Now that WFQ is configured on the router’s serial 0 interface, let’s see what it’s doing. 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 next. Since WFQ is the only type
of queuing that’s been enabled on this router, it isn’t necessary to issue the optional commands
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 WFQ 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 haven’t been 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)
This command displays the input queue information, which is the current size of the queue,
the maximum size of the queue, and the number of conversations that have been dropped. The
queuing strategy is defined as weighted fair, or WFQ. The output queue (usually the one with
the most activity) defines the current size, the maximum total number of output queue entries, the
number of conversations per queue, and the number of conversations dropped. The conversations
section represents the number of conversations in the queue. The active number describes the
number of current active conversations. The max active keeps a record of the maximum number
of active conversations at any one time, and max total gives the total number of all conversations
possible within the queue. Reserved queues are also displayed with the current number allocated
and maximum number of allocated queues.
