Use this task to enable STP and configure the settings for a switch template.
-
Go to .

Select an existing template, and then select
, or select 
-
From the Configuration menu, select Device
Configuration.
-
Toggle STP (Spanning Tree
Protocol) to ON.
-
Select the STP Mode:
- STP—The initial version of this protocol uses a
single tree without regard to VLAN. After convergence (30-50 seconds),
only the root bridge sends configuration BPDUs (Bridge Protocol Data
Units).
- RSTP (Rapid STP)—Like STP, RSTP uses single tree
without regard to VLAN. After convergence (a few millisecond to 6
seconds), all switches send BPDUs every 2 seconds.
- MSTP (Multiple STP)—Multiple Spanning Tree
Protocol (MSTP) can map a group of VLANs into a single Multiple Spanning
Tree instance (MSTI).
-
Select a Priority for STP
from the drop-down list.
-
Configure the STP Timers:
- Forward Delay—This is the time the switch spends
in the listening and learning state. The default is 15 seconds, and the
range is 4 to 30 seconds.
- Max Age—This is the maximum time period before a
bridge port saves configuration BPDU information. The default is 20
seconds, the range is 6 and 40 seconds.
-
Select SAVE.
Continue configuring the Ethernet port.
