I have the below config:
match protocol rtp
ip address 10.255.255.4 255.255.255.0
ip nhrp authentication UbSmEbK
ip nhrp map 10.255.255.1 126.96.36.199
ip nhrp network-id 255
ip nhrp nhs 10.255.255.1
keepalive 10 3
tunnel source Ethernet0
tunnel destination 188.8.131.52
tunnel key 255
When I tru to apply the policy-map on the tunnel interface (service-policy output QOS) i am getting the following error:
"Low Latency Queueing feature is not supported in user defined class of parent level policy"
I could be wrong but i dont think you could apply a service policy on a tunnel interface for LLQ without shaping!
Instead, you need to apply a hierarchical policy. Create a "child" or lower-level policy that configures a queueing mechanism, such as low latency queueing with the priority command and class-based weighted fair queueing (CBWFQ) with the bandwidth command.
Create a "parent" or top-level policy that applies class-based shaping. Apply the child policy as a command under the parent policy because admission control for the child class is done according to the shaping rate for the parent class.
