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.
