530 CHAPTER 32: PPP LINK EFFICIENCY MECHANISM CONFIGURATION COMMANDS
Use the undo ppp compression stac-lzs command 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-lzs
option 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-lzs command.
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.
