Ersin,

The CDP neighbor should show vlan 1 ip address under the show cdp neighbor details.

But:-

1- When you dont have any ip address configured on the vlan 1 ==> You will see the next vlan(ie the vlan which is been configured with ip.)

2- Vlan 1 is shut down at both the ends.

Next Action:

=========

1- Do you have ip address under the vlan 1?

2- show int vlan 1-- does it show you as up state?

Here is the example:-

interface Vlan1
 ip address 1.1.1.2 255.255.255.0
!
interface Vlan2
 ip address 2.2.2.2 255.255.255.0
!

Switch#sh cdp ne de

Device ID: Switch
Entry address(es): 
  IP address : 1.1.1.1 >>>>>>>>>>>>>>>..  Other end ip address.
Platform: cisco 3560, Capabilities: 
Interface: FastEthernet0/1, Port ID (outgoing port): FastEthernet0/1
Holdtime: 175

2- Now I will shut down the vlan 1 both the ends.

Switch(config)#int vlan 1
Switch(config-if)#shut

Switch#sh cdp ne de

Device ID: Switch
Entry address(es): 
  IP address : 2.2.2.1 >>>>>>>>> Now you can see here it has picked vlan 2 ip address.
