I am deploying QOS using MQC approach.

1st site look fines and working, I've applied my policy on Router physical interface (facing MPLS clould) and "qos pre-classify"command on Router tunnel interface & crypto map. Physical interface queuing method change from "fifo" to CBWFQ which is correct.

2nd, 3rd & 4th Site, same QOS setup, same QOS approach, unfortunately the queuing method is still the same "fifo" when I do "show  interface f0/0/0". The only difference between site 1 & site 2-4 is the Router model and IOS version.

1st Site: 2851 Router (IOS Version 12.24+)

2nd-4th Site: 3725 Router (IOS Version 12.4)

Aditional Info:


2. WAN Setup: Using IPSec transport mode with encrypted GRE tunnel

Having mention the above, may I ask your comment on this.

Hope to hear from you soon.

MQC applied to a tunnel interface won't change the queueing on the physical interface.

You may want to check for commands like fair-queue under the physical interface for queueing mechanism - this enables WFQ

Hi Edison,

Thanks for the reply, appreciate it.

My setup is like this.

Physical Interface (F0/0/0 Facing MPLS Cloud) = service-policy output WAN.Edge

Tunnel Interface (Tunnel 1) = qos pre-classify

crypto map test 10 ipsec-isakmp = qos pre-classify

I'm bit confused its because Site 1 Physical interface queueing has change while Site 2 to Site 4 did not.

Purely cosmetic since you have different hardware. The service-policy will dictate how the packets will be queued, not the physical interface queueing status.

Can you copy and paste the physical interface config from all routers?
