Re: VTP Server and Transparent

Good Afternoon Don,

I would do a show vlan brief:

Than will give you the list of Vlans on the switch, from that output
you should be able to configure. Please let me know if that does not
work for you.

I also answered for Narbik in previous response, you could have a
server switch, due to vague question could have assumed that there is
a server with a virtual switch on network with higher prioirty and is
acting as root for vlans, you can configure the port, so that it will
not accept superior BPDUs from the switch acting as root.

Regards,
John
