Have an odd issue getting LAN communicating using a particulcar vlan. I will show the setup
ISP(VPN)==========>2811 Gateway=======>2960NONPOE=======> 2950 (root)========> 2960POE=======>WLC4400(10.151.220.146)
I have sub interface for vlan 20 on 2811, it's active etc:
encapsulation dot1Q 20
ip address 10.220.252.145 255.255.255.240
encapsulation dot1Q 100
ip address 10.220.252.254 255.255.255.192
ip wccp 61 redirect in
I am then trunking everything from 2960NONPOE through to the WLC4400. I already have another vlan 100 which is works fine and used for management of each of all devices except WLC4400. However when I configure the address 10.220.252.146 on the WLC the router/gateway 2811 with address 10.220.252.145 doesn't communicate with it.
The 2960POE can ping 10.220.252.145 with it's vlan 100 address which is 10.151.220.245; however it can't communicate with the WLC4400s vlan 20 address 10..220.252.146 even though the address shows on the 2960POE when using "show cdp neighbour detail"
When I put an SVi for vlan 20 on 2960POE it can ping the WLC 10.220.252.146 but instead can't communicate with vlan20 gateway 10.220.252.145 which it could before even if I use "ping 10.220.252.145 source interface vlan 100 (which was the management address used previously to communicate with it.
If I put SVI from vlan 20 on 2960NONPOE then I can ping the router but not the WLC4400.
There are no vlans being blocked by trunk.
The spanning tree root bridge for all vlans is the 2950; could this be the problem? I ask this because this whole setup was working at one stage but stopped working when someone went on site and not sure what has changed since!
Thanks for your help
