Current STP Mode
(Selectable)
Select the current STP mode using the SPACE bar. You can select one
of the following: IEEE, PVSTP, NONE, and DEC. The default setting

It is recommended that all switches in the network be configured for
the same STP mode setting.

the entire network. Redundant links are placed in standby mode. States
are predetermined to ensure an accelerated failover.

to a different VLAN.
NONE = Spanning tree is not enabled.
DEC = DEC spanning tree protocol.
