Examples
Creating an RPVST instance for a list of VLANs and configuring various time parameters:
switch# config switch(config)# spanning-tree vlan 2-5 switch(config)# spanning-tree vlan 2-5 hello-time 5 switch(config)# spanning-tree vlan 5 max-age 10 switch(config)# spanning-tree vlan 2-5 forward-delay 25 switch(config)# spanning-tree vlan 2-5 priority 5
Removing an RPVST instance for a list of VLANs and setting various time parameters to the default:
switch# config switch(config)# no spanning-tree vlan 2-5 switch(config)# no spanning-tree vlan 2-5 hello-time switch(config)# no spanning-tree vlan 2-5 forward-time switch(config)# no spanning-tree vlan 2-5 max-age switch(config)# no spanning-tree vlan 2-5 priority
