smart-link { vpls-notify | vll-notify } enable

Function

The smart-link { vpls-notify | vll-notify } enable command enables an interface to notify the VPLS/VLL module when the interface receives a Flush packet.

The undo smart-link { vpls-notify | vll-notify } enable command cancels the configuration.

By default, an interface does not notify the VPLS/VLL module when receiving a Flush packet.

Only the S5720-EI, S5720-HI, S5730-HI, S5731-H, S5731S-H, S5732-H, S6720-EI, S6720-HI, S6720S-EI, S6730S-H and S6730-H support this command.

Usage Guidelines

Usage Scenario

If a customer edge (CE) device is dual homed to a VPLS or VLL network through VLANIF interfaces or dot1q sub-interfaces of a provider edge (PE) device, associate Smart Link with VPLS on the corresponding physical interfaces of the PE device. If the VLANIF interfaces or dot1q sub-interfaces are bound to VSI or VLL run the smart-link flush receive and smart-link { vpls-notify | vll-notify } enable commands on the corresponding physical interfaces. Then the physical interfaces can notify the VPLS or VLL module when receiving a Flush packet. The VPLS or VLL module then deletes the MAC addresses learned from the VSI or VLL bound to the VLANIF interfaces or dot1q sub-interfaces, and sends messages to remote devices, instructing them to update MAC address entries.

Prerequisites

The VPLS or VLL configuration has been completed on the backbone network. The Smart Link configuration has been completed on the CE interfaces connected to the PE device. The VLANIF interfaces or dot1q sub-interfaces of the PE device connected to the CE device have been bound to VSI or VLL. The physical interfaces connected to the CE device have been enabled to accept Flush packets by using the smart-link flush receive command.

Precautions

You can associate Smart Link with VPLS or VLL only when a CE device is connected to the VPLS or VLL network through VLANIF interfaces or dot1q sub-interfaces of a PE device. Smart Link cannot be associated with VPLS or VLL when the CE device is connected to the VPLS or VLL network through physical interfaces.

Example

# Enable XGE0/0/1 to notify the VPLS module when the interface receives a Flush packet.
