Known-<port type> Port <nn>
— A known address on port nn. The port number “nn” can be followed by
SRT
which means that the address is known as source of frames
that shall be switched using the SRT switching mode. If a BRF is
configured for SRT/SRB mode, a MAC address can be known both as
an SRT address and as an SRB address.
— <port type> can be:
TR—
The address is known at the specified Token-Ring port.
ATM

Port
—In this case “nn” will appear as <box number>/<port number>.
The address is known at a port of another switch in the stack.
If the address has occurred as a destination address in
incoming frames at other ports, it will be present in these
ports too.

— The address is a group address or a functional address and has occurred
as a destination address in incoming frames at one or more ports.
•
STP Multicast
— The group address used as a destination address in IEEE Spanning
