The options for displaying MAC addresses are described below.

View All MAC Addresses
This option displays both static and dynamic MAC addresses.

View All Dynamic Addresses
This option displays only dynamic MAC address. Dynamic MAC
addresses are addresses that the switch has learned by examining
the source addresses of frames received on the ports.

View All Static Addresses
This option displays only the static MAC addresses. Static MAC
addresses are addresses that you entered manually into the MAC
address table.

View by Multicast
This option displays the multicast MAC addresses.

View By Port
The pull-down menu with this option is used to display the MAC
addresses learned on a particular port.

View By VLAN ID
This option displays the MAC addresses learned by a particular
VLAN on the switch. You specify the VLAN by its VID.

4. Once you have selected one of the options, click View.

The MAC addresses are displayed in a window. The columns in the
window are defined below:

MAC
The MAC address of the node connected to the switch.

Port
The port on the switch where the MAC address was learned.

PMAP
The ports on the switch that are members of a multicast group.
This column is useful in determining which ports belong to
different multicast groups. It maps ports to multicast groups. (The
abbreviation PMAP is derived from “port mapping.”)

Each “0” is a hexadecimal value for the binary value “0000”. Each
binary “0” represents a port on the switch. A binary “0” means that
the port is not a member of a multicast group while a “1” means
that it is.

The port numbering scheme is from right to left. As an example,
assume that ports 1 through 4 on the switch were members of the
same multicast group. The PMAP column for the address would
represent this as follows: “0000000F”. Another example is
“000020F. This example would indicate that ports 1 to 4 and port
10 on the switch were members of the same multicast group.
