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:
