4.3.7 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 <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 | inter-
face <
slot/port
> | vlan <vlan_id>}]
Mode
Privileged EXEC
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
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.
Interface
The port through which this address was learned.
Interface Index
This object indicates the ifIndex 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 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 <slot/port> parameter, in addition to the MAC Address and
Status fields, the following field appears:
VLAN ID
The VLAN on which the MAC address was learned.
The following information displays if you enter the count parameter:
Dynamic Address count
Number of MAC addresses in the forwarding data-
base that were automatically learned.
