Configuration Commands
Description This command configures the sharing of the egress buffers allocated to a hybrid port among the
access and network contexts. By default, it is split equally between network and access.
The no form of this command restores the default values for the egress access and network weights.
Parameters
access-weight — Specifies the access weight as an integer.
network-weight — Specifies the network weight as an integer.
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
