access-allocation-weight
Syntax access-allocation-weight buffer-allocation-weight
no access-allocation-weight
Context config>qos>named-pool-policy>q1-pools>pool>application-weights
Description The access-allocation-weight command is used to define the weight used when dividing access
associated buffer space between the named pools. When the named pool is created on an XMA or
MDA, the access associated buffer space is summed from all ports. The pool's access allocation weight
is divided by the total access allocation weights from all named pools on the XMA or MDA. The
resulting factor is multiplied by the summed port access associated buffer space to derive the amount
of access buffers applied to the pool. When the named pool is created on a port, the weight is applied
against the local ports access associated buffer space to derive the access buffers applied to the pool.
A similar process is done for with the network-allocation-weight. The total buffers applied to the pool
are the sum of the access and network buffers given to the pool.
Changing the weight does not change the total buffers allocated to the pools, just the ratio of
distribution between the pools.
A weight of '0' indicates that the pool will not receive any access associated buffers. If all pools on the
port, XMA, or MDA have a access-allocation-weight equal to 0, the access associated buffer will not
be used at that level.
Parameters buffer-allocation-weight — The buffer-allocation-weight parameter is required when executing
slope-policy
Syntax slope-policy slope-policy-name
no slope-policy
Context config>qos>named-pool-policy>q1-pools>pool
Description
The slope-policy command is used to override the default slope-policy configuration for the named
buffer pool. The specified slope-policy-name must exist as a current slope policy name. If the slope
policy does not exist, the slope-policy command will fail. If a slope policy is currently associated with
a named pool within a named pool policy, the slope policy cannot be removed from the system.
Quality of Service Guide
the access-allocation-weight command. A value of 0 to 100 is accepted. The default weight
is 50. The weight value may be changed at anytime resulting in a redistribution of access
associated buffers among the pools at the XMA, MDA, or port level.
Unit: Integer
Values
0 to 100
Default 50
The no access-allocation-weight command is used to return the pools access allocation
weight to the default value of 50.
