About this task
Use this task to configure Spanning Tree settings.
Procedure
-
For STP Mode, select one of the
following:
- STP: Uses a single spanning tree without regard
to VLANs. After convergence, only the root bridge sends configuration BPDUs,
and other switches only relay those BPDUs.
- RSTP (Rapid STP): Uses a single spanning tree
without regard to VLANs. After convergence, all switches send BPDUs every
two seconds in the event of a physical link failure.
- MSTP (Multiple STP): Can map a group of VLANs
into a single multiple spanning tree instance (MSTI). MSTP uses BPDUs to
exchange information between spanning-tree compatible devices, to prevent
loops in each MSTI by selecting active and blocked paths.
-
Select an STP Bridge
Priority from the drop-down list.
Every switch taking part in
spanning tree has a bridge priority. The switch with the lowest priority becomes
the root bridge. If there's a tie, the switch with the lowest bridge ID number
wins. The ID number is typically derived from a MAC address on the
switch.
-
Set the following STP Timers
parameters:
Forward
Delay: The time the switch spends in the listening and
learning state.
Max
Age: The maximum time before a bridge port saves its
configuration BPDU information.
