OL-26061-03
Step 4
tcp context absolute number-of-contexts
Example:
RP/0/0/CPU0:router(config-iphc-profile)# tcp
context absolute 255
Configures the maximum number of TCP contexts that
are allowed for IPHC on a line card.
Step 5
non-tcp compression
Example:
RP/0/0/CPU0:router(config-iphc-profile)# non-tcp
compression
Enables non-TCP compression in an IPHC profile.
Step 6
non-tcp context absolute number-of-contexts
Example:
RP/0/0/CPU0:router(config-iphc-profile)# non-tcp
context absolute 255
Configures the maximum number of non-TCP contexts
that are allowed for IPHC on a line card.
Step 7
rtp
Example:
RP/0/0/CPU0:router(config-iphc-profile)# rtp
Configures Real Time Protocol (RTP) on the interface.
Step 8
refresh max-period {max-number | infinite}
Example:
RP/0/0/CPU0:router(config-iphc-profile)# refresh
max-period 50
Configures the maximum number of compressed IP
header packets that are exchanged on a link before the
IPHC context is refreshed.
Step 9
refresh rtp
Example:
RP/0/0/CPU0:router(config-iphc-profile)# refresh
rtp
Enables the configured context refresh settings for
RTP packets.
Step 10
feedback disable
Example:
RP/0/0/CPU0:router(config-iphc-profile)# feedback
disable
Disables the IPHC context status feedback messages
on an interface.
