For the sake of me I can't figure this out. I have a NM-ESW 16 port in a 2811 with IOS 12.4(11)XJ4. I need to connect IP phones and PC behind them in the classic access + voice VLAN configuration.
What happens, is that as soon the voice vlan is configured on the NM-ESW interface, I loose communication to with the access vlan. See how all the mac-address related toVLAN 2 disapperas.
This happens either whit an IP phone connected to the NM-ESW and a singlePC behing the phone, or a non-cisco switch connected to the NM-ESW.
See the attached log and configuration.
I've tried anything, cdp enable/disable, changing vlan, removing the BVI that I need to wireless, no change. I would really use some help here before going to the TAC.
