show mac-addr-table
This command displays the forwarding database entries. These entries are used by the
transparent bridging function to determine how to forward a received frame.
Enter all or no parameter to display the entire table. Enter a MAC Address and VLAN ID to
display the table entry for the requested MAC address on the specified VLAN. Enter the
count parameter to view summary information about the forwarding database table. Use the
interface <unit/slot/port> parameter to view MAC addresses on a specific
interface. Use the vlan <vlan_id> parameter to display information about MAC addresses
on a specified VLAN.
Format show mac-addr-table [{<macaddr> <vlan_id> | all | count | interface
<unit/slot/port> | vlan <vlan_id>}]
Mode
The following information displays if you do not enter a parameter, the keyword all, or the
MAC address and VLAN ID. If you enter vlan <vlan_id>, only the Mac Address, Interface,
and Status fields appear.
Mac Address
Interface
Interface Index
Status
• 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
0/1. 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 was learned via GMRP and applies
to Multicast.
• Other—The value of the corresponding instance does not fall into one of the other
categories.
If you enter the interface <unit/slot/port> parameter, in addition to the MAC
Address and Status fields, the following field appears:
VLAN ID
Privileged EXEC
Term Definition
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.
The port through which this address was learned.
This object indicates the ifIndex of the interface table entry associated with this port.
The status of this entry. The meanings of the values are:
Term Definition
The VLAN on which the MAC address was learned.
