Spanning Tree / Bridge Setting
This page allows you to configure STP system settings. The settings are used by all
STP Bridge instances in the Switch.
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.
