {a | b}>net-sap>egress>pool
Description
This command defines the slope policy used to mange the shared portion of the buffer pools WRED
slopes. The commands in the policy control the administrative state of the slopes, the start and knee
points of each slope and the time-average-factor for the weighted average buffer utilization
calculation.
The no form of the command configures the default slope policy as the managing policy for the
buffer pool.
Parameters
slope-policy-name — Defines the name of the WRED slope policy used to manage the WRED slopes

that is not considered shared. The shared portion of the pool is used by queues that have crossed
their CBS buffer threshold and is subject to the WRED slope functions. The reserved portion of
the pool is used by queues that have not crossed their CBS threshold. The aggregate CBS on the
queues associated with the pool may oversubscribe the resv-cbs percentage. If the reserved
portion is oversubscribed and the in-use reserved buffers exceed the defined percentage, buffers
are removed from the shared portion of the pool.
Values
1 to 100 (percent)
Default
30
in the shared portion of the buffer pool.
Values
Any existing slope policy name.
