3.4.3 Clearing the Queue-based Statistics

You can use the reset command to clear the queue-based traffic statistics.
Context
To re-collect the queue-based statistics on an interface, you can use the following command in
the user view to clear the previous statistics.
The queue-based statistics cannot be restored after you clear them. So, confirm the action before
you use the command.
Procedure

Issue 01 (2011-07-15)
The command output on different types of boards is different:
– S-series boards
The system allocates the minimum buffer length to each queue on the interface. When
a queue uses up its buffer, it obtains the shared buffer on the interface. By default, the
used length of a queue is the sum of the buffer length of the queue (N) and the shared
buffer length of the interface (M).
After the queue length is set:
– If the queue length is smaller than M, the used queue length is M.
– If the queue length is larger than M, the used queue length is the configured value
that is converted by the system. For example, when the queue length is set to 61442,
the displayed value is 61568.
– E-series boards
By default, the used queue length is the number of bytes of packets buffered in the
queue.
After the queue length is set, the used queue length is the configured value that is
converted by the system. For example, when the queue length is set to 61442, the
displayed value is 61568.
NOTE
G48SBC boards and W series boards do not support the display qos queue length command.
For details about S-series boards, E-series boards, W series boards, and G48SBC boards, see Board
Classification in the Quidway S7700 Smart Routing Switch Hardware Description.
CAUTION
Run the reset qos queue statistics interface interface-type interface-number command to
clear the queue-based traffic statistics on the interface.
