Usage guidelines
Before configuring this command, make sure that the queue af command or the queue wfq command
has been configured.
The queue length configured with the queue-length command is deleted when the undo queue af
command or the undo queue wfq command is executed, and vice versa.
The queue length configured with the queue-length command is deleted when random drop is used
using the wred command, and vice versa.
When low-priority services preempt the bandwidth for the AF service, you can increase the queue size for
the AF service.
Examples
# Configure a maximum queue length of 16 and specify tail drop for AF.
<Sysname> system-view
[Sysname] traffic behavior database
