Important
To configure the system to enable RoHC header compression to IP headers:
• Enable RoHC header compression by applying the example configuration in
Compression for PPP, on page 66
.
• Verify your RoHC header compression configuration by following the steps in
Compression Configuration, on page 66
.
• Save your configuration to flash memory, an external memory device, and/or a network location using
the Exec mode command save configuration. For additional information on how to verify and save
configuration files, refer to the System Administration Guide and the Command Line Interface Reference.

Enabling RoHC Header Compression for PPP
Use the following example to enable the RoHC over PPP:
configure
context
<
ctxt_name
>
subscriber name
<
subs_name
>
ip header-compression RoHC [ any [ mode { optimistic | reliable | unidirectional }
] | cid-mode { { large | small } [ marked-flows-only | max-cid | max-hdr
<
value
>
| mrru
<
value
>
] } |
marked flows-only | max-hdr
<
value
> | mrru <
value
>
| downlink | uplink ] }
+
end
Notes:
• <ctxt_name> is the system context in which you wish to configure the subscriber profile. Typically this
is an AAA context.
• <subs_name> is the name of the subscriber in the current context that you want to enable RoHC header
compression for.
• Refer to the Subscriber Configuration Mode Commands chapter in Command Line Interface Reference
for more details on this command and its options.
Verifying the Header Compression Configuration
These instructions are used to verify the header compression configuration.
Verify that your header compression configurations for subscriber by entering the following command in Exec Mode in
specific context:
show subscriber configuration username subs_name
The output of this command is a concise listing of subscriber parameter settings as configured.
