set port broadcast
To set broadcast, multicast, or unicast suppression for one or more ports, use the set port broadcast
command. The threshold limits the backplane traffic received from the module.
set port broadcast mod/port threshold% [violation {drop-packets | errdisable}]
[multicast {enable | disable}] [unicast {enable | disable}]
Syntax Description
Defaults The default is 100% (no broadcast limit).
The default action is drop-packets if a broadcast violation occurs.
Command Types Switch command.
Command Modes Privileged.
Usage Guidelines This command is not supported by the NAM.
You can enter the threshold value in two ways:
•A decimal number followed by a percent sign (for example 0.33%)
•A whole number followed by a percent sign (for example 33%)
The percent sign (%) is required when entering th e thre sho ld value.
