Configuring Traffic Suppression on a Specified Interface in a VLAN

This section describes how to configure traffic suppression on a specified interface in a VLAN to reduce the load that a large volume of traffic poses on the network.

Context

Traffic suppression can be configured only on interfaces that work in Layer 2 mode.

If you configure traffic suppression on an interface for several times, the last configuration overrides the previous ones. Before you reconfigure traffic suppression on an interface that is added to a VLAN, delete the first configuration.

Procedure

Run system-view
The system view is displayed.
Run interface interface-type interface-number
The interface view is displayed.
Run portswitch
The working mode of the interface is switched to Layer 2.
Run vlan batch { vlan-id1 [ to vlan-id2 ] } &<1-10>
A VLAN is configured.
Run port interface-type { interface-number1 [ to interface-number2 ] } &<1-10>
The interface is added to the VLAN.
Run suppression { inbound | outbound } enable
Traffic suppression is enabled in the VLAN.
Run unknown-multicast discard
Interfaces in the VLAN are disabled from forwarding unknown multicast packets.
Run unknown-unicast discard
Interfaces in the VLAN are disabled from forwarding unknown unicast packets.
Run quit
Return to the system view.
Run interface interface-type interface-number
The interface view is displayed.
Run broadcast-suppression cir cir-value [ cbs cbs-value ] { inbound | outbound } {vlan { vlan-id1 [ to vlan-id2 ] } &<1-10> }
Broadcast traffic suppression is configured on the interface in a VLAN.
Run multicast-suppression cir cir-value [ cbs cbs-value ] { inbound | outbound } {vlan { vlan-id1 [ to vlan-id2 ] } &<1-10> }
Multicast traffic suppression is configured on the interface in a VLAN.
Run unknown-unicast-suppression cir cir-value [ cbs cbs-value ] { inbound | outbound } {vlan { vlan-id1 [ to vlan-id2 ] } &<1-10> }
Unknown unicast traffic suppression is configured on the interface in a VLAN.
Run commit
The configuration is committed.
