What commands can I use to monitor queueing?
A. Use the following commands to monitor queueing: • show queue {interface}{interface number} – On Cisco IOS platforms other than the Cisco 7500 Series, this command displays the active queues or conversations. If the interface or Virtual Circuit (VC) is not congested, no queues will be listed. On the Cisco 7500 Series, the show queue command is not supported. • show queueing interface interface-number [vc [[vpi/] vci] – This displays the queueing statistics of an interface or a VC. Even when there is no congestion, you will still be able to see some hits here. The reason for this is that process switched packets are always counted regardless of congestion being present. Cisco Express Forwarding (CEF) and fast-switched packets are not being counted unless there is congestion. The legacy queueing mechanisms like Priority Queueing (PQ), Custom Queueing (CQ), and Weighted Fair Queueing (WFQ), will not provide classification statistics.
