Is "7920 AP CAC" check-box in the WLC required as best practice for the the 7925G phones/voice WLAN?
I find this confusing because different documents says differently. I personally don't think it is because WMM is 802.11e standard and that is enough. In the 7925G deployment guide pg. 52, it says to enable "7920 AP CAC". I wonder if this was brought over from the 7921 phones? Both FastLane and IPExpert workbooks doesn't state to enable it. Another document from Cisco, "Voice Over Wireless LAN (VoWLAN) Troubleshooting Guide" has a checklist of best practice for voice. There is a task in there that states to make sure "7920 Client CAC" is disabled, but not about enabling "7920 AP CAC". I guess in the real world it would be safe to have both WMM and "7920 AP CAC" enabled but in the lab there's a possibility to be marked down for over-configuration. What is your point of view on this? Or is there something that understood wrongly? Thanks. Regards, Jeen chew
