Figure 3-4.1: The STP Bridge Configuration
Parameter description:
Basic Settings
Protocol Version :

The STP protocol version setting. Valid values are STP, RSTP and MSTP.
Bridge Priority :

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. For MSTP operation, this is
the priority of the CIST. Otherwise, this is the priority of the STP/RSTP bridge.
Forward Delay :

The delay used by STP Bridges to transit Root and Designated Ports to
Forwarding (used in STP compatible mode). Valid values are in the range 4 to
30 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 6 to 40 seconds, and MaxAge must
be <= (FwdDelay-1)*2.
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.
Advanced Settings
Edge Port BPDU Filtering :

Control whether a port explicitly configured as Edge will transmit and receive
