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
buffers managed by one egress port and giving them to other egress ports on the same MDA.
The egr-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 egr-percentage-of-rate command and
restores the egress 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 egress 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 egress active
bandwidth of the port. A value of 150 results in an increase of 50% (1.5 x Rate).
Values
1 to 1000
Default
100 (no change to active rate)
The no egr-percentage-of-rate command is used to remove any artificial increase or decrease of the egress
active bandwidth used for egress buffer space allocation to the port. The no egr-percentage-of-rate command
sets rate-percentage to 100%.

Description This command applies egress scheduler overrides. When a port scheduler is associated with an egress port, it
is possible to override the following parameters:
• The max-rate allowed for the scheduler.
• The maximum rate for each priority level 8 through 1.
• The CIR associated with each priority level 8 through 1.
