With CBWFQ, unlike WFQ, preference is given based on packet classification. The CBWFQ algorithm determines this preference based on the bandwidth command given to each class in the class map. So, in general, packets in a class with a higher bandwidth will go before packets from a lower bandwidth class because that queue is being serviced more often. This will always be the case for a priority queue.
This is true of a priority queue which is configured using the "priority" command as opposed to the "bandwidth" command. In this case, packets in the priority queue will always be sent before other packets. With CBWFQ, the higher bandwidth queue will simply be serviced more often. In some cases, this means that these packets will be sent before others, but not always. In either case, this does create delay for packets in a lower bandwidth class or packets not in the priority queue. When certain packets are given priority treatment either by way of the priority queue or by way of assigning them to a higher bandwidth class, other packets suffer.
I'm not able to access my old voice mail messages all of a sudden. The recording says something like 'the message is currently not available'. This has never happened before in all the years I have been using this system. I have t...
If you have 2 ISR routers, one acting as Failover, do we need to have both the same number of SRST licenses on the 2 routers?
No. You will only need the SRST licenses on the primary router. Because this feature...
