Hi, I have the following testing setup but it looks like the LLQ does not work. Can you have a look on it? When the 256k link was congested. Why I ping the prec. 5 packet behind the 256k line it only have the same response time with default ping? 128k--- FR 256k Attached 256k router configu

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 "matc

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

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 w

Hi, If I want to set the voice traffic have high priority and the rest will use fair queue, which cisco queuing method can achieve it? The hardware is 17xx or 26xx. Thanks. It looks like the LLQ or CBWFQ will have guaranteed bandwidth feature during congestion but seems not the solution I am look
