Protocol Version
STP/RSTP
Spanning tree protocol version
RSTP
Bridge Priority
0/4096/…../61440
Controls the bridge priority. Lower numeric values have
better priority. The bridge priority plus the MSTI instance
number, concatenated with the 6-byte MAC address of the
switch forms a Bridge Identifier.
32768
Forward Delay
4-30 second
The delay used by STP Bridges to transit Root and Desig-
nated Ports to Forwarding (used in STP compatible mode).
Valid values are in the range 4 to 30 seconds.
15
Max Age
6-40second
And <=
(Forward Delay-1) X 2
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, and Max Age must be
20
Maximum Hop
Count
6-40
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 to.
20
Transmit Hold
Count
1-10
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.

Edge Port BPDU
Filtering
Select/not select
Control whether a port explicitly configured as Edge will
transmit and receive BPDUs.
not select
Edge Port BPDU
Guard
Select/not select
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.
not select
Port Error
Recovery
Select/not select
Control whether a port in the error-disabled state auto-
matically 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.
not select
Port Error Re-
covery Timeout
30-86400 second
The time to pass before a port in the error-disabled state
can be enabled. Valid values are between 30 and 86400
seconds (24 hours).
