250 ● ppp compression iphc tcp-connections 3Com Router 5000 Family and Router 6000 Family
Command Reference
ppp compression iphc tcp-connections
Purpose Use the ppp compression iphc tcp-connections command to configure
the connection number of TCP compression mode.
Use the undo ppp compression iphc tcp-connections command to
restore the default connection number of TCP compression mode.
Syntax ppp compression iphc tcp-connections number
undo ppp compression iphc tcp-connections
Parameters number
The maximum connection number (from 3 to 256) of
TCP compression mode on the interface.
If no value is specified, the default
number is 16.
Example Set the number of compression-enabled TCP connections to 10 on interface
serial0/0/0.

■ Interface view
Description TCP is connection oriented; the number of TCP connections that a link can
accommodate is relatively large. The use of compression however requires the router
to maintain some information for each connection when compressing headers. To
restrict the memory load generated by compression, you can use the
ppp
compression iphc tcp-connections
command to limit the number of
compression-enabled TCP connections to three for example. The packets on the
fourth TCP connection are not compressed as a result.
The configuration can become valid on an interface only after you perform the
shutdown and then the undo shutdown operations on the interface. If the
configuration is for an MP bundle, you should perform the operations on all MP
member interfaces.
