3.1.8.1. Spanning Tree - Bridge Settings
This page allows you to configure STP system settings. The settings are used by all STP
Bridge instances in the Switch Stack.
Basic Settings
Protocol Version
The MSTP / RSTP / 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.
