You've got a few options. The most basic (and most limited) is using IP RTP
Priority. The will prioritize all RTP traffic on the applied interface. The
best solution (IMHO) is to use LLQ. Low Latency Queueing can be thought of
as CB-WFQ with the added benefit of a priority queue. This is probably
forgot to add one thing you probably already know this but if you
decide to use LLQ for a PPP serial connection (like a t1 or frac t1) you
will want to implement LFI (link fragmentation and interleave). this means
that your config will be implemented on a multilink1 interface rather than
Do you have experience with LLQ and MSFC that you can share?
I configured LLQ but it seems packets are not going to the priority queue:
class-map match-all Priority-Queue
match access-group name TV
!
policy-map Policy
class Priority-Queue
priority 200

i don't see any obvious problems with your configuration. I can, however,
offer a couple of troubleshooting tips. I would start by checking out the
access list (show access-list) to make sure you have packets that qualify.
Second (and this is where I think your problem is), I would lose the
Hi,
I have the following testing setup but it looks like the LLQ
does not work. Can you have a look on it?
