Description This command enables the context to configure ingress and egress percentage of rate parameters. This com-
mand only applies to physical ports (for example, it will not work on APS or similar logical ports). The per-
centage 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-per-
centage-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 band-
width 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 mod-
ify the current ingress active bandwidth of the port. This does not actually change the bandwidth avail-
able 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 1 — 1000
Default 100 (no change to active rate)
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 com-
mand sets rate-percentage to 100%.
egr-percentage-of-rate
Syntax egr-percentage-of-rate rate-percentage
no egr-percentage-of-rate
Context config>port>modify-buffer-allocation-rate
Description The egr-percentage-of-rate command is used to increase or decrease the active bandwidth associated with
the egress port that affects the amount of egress buffer space managed by the port. Changing a ports active
bandwidth using the egr-percentage-of-rate command is an effective means of artificially lowering the buf-
fers managed by one egress port and giving them to other egress ports on the same MDA.
