Configuring Traffic Suppression on an Interface
Context
Excess broadcast, multicast, unknown unicast or unicast packets will cause broadcast storms. You can configure traffic suppression for a specified type of packet on an interface to limit the rate of these packets.
Pre-configuration Tasks
Before configuring traffic suppression on an interface, configure link layer protocol parameters for interfaces to ensure that the link layer protocol status on the interfaces is Up.
Procedure
- Run system-view
The system view is displayed.
- Run interface interface-type interface-number
The interface view is displayed.
- Run { storm suppression broadcast | storm suppression multicast | storm suppression unknown-unicast | storm suppression unicast } { percent-value | cir cir-value [ gbps | mbps | kbps ] [ cbs cbs-value [ bytes | mbytes | kbytes ] ] }
Traffic suppression is configured.
- For incoming packets of the same type on an interface, you can only configure either traffic suppression or storm control.
On an interface, traffic suppression can be configured for either unicast traffic or unknown unicast traffic.
Traffic suppression cannot be configured on an Eth-Trunk member interface, and the percent mode of traffic suppression is not supported on an Eth-Trunk except for the CE12800E.
- Traffic suppression cannot be configured on an Eth-Trunk of the CE12800E.
- Run { storm suppression broadcast | storm suppression multicast | storm suppression unknown-unicast } block outbound
The interface is configured to block outgoing packets.
- Run commit
The configuration is committed.
