General Port Commands
modify-buffer-allocation-rate
Syntax
modify-buffer-allocation-rate
Context
config>port
Description
This command enables the context to configure ingress and egress percentage of rate parameters. This
command only applies to physical ports (for example, it will not work on APS or similar logical ports). The
percentage of rate commands are used to define a percentage value that affects the amount of buffers used by
ingress and egress port managed buffer space. Enter the modify-buffer-allocation-rate context when editing
the port's percentage of rate commands.
ing-percentage-of-rate
Syntax
ing-percentage-of-rate rate-percentage
no ing-percentage-of-rate
Context
config>port>modify-buffer-allocation-rate
Description
This command increases or decreases the active bandwidth associated with the ingress port that affects the
amount of ingress buffer space managed by the port. Changing a port's active bandwidth using the ing-
percentage-of-rate command is an effective means of artificially lowering the buffers managed by one
ingress port and giving them to other ingress ports on the same MDA.
The ing-percentage-of-rate command accepts a percentage value that increases or decreases the active
bandwidth based on the defined percentage. A value of 50% causes the active bandwidth to be reduced by
50%. A value of 150% causes the active bandwidth to be increased by 50%. Values from 1 to 1000 percent
are supported.
A value of 100 (the default value) is equivalent to executing the no ing-percentage-of-rate command and
restores the ingress active rate to the normal value.
Parameters
rate-percentage — The rate-percentage parameter is required and defines the percentage value used to
modify the current ingress active bandwidth of the port. This does not actually change the bandwidth
available on the port in any way. The defined rate-percentage is multiplied by the ingress active
bandwidth of the port. A value of 150 results in an increase of 50% (1.5 x Rate).
Values
Default
The no ing-percentage-of-rate command is used to remove any artificial increase or decrease of the ingress
active bandwidth used for ingress buffer space allocation to the port. The no ing-percentage-of-rate
command sets rate-percentage to 100%.
