Policy map for a Cisco AP on a 3750-X switch port

[resbanknet]

Can anyone advise on a good default policy-map for a Cisco AP on a 3750-X switchport?  I am particularly concerned about ensuring that CAPWAP traffic is not dropped on a pretty busy switch.  Also any other advice about the switchport configuration?  I did configure "mls qos trust dscp" on both the AP interfaces and the trunk uplink but I still have issues where an AP will every so often just lose its connection to the WLC.

Thanks

Hello,

CAPWAP uses UDP ports 5246 and 5247, you could try the service policy below. Not sure if that solves your problem though...

access-list 101 permit udp any any eq 5246
access-list 101 permit udp any any eq 5247
!
class-map CAPWAP_CLASS
match access-group 101
!
policy-map CAPWAP_POLICY
class CAPWAP_CLASS
set dscp cs7
!
interface GigabitEthernet0/7
service-policy input CAPWAP_POLICY
