Usage Guidelines

Usage Scenario

If a dialer interface receives a packet but the call connection is not established, the dialer interface discards the packet. However, if a buffer queue is configured on the dialer interface, the dialer interface stores the packet in the buffer, and sends the packet after the call connection is established.


  • If you run the dialer queue-length command multiple times in the same view, only the latest configuration takes effect.
  • If the buffer queue is long, the interface discards less packets, but a lot of system resources will be occupied. It is recommended that the queue length value be equal to or smaller than 20.


# Set the buffer queue length on Dialer1 to 10.
