In ExtremeXOS 21.1, this command was extended to delete a remote VTEP as a destination to a MAC address. Three new tokens “broadcast”, “unknown-multicast” and “unknown-unicast” have been added to this command. When you want to specify a destination to forward all broadcast or unknown unicast traffic on that VLAN, these token are used. For “broadcast”, “unknown-multicast” and “unknown-unicast” only remote VTEPs (and not port_list or blackhole) can be specified in this release of ExtremeXOS. These entries can only be created when the virtual-network is in explicit-remote flooding mode.
The following example deletes a permanent entry from the FDB:
delete fdb 00:E0:2B:12:34:56 vlan marketing
The following example deletes all permanent entries from the FDB:
delete fdb all
This command was first available in ExtremeXOS 11.0.
In ExtremeXOS 12.3, the fdb keyword was introduced as an alias to the fdbentry keyword to avoid interference with the syntax of the MAC-Tracking feature commands. Both keywords execute; however, the syntax helper (tab completion) does not recognize the fdbentry keyword.
Three new tokens “broadcast”, “unknown-multicast” and “unknown-unicast” were added to this command in ExtremeXOS 21.1.
This command is available on ExtremeSwitching X435, X440-G2, X450-G2, X460-G2, X465, X590, X620, and X695 series switches.
