Parameters
interface-type interface-number: Specifies an interface by its type and number.
|: Filters command output by specifying a regular expression. For more information about regular

Usage guidelines
When IPHC RTP applies to MP links, the associated VA interfaces perform the compression. You can
check the compression information on MP templates, such as VT or dialer interfaces.
When IPHC RTP applies to normal PPP links, physical interfaces perform the compression. You can check
the compression information on the physical interfaces.
