Configuring HDLC compression

The STAC-LZ compression compresses the payload of packets on an HDLC link. Because it does
not rely on history packet information, it can achieve a smaller compression ratio. The STAC-LZ
compression increases data transmission efficiency on low-speed links, saves network bandwidth,
and reduces network load.
To configure HDLC compression:
Step
Enter system view.
1.
Enter interface view.
2.
Enable HDLC encapsulation
3.
on the interface.
Enable HDLC compression.
4.

Displaying and maintaining HDLC

Task
Display the HDLC compression
statistics.
Clear the HDLC compression
statistics.
Use the display interface command to display the configuration result.
Use the reset counters interface command to clear the traffic statistics of an HDLC interface and
restart traffic statistics collecting on the HDLC interface.
