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 All IP Multicast Addresses
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.
View Port by MAC Address
This option is used to determine the port on the switch to which
an end node is communicating with the switch. To use this option,
enter the MAC address of the node in the field.
5. 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 Address
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. (The abbreviation PMAP is derived
from “port mapping.”)
Each “0” is a hexadecimal value, representing fours ports on the
switch. The hexadecimal value is arrived at from the binary value
“0000”, where each binary “0” represents a switch port. 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.
