I'm transferring a gig connection from a 7206 router to a 7604 router (IOS = 12.2(33)SRB2) to get more throughput. The configuration has standard LLQ QOS classes for voice and video and class-default.
When I copy over the classes and policy-maps from the 7206 to the 7604 and apply them to a SPA-2GE interface, the IOS complains that the interface cannot do fair-queueing. Here are the class maps and policy map from the 7206:
class-map match-any Call-Control
match ip dscp cs3
class-map match-any Video
match ip dscp af41
class-map match-any Voice
match ip dscp ef
fair-queue <----- I had to remove this
I like how fair-queueing worked in class-default on the 7206 and would like the same on the 7604, but it seems like it can't do that.
Is there another way to do this, or is this something that is a limitation of the hardware, or will future IOS releases incorporate the feature?
