Enabling an IPHC Profile on an Interface
This section describes how to enable an IP header compression (IPHC) profile on an interface by
attaching the profile directly to the interface.
SUMMARY STEPS
To configure to enable an IPHC profile on an interface, perform the following steps.
1. config
2. interface type interface-path-id
3. encapsulation ppp
4. ipv4 iphc profile profile-name [mode service-policy]
5. service policy input | output | type service-policy-name
6. commit
DETAILED STEPS
Command or Action Purpose
Step 1
config
Example:
RP/0/0RSP0/CPU0:router# configure
Enters global configuration mode.
Step 2
interface type interface-path-id
Example:
RP/0/0RSP0/CPU0:router(config)# interface serial
0/1/0/1
Specifies the interface.
Note Use the show interfaces command to see a list
of all interfaces currently configured on the
router.
For more information about the syntax for the router,
use the question mark (?) online help function.
Step 3
encapsulation {hdlc | ppp | frame-relay | mfr}
Example:
RP/0/0RSP0/CPU0:router(config-if)# encapsulation
ppp
Specifies Layer 2 encapsulation for the interface.
Step 4
ipv4 iphc profile profile-name [mode
service-policy]
Example:
RP/0/0RSP0/CPU0:router(config-if)# ipv4 iphc
profile Profile_1
or
RP/0/0RSP0/CPU0:router(config-if)# ipv4 iphc
profile Profile_1 mode service-policy
Attaches an IPHC profile to the interface:
• profile-name—Text name of the IPHC profile to
attach to the interface.
• mode service-policy—Specifies that the IPHC
profile applies only to a QoS service policy.
