MAC Address
. The MAC address for which virtual interface and VLAN membership information
will be displayed.
Slot/Intf/Service/Instance. Specifies the virtual port for which AutoTracker VLAN information will
be displayed. The Slot is the physical slot location to which the MAC address maps. The Intf is
the physical port to which the
MAC address maps. The Service is the service type for this MAC
address. The service type may be a Router (
Rtr), Bridge (Brg), Classical IP (CIP), FDDI Trunk
(Trk), or an 802.10 Trunk (T10). Instance is the specific instance of this service type. These
different instances are identified numerically. The first instance of a service type belonging to
a physical port is identified as 1, the second instance is identified as 2, etc.
AT VLAN Membership. The AutoTracker VLANs to which this MAC Address belongs. An MAC
address may belong to more than one
VLAN. For example, let’s say a MAC device runs on an
IPX network. It could be included in a MAC Address policy for one AutoTracker VLAN and the
IPX Protocol Policy of another VLAN.
