Cisco routers may not maintain the same queue numbers when a reboot occurs. This means that TotalView’s QueueVision™ may not show any history for the previous queues. This can be fixed with the following Cisco IOS commands:

Router> enable

Router# configure terminal

Router(config)# snmp-server ifindex persist

Router(config)# snmp mib persist cbqos

Router(config)# end

Router# write mib-data

The above process will create persistence of interface ifIndexes and Class-based QoS queueing information.
