Port Role –

•
Disabled –

Root –
The port with the lowest cost that links the switch to the root bridge device.
•
Non-Designated –
(STP only) Port is blocking and not listening.
•
Alternate –
(RSTP) Port links between bridges but is not the designated port, so it is not used unless
the designated port loses connection.
•
Designated –
Port is designated as the elected link between bridges in the spanning tree.
•
Port State –
Displays what state the port is currently in. Options:
•
Disabled –
Port is not in use.
•
Blocking –
Port is not forwarding frames or reading MAC addresses because it would cause a loop,
but is listening for BPDUs. This state is reached once a different port is designated.
•
Listening –
A designated or root port moves into this state if it stops blocking due to a change in
the spanning tree. BPDUs are received from the connected segment and analyzed to determine the
ideal topology. No other frames are forwarded while a port is in this state.
•
Learning –
Once the listening process is complete, the port begins updated the MAC address table
and gets ready to start forwarding frames as normal.
•
Forwarding –
The port is an active link in the spanning tree forwarding frames as normal.
•
Migration Start –
(RSTP Mode only) Click the box and click Apply to force the port to use the newest
configuration.
