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.

-Default:

-Minimum:
The higher of 4 or [(Max. Message Age / 2) + 1]
-Maximum:
30
The maximum age of the information transmitted by the Bridge when it is the
Root Bridge. Valid values are in the range 6 to 40 seconds.
-Default:
20
-Minimum:
The higher of 6 or [2 x (Hello Time + 1)].
-Maximum:
The lower of 40 or [2 x (Forward Delay -1)]
This defines the initial value of remaining Hops for MSTI information generated at
the boundary of an MSTI region. It defines how many bridges a root bridge can
distribute its BPDU information. Valid values are in the range 6 to 40 hops.
The number of BPDU's a bridge port can send per second. When exceeded,
transmission of the next BPDU will be delayed. Valid values are in the range 1 to
10 BPDU's per second.
Description
Control whether a port explicitly configured as Edge will transmit and receive
BPDUs.
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.
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.
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).
