display ppp compression iphc
Use
display ppp compression iphc
to display IP header compression (IPHC) statistics.
Syntax
display ppp compression iphc
{
rtp
|
tcp
} [
interface interface-type interface-number
]
Views
Any view
Predefined user roles
network-admin
network-operator
Parameters
rtp
: Displays IPHC RTP header compression statistics.
tcp
: Displays IPHC TCP header compression statistics.
interface interface-type interface-number
: Specifies an interface by its type and number. If you do
not specify this option, the command displays IPHC statistics on all interfaces.
Usage guidelines
When IPHC applies to an MP link:
• If an MP template is used, such as a VT interface or a dialer interface, the associated VA
interface performs IPHC. You can view the compression information on the VA interface.
• If an MP-group interface is used, the MP-group interface performs IPHC. You can view the
compression information on the MP-group interface.
When IPHC applies to a normal PPP link, the physical interface performs IPHC. You can view the
compression information on the physical interface.
