Descriptions

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 is displayed as 8 bytes.

Interface—The Unit/Slot/Port at which this address was learned.

If Index—This object indicates the IfIndex of the interface table entry associated with this port.

In the S2410, If Index values are:

Status—The status of this entry. The meanings of the values are:

macaddr

(OPTIONAL) Enter a 6 byte Mac address.

all (OPTIONAL) Enter all to get results for all interfaces.

interface unit/slot/port

(OPTIONAL) To show MAC addresses on a particular interface, enter

the keyword

interface followed by the interface unit, slot, and port.

This can be a physical or logical interface.

vlan VLAN_ID

Note: IVL (Independent VLAN Learning) allows unicast address-to-port mappings to

be created based on a MAC address in conjunction with a VLAN ID. In an IVL system,

the MAC address is displayed as 8 bytes.

Note: The “3/1” in the Interface column references the Ethernet Management port.

See Figure 13 and Figure 15.
