I have a 2911 that has had a QOS policy on it for about a year.
About a week now I have noticed that the traffic is no longer being tagged as per the QOS assigned to the port.
It is setting many items to default when I am assigning an EF or other rating to them .
If I take the QOS off the port it will pass the incoming QOS through.
I have 5 other 2911s with the same QOS on them and they are all working correctly.
And I went through and compared configs to verify.
One example is our Video traffic we call ZOOM. It is always on port 8801 or 8802
So Acl is
ip access-list extended zoom
permit udp any any eq 8801
permit udp any any eq 8802
deny udp any any
Class map is
class-map match-any video
match protocol h323
match access-group name telemed
match access-group name zoom
set dscp cs4
And I do assign the service-policy output to the needed port.
I am planning a reboot of the router when Time allows.
