Example
# Enable IP header compression on interface Dialer1.
[H3C-Dialer1] ppp compression iphc
1.2.8 ppp compression iphc rtp-connections
Syntax
ppp compression iphc rtp-connections number
undo ppp compression iphc rtp-connections
View
Interface view
Parameter
number
: The maximum connection number (from 3 to 1000) of IP Header Compression
mode on the interface. By default, the
number
is 16.
Description
Use the
ppp compression iphc rtp-connections
command to designate the
connections number of IP Header Compression allowed on one interface.
Use the
undo ppp compression iphc rtp-connections
command to cancel the
configuration and restore the default value.
RTP is connection oriented; the number of RTP connections that a link can
accommodate is relatively large. The use of compression however requires the system
to maintain some information for each connection when compressing headers. To
restrict the memory load generated by compression, you can use the
ppp
compression iphc rtp-connections
command to limit the number of
compression-enabled RTP connections to three for example. The packets on the fourth
RTP connection are not compressed as a result.
The configuration will take effect after commands
shutdown
and
undo shutdown
have been executed on the interface. When configuring MP, commands
shutdown
and
undo shutdown
must be executed on all MPs.
Example
# Set the number of compression-enabled RTP connections to 10 on interface Dialer1.
[H3C-Dialer1] ppp compression iphc rtp-connections 10
