I have a switch at a remote site with no technicians. It is a new switch and a config was placed on it prior to its deployment. The switch was installed and connected to the router with a straight-through to the switches Gi0/1 port from Router-Fa0/0/0 - L2 port).
Here is the relevant switc h config:
vlan 2330
interface FastEthernet0/7
switchport access vlan 2330
switchport mode access
spanning-tree portfast
!
interface FastEthernet0/8
switchport access vlan 2330
switchport mode access
spanning-tree portfast
!
interface GigabitEthernet0/1
!
interface Vlan1
no ip address
shutdown
!
interface Vlan2330
ip address 10.33.13.2 255.255.255.240
!
ip default-gateway 10.33.13.1
ip classless
ip http server
Here is the relevant router config:
interface FastEthernet0/0.3330
encapsulation dot1Q 3330
ip vrf forwarding 3330
ip address 10.33.254.4 255.255.255.192

The router's vlan database mode will not let me do extended vlans so I can't match up the vlans on each side. I can see the switch in sh cdp neigh. I would like to be able to get access to the switch so that I can configure it in a regualr vlan range. Is this possible? Or will I have to drive over 100 miles just to console to the switch?

Thats a problem don't see a way around that.

Hi Aaron,
To configure extended vlans, the vtp mode must be transparent.So, have you tried changing the vtp mode to transparent on the router.

Yes, I have. But you can only configure vlans on the router from vlan database mode. In vlan database mode you cannot use extended vlans.

try using vlan "vlan-id" global configuration command because you cannot create extended vlans from vlan database mode. which router is this?

Try This:
When you connect to router, telnet to switch
ip address 10.33.13.2 first
Switch
config t
int g0/1
switchport trunk native vlan2330
no shut
Router
config t
no vlan10
int fa0/0/0
ip address 172.16.1.1 255.255.255.252
encap dot1q 1 native
no shut
exit
line vty 0 4
exec-timeout 20 0
lockable
private
logging synchronous limit 4000
login local
transport input telnet ssh
exit
wr mem

The problem is that I cannot telnet to the switch from the router or from anywhere. I actually got the extended vlans working by doing an IOS upgrade. So now my fa0/0/0 port looks like this:
interface FastEthernet0/0/0
switchport mode trunk
ip vrf forwarding 3330
and I have an int vlan of:
interface Vlan2330
ip vrf forwarding 3330
ip address 10.33.13.1 255.255.255.240
I still can't connect to it, though. What about getting smoeone to reset the switch to factory defaults? Would that be easier? Could I connect from the router to the switch if the switch has the defaults and a blank config?

also, I can't assign an ip address to a layer 2 port (fa0/0/0)
