I am trying to get a 2106 controller (latest firmware) and 3 1252 access points in to our network. We have 3560 core switches with a few VLAN's. I can set it all up fine on its own with my laptop on the WAC itself, but plugging in to a swtich port in our server VLAN doesn't work at all. Its not reachable via ping, telnet, HTTP.
I have since got it kind of working. I set up a switchport in trunk mode, and I ALSO HAD TO TAG the management/ap interfaces. This is the only way I can telnet/HTTP in to the WAC. BUT, I can only seem to do so now from within that server VLAN. I can't reach the device from our client VLAN, nor can I reach from the WAC to our client VLAN. Even with the trunkport set, if I set the interfaces on the WAC to untagged, I can't do anything on the WAC at all! Any ideas what I am missing?
Make sure you have all the vlans defined on the switches. Make sure all switch to switch connections are set to trunk. Each vlan will need a layer 3 interface also. the management and ap-manager should be on the same vlan and the dot1q trunk port should be set to native vlan X. X being the vlan the management and ap-manager ip is on. On the WLC, you should set the vlan tag "0" untagged. That should get you going.
Place the AP's on the same subnet as the management and ap-manager and make sure there is a dhcp scope for that subnet so the ap's can obtain an ip address and be able to join the WLC. Then you can move the ap to another subnet if you wish.
