Parameter number: The maximum connection number of TCP header compression. The value ranges from 3 to 256.

Description Use the ppp compression iphc tcp-connections command to configure the maximum number of connections in TCP header compression.

Use the undo ppp compression iphc tcp-connections command to restore the default value, which is 16.

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

pppcompression 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 takes effect 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.

Example # Set the number of compression-enabled TCP connections to 10 on interface Serial 1/0.
