packets for RTP session setup will also be allowed of header compression. If IP 
header compression is disallowed, however, the TCP packets for RTP session setup 
will also be disallowed of header compression. 

The user must configure IP header compression at the endpoints of a link.

Perform the following in the Interface View. 

This command can delete the invalid IP/TCP header compression or decompression 
context storage table and clear statistic information of IP/TCP header compression.

Perform the following in the System View.

Parameters 

 and 

 indicate interface type and 

number respectively. The parameter 

 is the combination of 

interface type and number. Storage entries of TCP header compression on all 
interfaces will be cleared when the interface is not specified.

The following command is used to configure the connection number of TCP 
compression mode. 

Perform the following in the Interface View. Configuring connection number of 
TCP compression mode 

The parameter 

 indicates the maximum connection number (from 3 to 256) 

of TCP compression mode on the interface. It is 16 by default. 

The following command is used to configure the connection number of IP Header 
Compression.
