530CHAPTER 32: PPP LINK EFFICIENCY MECHANISM CONFIGURATION COMMANDS

Use the undo ppp compression stac-lzscommand to disable STAC-LZS compression on the current interface.

By default, this compression is disabled.

STAC-LZS compression is supported on the current version of system. You can configure STAC-LZS compression on an interface to reduce size of data frames through lossless compression. However, as this can increase the load on the device, you are recommended to disable the function when the device is heavily loaded.

Note that STAC-LZS compression takes effect on a PPP link only when the stac-lzsoption is configured on both ends of the link. Currently, outbound expedite forwarding is not applicable on links with Stac-LZS compression enabled. So, it is recommended that you disable outbound fast forwarding before execute the ppp compression stac-lzscommand.

Note that:

■If the configuration is applied on VT and Dialer interfaces, ISDN and asynchronous dialer interfaces, the configuration takes effect only after you shut down and then bring up the interfaces.

■If the configuration is applied on a MP bundle, you need to shut down and then bring up all the member interfaces of the MP bundle for the configuration to take effect.

Example # Enable STAC-LZS compression on interface Serial 2/0.

<Sysname> system-view

[Sysname] interface serial 2/0

[Sysname-Serial2/0] ppp compression stac-lzs

ppp mp lfi

Syntax ppp mp lfi

undo ppp mp lfi

View Virtual template interface view, MP-group interface view, dialer interface view

Parameter None

Description Use the ppp mp lfi command to enable link fragmentation and interleaving (LFI) on the interface.

Use the undo ppp mp lfi command to disable the function.

By default, LFI is disabled.

Example # Enable LFI on Virtual-Template1.
