No. There is a single priority queue (LLQ). You can map multiple classes
into this single queue, thus expanding its size, but that particular single
queue is handled in a FIFO manner. Just before everything else.

Subject: RE: Sort of OT: Hardware Queues on Serial Interfaces
Hmm... then I misunderstood.
Let me refine the question then:
Is it possible to prioritize different types of traffic *WITHIN* the
priority queue?
Say for example you've got calls that make money and calls that don't.
Both need strict priority, but can you prioritize one over the other?
For example:
class-map match-all MoneyMaker
match input-interface FastEthernet0/1
!
class-map match-all Admin
match input-interface FastEthernet0/0
!
!
policy-map Calls
class MoneyMaker
priority 2000000
class Admin
priority 500000
Will this service the queue more "often" for the MoneyMaker class than the
Admin class, and more importantly, will it negatively affect either?
It doesn't look or sound like a good idea to me, by I in part need to
understand it, and in part need to counter someone's argument.
Thanks,
GAD
