Item
Description
State
Enable/disable the STP on the switch.
Operation Mode
Specify the STP operation mode.
 STP: Enable the Spanning Tree (STP) operation.
 RSTP: Enable the Rapid Spanning Tree (RSTP) operation.
 MSTP: Enable the Multiple Spanning Tree (MSTP) operation.
Path Cost
Specify the path cost method.
 Long: Specifies that the default port path costs are within the
range: 1-200,000,000.
 Short: Specifies that the default port path costs are within the
range: 1-65,535.
BPDU Handling
Specify the BPDU forward method when the STP is disabled.
 Filtering: Filter the BPDU when STP is disabled.
 Flooding: Flood the BPDU when STP is disabled.
Priority
Specify the bridge priority. The valid range is from 0 to 61440, and the
value should be the multiple of 4096. It ensures the probability that the
switch is selected as the root bridge, and the lower value has the higher
priority for the switch to be selected as the root bridge of the topology.
Hello Time
Specify the STP hello time in second to broadcast its hello message to
other bridges by Designated Ports. Its valid range is from 1 to 10
seconds.
Max Age
Specify the time interval in seconds for a switch to wait the
configuration messages, without attempting to redefine its own
configuration.
Forward Delay
Specify the STP forward delay time, which is the amount of time that a
port remains in the Listening and Learning states before it enters the
Forwarding state. Its valid range is from 4 to 10 seconds.
TX Hold Count
Specify the tx-hold-count used to limit the maximum numbers of
packets transmission per second. The valid range is from 1 to 10.
Region Name
The MSTP instance name. Its maximum length is 32 characters. The
default value is the MAC address of the switch.
Revision
The MSTP revision number. Its valid rage is from 0 to 65535.
Max Hop
Specify the number of hops in an MSTP region before the BPDU is
discarded. The valid range is 1 to 40.
Operational Status
Bridge Identifier
Bridge identifier of the switch.
Designated Root
Identifier
Bridge identifier of the designated root bridge.
Root Port
Operational root port of the switch.
Root Path Cost
Operational root path cost.
Topology Change
Count
Numbers of the topology changes.
