Enabling Ip Header Compression - HPE FlexNetwork MSR series Configuration Manual

Step
3. Configure the local end to
reject PFC requests received
from the peer.

Enabling IP header compression

IP header compression (IPHC) compresses packet headers to speed up packet transmission. IPHC
is often used for voice communications over low-speed links.
IPHC provides the following compression features:
•
RTP header compression—Compresses the IP header, UDP header, and RTP header of an
RTP packet, which have a total length of 40 bytes.
•
TCP header compression—Compresses the IP header and TCP header of a TCP packet,
which have a total length of 40 bytes.
To use IPHC, you must enable it on both sides of a PPP link.
Enabling or disabling IPHC on a VT, dialer, or ISDN interface does not immediately take effect. You
must execute the shutdown and undo shutdown commands on the interface or the bound physical
interface to apply the new setting.
After you enable IPHC, you can configure the maximum number of connections for RTP or TCP
header compression. The configuration takes effect after you execute the shutdown and undo
shutdown command on the interface. The configuration is removed after IPHC is disabled.
To configure IPHC:
Step
1. Enter system view.
2. Enter interface view.
3. Enable IP header compression.
4. Set the maximum number of
connections for which an interface

By default, the device accepts
PFC requests received from the
peer, and performs PFC on
frames sent to the peer.
