Named Pools
Quality of Service Guide 731
q1-pools
Syntax q1-pools
Context config>qos>named-pool-policy
Description The q1-pools command is used to enter the configuration node for Q1 oriented named buffer pools.
The named pool policy will support contexts for configuring pools of other types when other pool types
exist.
port-allocation-weights
Syntax port-allocation-weights default weight mda weight port weight
no port-allocation-weights
Context config>qos>named-pool-policy
Description The port-allocation-weights command is used to define the weights used to divide the buffers managed
by a port into three categories: default, XMA, MDA and port. The default category is given to the
default pools, the XMA or MDA category is given to the XMA or MDA named pools and the port
category is used by the local port named pools. When the IOM is placed in named-pool-mode, each
port has an inherent set of weights that places all port managed buffers into the default category
(default = 100, XMA or MDA = 0, port = 0). The policy port-allocation-weights command is used to
override this port inherent behavior. When the policy is applied to the XMA or MDA, the defined port-
allocation-weights parameter values override the inherent values for all ports on the XMA or MDA.
When the policy is applied to the port level, the defined port-allocation-weights override both the local
ports inherent weights and the XMA or MDA level named pool policy weights (if existing).
The no form of the command resets all values to the default value.
Parameters default weight — The default keyword is used to identify the weight value for the port where the
policy is applied used in the calculation of the amount of buffer space given to the default
pools by the port. The following weight parameter is required and must be specified as an
integer between 0 and 100. The specified weight only has meaning when compared to the mda
and port weights. The sum of all three weights is divided into each weight to determine the
amount of buffering given to the pools of each type.
Values Integers 0 to 100
Default 50
mda weight — The mda keyword is used to identify the weight value for the port where the policy
is applied used in the calculation of the amount of buffer space given to the XMA or MDA
level named pools by the port. The following weight parameter is required and must be
specified as an integer between 0 and 100. The specified weight only has meaning when
compared to the default and port weights. The sum of all three weights is divided into each
weight to determine the amount of buffering given to the pools of each type.
Values Integers 0 to 100
Default 50
