I have 2 switches connected together. A 6500 and a 2916-xl. The connetions passes cdp nei but I can't get an IP connection. The ports on both ends show up and up (actually, connected on the 6509 end). The 2916 end is using port fa0/16 which is on vlan1 in vtp mode transparent and with no vtp domain name that I can find. (BTW: what's the command to see what vtp domain the switch is in on a 2916-xl?) So, I don't thing vtp is an issue. The ports are connected but won't pass IP.

You probably have to go into the vlan database to see that . conf t , vlan-database . you should also be able to see the state of vlan 1 while you are in there . While you are in there , try entering vlan 1 state active and see what happens . Is the port on the 6500 in vlan 1 also ?

it's vlan 100 on the 6509. I have the vlan1 interface on the 2900 set to a vlan100 address. The 2900 is in transparent mode and no vtp domain name; at least I didn't enter one. I know the vlans don't have to match unless the 2 switches are in the same vtp domain; since they aren't, as long as I have the address in the right vlan (vlan 100, in this case), it sould work.

You can use "sh vtp status" the XL switch. On an XL/2950 switch only one L3 Vlan interface can be up/up at any given time(note that this interface is used for management purposes such as ping/telnet only). Check to see if there are any other VLAN interfaces up/up on the XL and if they are shut them down and the VLAN 1 should come up fine

you were right. I have all but one port on vlan2 for my devices. I have the other port on vlan1. I used switchport access vlan 2 on all but one port. I used int vlan 2 to create vlan 2. If I bring down vlan2, vlan1 will come up and work fine. What I don't know is if/when I did shut down vlan2, do the devices on vlan 2 still talk. If they will, all I have to do is shut int vlan 2, rigtht?
