Description
Edge Port BPDU
Filtering
Controls whether a port explicitly configured as Edge will transmit and
receive BPDUs.
Edge Port BPDU
Guard
Controls whether a port explicitly configured as Edge will disable itself upon
reception of a BPDU. The port enters the error-disabled state, and is
removed from the active topology.
Port Error Recovery
Controls whether a port in the error-disabled state automatically will be
enabled after a certain time. If recovery is not enabled, ports have to be
disabled and re-enabled for normal STP operation. The condition is also
cleared by a system reboot.
Port Error Recovery
Timeout
The time that has to pass before a port in the error-disabled state can be
enabled. Valid values are between
30
and
86400
seconds (24 hours).
Note:
The industrial managed switch implements the rapid spanning protocol as the
default spanning tree protocol. When selecting “Compatibles” mode, the system uses
the RSTP (802.1w) to be compatible and work with another STP (802.1D)’s BPDU
control packet.
