Usage Guidelines
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 EXOS. These entries can only be created when the virtual-network is in explicit-remote flooding mode.
Example
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
