Object Description
• Edge Port BPDU
Filtering
Control whether a port explicitly configured as Edge will transmit and
receive BPDUs.
• Edge Port BPDU
Guard
Control whether a port explicitly configured as Edge will disable itself
upon reception of a BPDU. The port will enter the error-disabled state,
and will be removed from the active topology.
• Port Error Recovery
Control 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).
The 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 to co-work with another STP (802.1D)’s BPDU control packet.
