Redundancy
Parameters Meaning
Auto Edge Port The device only considers the Auto
Edge Port setting when the Admin
Edge Port parameter is deactivated.
If Auto Edge Port is active, after a
link is set up the device sets the port
to the forwarding status after
1.5 ∙ Hello Time (in the default
setting 3 s).
If Auto Edge Port is deactivated, the
device waits for the Max Age
instead (in the default setting 20 s).
This setting applies to all MSTIs.
Oper Edge Port The device sets the "Oper Edge
Port" condition to true if it has not
received any STP-BPDUs, i.e. a
terminal device is connected. It sets
the condition to false if it has
received STP-BPDUs, i.e. a bridge
is connected.
This condition applies to all MSTIs.
Oper The device sets the "Oper point-to-
PointToPoint point" condition to true if this port
has a full duplex condition to an STP
device. Otherwise it sets the
condition to false (e.g. if a hub is
connected).
The point-to-point connection
makes a direct connection between
2 RSTP devices. The direct,
decentralized communication
between the two bridges results in a
short reconfiguration time.
This condition applies to all MSTIs.

For designated ports, the device displays the information for the STP-
BPDU last received by the port. This helps with the diagnosis of possible
STP problems in the network.
