We're changing our edge switches from vlan 1 flat network to layer 2 trunk switches.
1 trunk for data 1 for voice.
New native vlan is 555.
Since starting this, the APs are not displaying any CDP or connected users in WCS.
Vlan 1 is being trunked.
WCS and WISM are using ver 7.
Are the APs connected to trunk ports or access mode?
If trunking is not needed on AP switchport, can you change to access-mode?
I read, there are issues on CDP when AP is connected to trunk port and native vlan is not 1.
Access mode on switchport would fix this.
Have good day.
Try refressing the configurations from the controllers and then try the CDP..
