Viewing MAC Addresses
The MAC Address Table keeps track of the
addresses that are associated with each port. This table
allows the device to forward unicast traffic through the appropriate port. The MAC address table is
sometimes called the bridge table or the

Table 7: MAC Address Table Fields
Field
Description
VLAN ID
The VLAN with which the MAC address is associated. A MAC address can be associated
with multiple VLANs.
MAC Address
A unicast MAC address for which the switch has forwarding and/or filtering information.
The format is a six-byte MAC address, with each byte separated by colons.
Interface
The port where this address was learned. The port identified in this field is the port
through which the MAC address can be reached.
Interface Index
The Interface Index of the MIB interface table entry associated with the source port. This
value helps identify an interface when using SNMP to manage the device.
Status
Information about the entry and why it is in the table, which can be one of the following:
•
Static – The address has been manually configured and does not age out.
•
Learned – The address has been automatically learned by the device and can age out
when it is not in use. Dynamic addresses are learned by examining information in
incoming Ethernet frames.
•
Management – The burned-in MAC address of the device.
•
Self – The MAC address belongs to one of the device's physical interfaces.
•
GMRP Learned – The address was added dynamically by the
Attribute Registration Protocol)
Multicast Registration Protocol.
•
Other – The address was added dynamically through an unidentified protocol or
method.
•
Unknown – The device cannot determine the status of the entry.
