Want to make switch root for STP, command not available

  • 772

I want to make a certain switch in the network root, but all I remember is the command "set spantree root vlan-id"

Sadly, the "set" command is not available on this switch. How do I proceed?

EDIT: I think I did it with the following command, in config mode:

spanning-tree vlan <number> root primary

Sadly, I have no idea how to confirm this. That becomes the question now.

    1(Enter global configuration mode): configure terminal

    2(change priority): spanning-tree vlan priority primary

    if you have problem try

    (number priority): (config)#spanning-tree vlan vlan-id priority 24576

    (disable uplinkfast, UplinkFast cannot be enabled on VLANs that have been configured with a switch priority): (config)#no spanning-tree uplinkfast
