7.2.2.1 show mac-addr-table
This command displays the forwarding database entries. If the command is entered with no parameter,
the entire table is displayed. This is the same as entering the optional all parameter. Alternatively, the
administrator can enter a MAC Address to display the table entry for the requested MAC address and all
entries following the requested MAC address.
Syntax
show mac-addr-table [{<macaddr> <vlanid> |all}]
<macaddr> - enter a MAC Address to display the table entry for the requested MAC address.
<vlanid> - VLAN ID (Range: 1 – 3965)
all – this command displays the entire table.
Default Setting

Display Message
Mac Address: A unicast MAC address for which the switch has forwarding and/or filtering
information. The format is 6 or 8 two-digit hexadecimal numbers that are separated by colons, for
example 01:23:45:67:89:AB. In an IVL system the MAC address will be displayed as 8 bytes. In an
SVL system, the MAC address will be displayed as 6 bytes. Note: This software version only
supports IVL systems.
Interface: The port on which this L2 MAC address was learned.
if Index: This object indicates the if Index of the interface table entry associated with this port.
Status: The status of this entry.
The meanings of the values are:
Static: The value of the corresponding instance was added by the system or a user when a static
MAC filter was defined. It cannot be relearned.
Learned: The value of the corresponding instance was learned by observing the source MAC
addresses of incoming traffic, and is currently in use.
Management: The value of the corresponding instance (system MAC address) is also the value of
an existing instance of dot1dStaticAddress. It is identified with interface 3/1 and is currently used
when enabling VLANs for routing.
Self: The value of the corresponding instance is the address of one of the switch’s physical
interfaces (the system’s own MAC address).
GMRP Learned: The value of the corresponding instance was learned via GMRP and applies to
Multicast.
Other: The value of the corresponding instance does not fall into one of the other categories.
