NOTE: The Global STP status default was 'Ebable' in previous software versions and was
changed to 'Disable'. Please note that if STP enabled is the required state, you should enable
STP via the WEB GUI or the CLI.
NOTE: In case of STP loopback the port will be shutdown, the port will be activated after the
loopback is removed

Description
Specifies the selected spanning tree instance device priority. The field range is 0-65535.
The default value is 32768.
Set to ensure old information is not circulated endlessly through redundant paths in the
network, preventing the effective propagation of the new information. Set by the Root
Bridge, this value aids in determining that the switch has spanning tree configuration
values consistent with other devices on the bridged LAN. If the value ages out and a
BPDU has still not been received from the Root Bridge, the switch will start sending its
own BPDU to all other switches for permission to become the Root Bridge. If your
switch has the lowest Bridge Identifier, it will become the Root Bridge. The user can
choose between 6 and 40 seconds. The default value is 20.
The interval between two transmissions of BPDU packets sent by the Root Bridge to
indicate to all other switches that it is indeed the Root Bridge. The default value is 2.
Defines the time any port on the switch is in the listening state while moving from the
blocking state to learning state and then to the forwarding state. The default value is 15.
Specifies the total number of hops that occur before the BPDU is discarded. Once the
BPDU is discarded, the port information is aged out. The possible field range is 1-20.
The field default is 20 hops.
. The Spanning Tree Global Parameters are defined, and the device is updated.
