1. Use Spanning Tree Admin Mode to specify whether spanning tree operation is enabled
on the switch. Value is enabled or disabled. The default is Enable.
2. Use Force Protocol V
ersion to specify the Force Protocol Version parameter for the
switch. The options are IEEE 802.1d, IEEE 802.1w, and IEEE 802.1s. The default is IEEE
802.1w.
3. Use Configuration Name to specify the identifier used to identify the configuration currently
being used. It may be up to 32 alphanumeric characters.
4. 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.
5. Use Forward BPDU while STP Disabled to specify whether spanning tree BPDUs should
be forwarded while spanning-tree is disabled on the switch. V
alue is enabled or disabled.
The default is Disable.
6. Use BPDU Guard to specify whether the BPDU guard feature is enabled or disabled.
The
default is Disable. The STP BPDU guard allows a network administrator to enforce the STP
domain borders and keep the active topology be 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 an administrative disable of the port.
7. Use BPDU Filter to specify whether the BPDU Filter feature is enabled or disabled.
The
default is Disable. 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.
8. Click Apply to send the updated configuration to the switch. Configuration changes take
ef
fect immediately.
9. Click Cancel to cancel the configuration on the screen and reset the data on the screen to
the latest value of the switch.
