Hi everyone,

I'm having an issue with a new network setup here. I have a 6509 with
a Sup720 core switch running in hybrid mode and all 3750's for the
distribution layer. The 6509 and 3750's are connected with fiber and
are dot1q nonegotiate trunks. Trunk links are active and I can ping
devices on Vlan1 (private addressing 192.168.1.x/24). When I do a sh
vlan on one 3750 (all I have online right now) - I get Vlan 1 and Vlan
130. I should also have Vlan 131. The 6509 is configured as a VTP
server and the 3750 is configured as a VTP client - both on the same
Domain. This being said, I cannot ping devices on Vlan 130.

So really, I have two issues going on here.

Any help would be greatly appreciated.

Thanks.

Since it is a new network setup - lose hybrid mode and do not use VTP

Hi Merv,

Thanks for responding. It's been several years since I did a Cisco
implementation. The last time I did it, CatOS was still used on
switches, not IOS. So I'm sorry if my questions are mundane. :)

I turned off VTP. No big deal. Was just trying to make things easier
for myself, but the more I read about VTP, the better turning it off
sounded.

If I turn off hybrid mode, do I just configure everything at the Sup720
level then?

Thanks again.
