Once a stable network topology has been established, all bridges listen for Hello BPDUs (Bridge Protocol Data Units)
transmitted from the Root Bridge. If a bridge does not get a Hello BPDU after a predefined interval (Maximum Age), the
bridge assumes that the link to the Root Bridge is down. This bridge will then initiate negotiations with other bridges
to reconfigure the network to reestablish a valid network topology.
3.4.1 Bridge Settings
The section describes how to configure the Spanning Tree Bridge and STP System settings. It allows you to configure
STP System settings which are used by all STP Bridge instances in the Switch.
Web Interface
To configure the Spanning Tree Bridge Settings parameters in the web interface:
1. Click Configuration, Spanning Tree, Bridge Settings
2. Select the parameters and enter available values of parameters in the blank field in Basic Settings
3. Activate to enable or disable the parameters and enter available value of parameters in the blank field in Advanced
settings
4. Click Apply to save the setting
5. If you want to cancel the setting then you need to click the Reset button. It will revert to previously saved values

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.
