Parameter
: Specifies the bandwidth ratio of broadcast traffic allowed on an Ethernet
ratio
port. The ratio value ranges from 1 to 100. The incremental step is 1. By default,
the ratio is 100 meaning all broadcast traffic is accepted. The smaller the ratio is,
the less bandwidth is allocated to broadcast traffic and therefore less broadcast
traffic is accepted on the Ethernet port.
: Specifies the maximum number of broadcast packets per second
pps
pps
accepted on an Ethernet port. Ranges from 1 to 148810 pps.
Description
Use
broadcast-suppression
will be accepted on a port. Once the broadcast traffic exceeds the value set by the
user, the excess broadcast traffic will be discarded. This feature can be used to
ensure network service and prevent broadcast storms.
Example
Enable a limit of 20% of the available bandwidth on a port to be allocated to
broadcast traffic. Broadcast traffic exceeding 20% of the ports bandwidth will be
discarded.
