(Optional) Configuring Traffic Suppression Associated with MAC Address Flapping
Context
By default, traffic suppression associated with MAC address flapping takes effect based on the type of packets (unknown unicast, multicast, and broadcast packets). The suppression threshold is a bandwidth percentage, and the percentage is 1%. That is, the percentages of unknown unicast, multicast, and broadcast packets are all 1%. You can run the storm suppression mac-address flapping command to configure the CIR for traffic suppression associated with MAC address flapping or enable the device to forcibly forward packets based on the threshold for traffic suppression associated with MAC address flapping.
The CE12800E does not support this command after having the ED-E, EG-E, and EGA-E series cards installed.
Procedure
- Run system-view
The system view is displayed.
- Run storm suppression mac-address flapping cir cir-value [ gbps | mbps | kbps ] [ force ]
The threshold for traffic suppression associated with MAC address flapping is configured.
By default, traffic suppression associated with MAC address flapping takes effect based on the type of packets (unknown unicast, multicast, and broadcast packets). The suppression threshold is a bandwidth percentage, and the percentage is 1%. That is, the percentages of unknown unicast, multicast, and broadcast packets are all 1%.
- Traffic suppression associated with MAC address flapping does not take effect on peer-link ports.
- When force is not specified in the storm suppression mac-address flapping command or this command is not configured, traffic suppression configured on interfaces takes effect in the event of MAC address flapping.
- When force is specified, traffic suppression associated with MAC address flapping takes effect even if traffic suppression is also configured on interfaces.
- When storm control is configured on interfaces, traffic suppression associated with MAC address flapping does not take effect no matter whether force is specified.
- When the multicast function is enabled, traffic suppression associated with MAC address flapping does not take effect.
- Run commit
The configuration is committed.
