Just started to investigate a medium/large network setup where it seems all of the LWAPs are connected to switchports configured as trunks and all of the LWAPs are in local mode. Each switchport is configured like this...   interface GigabitEthernet2/0/25 description Access Point Port switchport trunk native vlan 20 switchport mode trunk switchport nonegotiate srr-queue bandwidth share 10 10 60 20 queue-set 2 priority-queue out mls qos trust cos macro description cisco-wireless auto qos voip trust spanning-tree bpduguard enable end   Trunking on the switchport is shown below, potentially a lot of frames getting sent to the APs that will not be processed because of the capwap tunnels   Port Mode Encapsulation Status Native vlan Gi2/0/25 on 802.1q trunking 20   Port Vlans allowed on trunk Gi2/0/25 1-4094   Port Vlans allowed and active in management domain Gi2/0/25 1-4,7-9,12-13,15-17,20,110,120,500-501,999   Port Vlans in spanning tree forwarding state and not pruned Gi2/0/25 1-4,7-9,12-13,15-17,20,110,120,500-501,999   Given this is a pretty busy network, there are configurations on each of these ports that may not be needed, and each AP is going to drop tagged frames, is it worth going around and fixing each of these ports? There are about 100 of them. The wireless infrastructure works, seems to perform okay, but wondering if I can increase performance/reliability by getting a better port config on each of these. Is that cisco-wireless macro typically used for APs supporting voice? What is the best practice switchport configuration for an AP in local mode supporting voice/Qos?  ... View more

Recently, we disabled legacy data rates on a 5508 running 8.5.151.0, and then these messages popped up in the logs,   %APF-3-CHECK_SUPP_RATES_FAILED: [PA]apf_utils.c:411 Could not check supported rates. Missing Supported Rate. Length :0. Mobile MAC: xx:xx:xx:xx:xx:xx.   for about 8 mac addresses and reoccurred every hour, so we restored the data rates to the previous settings and the messages disappeared, but we never had any user complaints.   Now with the rates restored, the messages are gone but when I search on these 8 mac addresses not one of them returns anything from show client detail. So, these phantom mac addresess that we never got user complaints about but had logged messages for don't show up as connected clients even though the log messages have stopped.    I do not know how to reconcile or explain this result.  ...
