PVSTP Configuration

Hi I'm Fabio.

I'm getting a mistake with PVSTPconfiguration.

Briefly, I want:

1)Swicth A primary root for VLAN 22, 23. Secondary root for VLAN 21

2)Switch B primary root for VLAN 21. Secondary root for VLAN 22, 23

3)I know how to configure primary root and secondary root, but i have some doubts about vlan configurations.

Questions:

A)How i have to set the STP mode for each switch? Transparent? Server? Client?

B)Where i have to create VLAN 21, 22, 23?

Thanks, Fabio.

The answer to question b) depends entirely on what you do in question a).

Do you mean VTP mode rather than STP mode ? A switch can either be a VTP server, client or transparent.

If transparent then you have to configure the vlans on all switches.

If you make switch A or B or both VTP server then you can configure C to be a client and configure the vlans on just one of the switches, either A or B if they are both VTP servers. If you just make A VTP server then configure B & C to be client and then configure the vlans on switch A and they will be propogated to B & C.

Once the vlans are there on all switches then on A -

spanning-tree vlan 22 - 23 root primary

spanning-tree vlan 21 root secondary

on B -

spanning-tree vlan 21 root primary

spanning-tree vlan 22 - 23 root secondary
