MSTP operation, this is the priority of the CIST. Otherwise, this is the priority
of the STP/RSTP Bridge.
Default is 32768.
Forward Delay: The delay used by STP Bridges to transit Root and Designated Ports to
Forwarding state (used in STP compatible mode). Valid values are in the
range 4 to 30 seconds.
Default is 15 seconds.
Max Age: The maximum age of the information transmitted by the Bridge, when it is
the Root Bridge. Valid values are in the range of 6 to 40 seconds, and
MaxAge must be <= (FwdDelay-1)*2.
Default is 20.
Maximum Hop Count: 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. Valid values are in the
range 6 to 40 hops.
Transmit Hold Count: 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: 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 will enter the error-disabled state, and will be
removed from the active topology.
Port Error Recovery: Controls whether a port in the error-disabled state will automatically 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 to pass before a port in the error-disabled state can be enabled.
Valid values are between 30 and 86400 seconds (24 hours).
Reset Button: Used to reset unsaved changes to original configuration.
Apply Button: Used to save the settings configured on this page.
