Named Pools QoS Policy Command Reference
application-weights
Syntax application-weights
Context config>qos>named-pool-policy>q1-pools>pool
Description The application-weights CLI node context contains the network and access allocation weights. The
network and access application weights are used to divide the network and access buffer space
available to the pools between each named pool. When the policy is applied at the XMA or MDA level,
the network and access application weights are applied to the network and access buffer space given
to the XMA or MDA named pools by the ingress or egress ports. When the policy is applied at the port
level, the network and access application weights are applied to the local port network and access
buffer space.
network-allocation-weight
Syntax network-allocation-weight buffer-allocation-weight
no network-allocation-weight
Context config>qos>named-pool-policy>q1-pools>pool>application-weights
Description
The network-allocation-weight command is used to define the weight used when dividing network
associated buffer space between the named pools. When the named pool is created on an XMA or
MDA, the network associated buffer space is summed from all ports. The pool's network allocation
weight is divided by the total network allocation weights from all named pools on the XMA or MDA.
The resulting factor is multiplied by the summed port network associated buffer space to derive the
amount of network buffers applied to the pool. When the named pool is created on a port, the weight
is applied against the local ports network associated buffer space to derive the network buffers applied
to the pool. A similar process is done for with the access-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 network associated buffers. If all pools on
the port, XMA, or MDA have a network-allocation-weight equal to 0, the network associated buffer
will not be used at that level.
The no form of the command returns the pools network allocation weight to the default value of 50.
Parameters buffer-allocation-weight — The buffer-allocation-weight parameter is required when executing
734
the network-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 network
associated buffers among the pools at the XMA, MDA, or port level.
