- Purple, 4500 points or more
I've got a 3548-XL switch that I'm trying to configure for VTP. I know this switch is really old, so bear with me. I've got the latest and LAST IOS that Cisco came out with.
Configuring vtp on this switch is different first of all. I have to be in vlan database mode before I can configure it. That being said, I have a VTP server already on the network on a 2950 switch. This works good with my other 2950 switch, but the 3500xl won't work, but there's more to it than that.
I configure the following:
vtp domain CISCO
When I get to the enable prompt, I do a show vtp status and my changes are shown. I don't receive vlans from my vtp server. Also, when I reboot (after writing changes) everything goes back to default on this switch for vtp only. (vtp mode is server, null domain, etc.)
Was this a known issue with the 3500s?
I think what is happening is that if the switch cannot find a VTP server then it will not allow itself to be configured as a client.
When you configure it as a client -
1) can you check the trunk status to the VTP server
2) can you check the configuration revision number is less on the 3500XL.
3) Can you check that you aren't using a password
Also when you have the new switch connected just update the vlan database on the VTP server and see if the changes then propogate to the 3500.
