Syntax
broadcast-suppression pct
undo broadcast-suppression
View

Parameter
pct: Specifies the maximum wire speed ratio of the broadcast traffic allowed on the
Ethernet port. It ranges from 5 to 100 and defaults to 100. The smaller the ratio is, the
smaller the broadcast traffic is allowed.
Description
Use the broadcast-suppression command to restrict the broadcast traffic size on the
port. Once broadcast traffic exceeds the specified value, the system starts discarding
broadcast packets until the broadcast traffic decreased below the acceptable degree.
Use the undo broadcast-suppression command to restore the default (100), allowing
all broadcast traffic to pass through without broadcast suppression.
Related command: display VLAN.
Example
# Allow 20% of broadcast traffic to pass, meaning 80% of broadcast traffic is
suppressed on the port.
