When IPHC TCP header compression is applied on an MP link, the compression 
is performed on the VA (virtual access) interfaces. In this case, you can check 
the compression information on MP templates, such as VT or Dialer.

■

When IPHC TCP header compression is applied on a normal PPP link, the 
compression is performed on the physical link. In this case, you can check the 
compression information on the physical interfaces only.
