Port
The port on the switch where the unicast MAC address was learned or
assigned. This column is empty for a multicast address.
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 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. This would be represented in the column 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.
This column is empty for unicast addresses.
CPU
This feature is not supported.
MIR
Indicates whether the traffic on the port is being mirrored. Yes means
the traffic is being mirrored while No indicates that it is not.
EMP
Indicates whether multicast packets are being forwarded by ports in the
blocking state. This feature is not supported at this time. This column will
indicate “No” for all multicast addresses, except for the switch’s MAC
address. Multicast packets are forwarded only by ports in the forwarding
state.
VLANID
The VID of the VLAN to which the port is an untagged member.
Type
The MAC address type. The type can be either static or dynamic.
Examples
The following command displays all MAC addresses in the switch’s MAC
address table:
show switch fdb
