Viewing Queue Parameters
Problem
You want to see how queuing is configured on an interface.
Solution
Cisco provides several useful commands for looking at an interface’s queuing configuration and performance. The first of these is the show queue command:
Router#show queueInput queue: 0/75/105/0 (size/max/drops/flushes); Total output drops: 0 Queuing strategy: weighted fair Output queue: 0/1000/96/0 (size/max total/threshold/drops) Conversations 0/1/128 (active/max active/max total) Reserved Conversations 0/0 (allocated/max allocated) Available Bandwidth 75000 kilobits/sec Router#FastEthernet0/0
Use the show queuing command to look the router’s queuing configuration in general:
Router#show queuing
Current fair queue configuration:
Interface Discard Dynamic Reserved Link Priority

Router#Discussion
The show queue and show queuing commands augment the show interface output, which also shows important queuing information:
Router#show interfaceFastEthernet0/0 is up, line protocol is up Hardware is AmdFE, address is 0001.9670.b780 (bia 0001.9670.b780) MTU 1500 ...FastEthernet0/0
