STP Configuration
The Spanning Tree Configuration/Status page contains fields for enabling STP on the switch. To display the Spanning Tree Configuration/Status page, click Switching > STP > Basic STP Configuration.
1. Use Spanning Tree Admin Mode to specify whether spanning tree operation is enabled
on the switch. Value is enabled or disabled.
2. Use Force Protocol Version to specify the Force Protocol Version parameter for the switch.
The options are IEEE 802.1d, IEEE 802.1w and IEEE 802.1s.
3. Use Configuration Name to specify an identifier used to identify the configuration currently
being used. It may be up to 32 alphanumeric characters.
4. Use Configuration Revision Level to specify an identifier used to identify the configuration
currently being used. The values allowed are between 0 and 65535. The default value is 0.
5. Use Forward BPDU while STP Disabled to specify whether spanning tree BPDUs should
be forwarded or not while spanning-tree is disabled on the switch. Value is enabled or disabled.
6. Use BPDU Guard to specify whether the BPDU guard feature is enabled. The STP BPDU
guard allows a network administrator to enforce the STP domain borders and keep the active topology consistent and predictable. The switches behind the edge ports that have STP BPDU guard enabled will not be able to influence the overall STP topology. At the reception of BPDUs, the BPDU guard operation disables the port that is configured with this option and transitions the port into disable state. This would lead to administrative disable of
7. Use BPDU Filter to specify whether the BPDU Filter feature is enabled. STP BPDU filtering
applies to all operational edge ports. Edge Port in an operational state is supposed to be connected to hosts that typically drop BPDUs. If an operational edge port receives a BPDU, it immediately loses its operational status. In that case, if BPDU filtering is enabled on this port then it drops the BPDUs received on this port.
Field Description
Configuration digest key Identifier used to identify the configuration currently being used.
MST ID Table consisting of the MST instances (including the
CST) and the corresponding VLAN IDs associated with each of them.
VID ID Table consisting of the VLAN IDs and the
corresponding FID associated with each of them.
FID ID Table consisting of the FIDs and the corresponding
