Bridge Settings
This page allows you to configure RSTP system settings. The settings are used by all RSTP Bridge
instances in the Switch Stack.
Label
Description
Protocol Version The STP protocol version setting. Valid values are STP, RSTP and MSTP.
Forward Delay
The delay used by STP Bridges to transition 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. Valid values are in the range 4 to 30 seconds, and MaxAge must
be <= (FwdDelay-1)*2.
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.
