Table of Contents

Enabling PVST

To switch to PVST input the following commands:

console> enable
console# config

For rapid-pvst:

console(config)# spanning-tree mode rapid-pvst

For legacy devices that use PVST:

console(config)# spanning-tree mode pvst
Note: With the latest firmware versions of the switch, both PVST modes support up to 64 VLANs. See the User Guide for your model and firmware version for more information. Dell Support

 
To remove specific VLANs from PVST and include specific VLANs, input the following commands. This example removes VLAN 10 and adds VLAN 20.

console(config)#no spanning-tree vlan 10
console(config)#spanning-tree vlan 20

Setting root bridge priority

The following command sets priority for root bridge selection. This example sets vlan 20 and 30 as priority 4096 and VLAN 40 through 45 as priority 8192.

console(config)# spanning-tree vlan 20,30 priority 4096
console(config)# spanning-tree vlan 40-45 priority 8192

Enabling PortFast

It is recommended to configure any edge ports, ports that go to end devices such as printers, phones, servers, workstations, to be set up as PortFast. A port in PortFast moves directly to the forwarding state when the link comes up without waiting for the forward-time delay.

console(config)#interface te1/0/1
console(config-if)#spanning-tree portfast
Caution: Do not configure PortFast on interfaces that attach to another switch or network device.

Verify Spanning-tree

To review PVST, run the following command. X is replaced with the VLAN ID that you want to check.

console# show spanning-tree vlan X
