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%.
egress-scheduler-override
Syntax [ no ] egress-scheduler-override
Context config>port>sonet-sdh>path
config>port>ethernet
config>port>tdm>ds3
config>port>tdm>ds1>channel-group
config>port>tdm>e1>channel-group
config>port>tdm>e3
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.
