Troubleshooting Commands

show queueing and show queue
To verify the configuration and operation of the queuing system, you can
issue the following two commands:
show queueing [fair | priority | custom]
show queue [interface-type interface-number]
Results from these commands on Router C can be seen as follows.
Because weighted fair queuing is the only type of queuing that has been
enabled on this router, it wasn't necessary to issue the optional command of
fair
, custom, or priority.
Router_C#show queueing
Current fair queue configuration:
Interface Discard Dynamic Reserved
threshold queue count queue count
Serial0 96 256 0
Serial1 64 256 0
Current priority queue configuration:
Current custom queue configuration:
Current RED queue configuration:
Router_C#
This command shows that weighted fair queuing is enabled on both serial
interfaces, and that the discard threshold for Serial 0 was changed from 64
to 96. There's a maximum of 256 dynamic queues for both interfaces--the
default value. The lines following the interface information are empty
because their corresponding queuing algorithms aren't configured yet.
The next command displays more detailed information pertaining to the
specified interface:
Router_C#show queue serial0
Input queue: 0/75/0 (size/max/drops); Total output drops:
0
Queueing strategy: weighted fair
Output queue: 0/1000/96/0 (size/max total/threshold/
drops)
Conversations 0/1/256 (active/max active/max total)
Reserved Conversations 0/0 (allocated/max allocated)
