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.
