There have been two commands available to configure a static fdb entry in EXOS, "create fdbentry" and "create fdb".
In 16.1 and onwards including 21.x and 22.x, "create fdbentry" command has been deprecated, and only the "create fdb" command is supported for static fdb entry.
For backward compatibility, the "create fdbentry" command can be manually entered without help of syntax helper and auto-completion in CLI.
In this case, the "create fdbentry" command is automatically converted to "create fdb" command in the configuration.
|BD8800.2 # create fdbentry 00:00:00:00:00:01 "v100" ports 1:1|
BD8800.3 # show conf fdb
# Module fdb configuration.
create fdb 00:00:00:00:00:01 vlan "v100" port 1:1
