OBJECT
link - Bridge port.
fdb - Forwarding Database entry.
mdb - Multicast group database entry.
vlan - VLAN filter list.
COMMAND
Specifies the action to perform on the object. The set of
possible actions depends on the object type. As a rule, it is
possible to add, delete and show (or list ) objects, but some
objects do not allow all of these operations or have some
additional commands. The help command is available for all
objects. It prints out a list of available commands and argument
syntax conventions.
If no command is given, some default command is assumed. Usually
it is list or, if the objects of this class cannot be listed,
help.
