5. Select the Admin Mode Disable or Enable radio button.
This specifies whether spanning tree operation is enabled on the switch. The default is
Enable.
6. Use Force Protocol V
ersion to specify the Force Protocol Version parameter for the
switch.
The options are IEEE 802.1d, IEEE 802.1w, IEEE 802.1s, PVST, and RPVST. The default
is IEEE 802.1w
.
7. Use Configuration Name to specify the identifier used to identify the configuration currently
being used.
It can be up to 32 alphanumeric characters.
8. Use Configuration Revision Level to specify the identifier used to identify the configuration
currently being used.
The values allowed are between 0 and 65535. The default value is 0.
9. Select the Forward BPDU while STP Disabled Disable or Enable radio button.
This specifies whether spanning tree BPDUs are forwarded while spanning-tree is
disabled on the switch.
The default is Disable.
10. Select the BPDU Guard Disable or Enable radio button.
This specifies 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 with STP BPDU guard
enabled do not 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 an administrative disable of the port.
