Cisco Network Analysis Module Chapter 6 Medianet Management and Visibility Design Considerations Router Show Policy Map Commands me-eastny-3-2#show platform port-asic stats drop gig 2/0/24 Interface Gi2/0/24 TxQueue Drop Statistics Queue 0 Weight 0 Frames 0 Weight 1 Frames 0 Weight 2 Frames 0 Queue 1 Weight 0 Frames 0 Weight 1 Frames 0 Weight 2 Frames 0 Queue 2 Weight 0 Frames 0 Weight 1 Frames 0 Weight 2 Frames 0 Queue 3 Weight 0 Frames 0 Weight 1 Frames 0 Weight 2 Frames 0 Note that when the session 2 command is run, the command prompt changed from me-eastny-3 to me-eastny-3-2, indicating that a session to member switch #2 has been established. After the session is established to the remote switch, the show platform port-asic stats drop command can be run on an interface, such as GigabitEthernet 2/0/24 shown in the example above, to obtain the drop statistics per queue on the port. For Cisco routers, the mapping of traffic classes to egress queues over WAN interfaces is accomplished via an egress policy map applied to the interface, in the same manner as the Cisco Catalyst 4500 with a Sup-6E supervisor. Again, the policy map can be viewed through the show policy-map interface command. Example 6-27 shows the output from a Cisco ASR 1000 Series router with a OC-48 packet-over-SONET (POS) interface. Selected areas for discussion have been highlighted in bold.
