Forward delay
The forward delay value indicates how long the switches are to wait in order for the port state
in STP mode to change from “Discarding” to “Listening” and from “Listening” to “Learning”
(2 x forward delay).

Oper edge port
All ports that do not receive any (R)STP BPDUs (e.g., termination device ports) become
edge ports, i.e., ports that go to the “Forwarding” state immediately after restart. All ports
that do not receive any (R)STP BPDUs (e.g., termination device ports) become edge ports,
i.e., ports that go to the “Forwarding” state immediately after restart.
Protocol
Indicates the redundancy protocol used.
(R)STP state
Indicates the current (R)STP state of the relevant port.
Possible states:
–
“Forwarding”
The port is integrated in the active topology and forwards data.
– “Discarding”
The port does not take part in data transmission.
– “Learning”
The port does not take part in data transmission of the active topology, however, MAC
addresses are learned.
– Blocking/Discarding
The port has a link, but has been set to the “Discarding” state by RSTP.
The “Max Age of STP”, “Hello Time”, and “Forward Delay” parameters are optimized by
default upon delivery. They should not be modified.
