clear fdb vpls {vpls_name {peer_ip_address}}


Clears the FDB information learned for VPLS.

Syntax Description

vpls_name Clears all FDB entries for the specified VPLS and its associated This command is available on the ExtremeSwitching X440-G2, X450-G2, X460-G2, X465, X590, X620, X670-G2, X690, X695, X870, 5320, 5420, 5520 series switches..
peer_ip_address Clears all FDB entries for the pseudowire (PW) associated with the specified VPLS and LDP peer.



Usage Guidelines

If the command is used without keywords, every FDB entry learned from any PW is cleared. Using the keywords vpls_name clears every FDB entry, (both PW and front panel Ethernet port for the service VLAN) associated with the specified VPLS and the associated VLAN. If the specified VPLS is not bound to a VLAN, the following error message appears:

Error: vpls VPLS_NAME not bound to a vlan

Using the keywords vpls_name and peer_ip_address clears all FDB entries from the PW associated with the specified VPLS and LDP peer.

Once the information is cleared from the FDB, any packet destined to a MAC address that has been flushed from the hardware is flooded until the MAC address has been re-learned.


This example clears the FDB information for VPLS 1:

clear fdb vpls vpls1
