Section I: Basic Operations

ADD SWITCH FDB|FILTER

Syntax

add switch fdb|filter destaddress|macaddress=

macaddress

port=

port

vlan=

name

|vid

Note

The FDB and FILTER keywords are equivalent.

Parameters

destaddress or

Specifies the static unicast or multicast address to be

macaddress

added to the switch’s MAC address table. The
parameters are equivalent. The address can be
entered in either of the following formats:

xxxxxxxxxxxx or xx:xx:xx:xx:xx:xx

port

Specifies the port(s) where the MAC address is to be
assigned. You can specify only one port when adding
a unicast address. You can specify more than one
port when adding a multicast address.

vlan

Specifies the name or VID of the VLAN where the
node designated by the MAC address is a member.

Description

This command adds static unicast and multicast MAC addresses to the
switch’s MAC address table. A MAC address added with this command is
never timed out from the MAC address table, even when the end node or,
in the case of a multicast address, the multicast application is inactive.

If you are entering a static multicast address, the address must be
assigned to the port when the multicast application is located and to the
ports where the host nodes are connected. Assigning the address to only
the port where the multicast application is located will result in the failure
of the multicast packets to be properly forwarded to the host nodes.

Examples

The following command adds the static MAC address 00:A0:D2:18:1A:11
to port 7. It assumes the port where the MAC address is to be assigned is
a member of the Default_VLAN:

add switch fdb macaddress=00A0D2181A11 port=7
vlan=default_vlan
