63.3.1 STP and RSTP Command Examples

This example configures STP in the following ways:
Enables STP on the OLT.
1
Sets the bridge priority of the OLT to 0.
2
Sets the Hello Time to 4, Maximum Age to 20 and Forward Delay to 15.
3
Enables STP on port 2 (on the uplink card in slot 3) with a path cost of 150.
4
Sets the priority for port 2 to 20.
5
OLT2406(config)# spanning-tree
OLT2406(config)# spanning-tree priority 0
OLT2406(config)# spanning-tree hello-time 4 maximum-age 20 forward-delay
15
OLT2406(config)# spanning-tree msc-1-2 path-cost 150
OLT2406(config)# spanning-tree msc-1-2 priority 20
This example shows the current STP settings.
