Description
This command enables Digital Diagnostic Monitoring (DDM) events for the port.
The no form of the command disables DDM events.
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 1 to 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 command sets rate-percentage to 100%.
