IPHC Support for Frame Relay Interfaces
Enabling Header Compression at Sub-Interface Level
To enable the header compression at subinterface level, perform the following required steps:
SUMMARY STEPS
1.
enable
2.
configure terminal
3.
frame-relay ip rtp header-compression
4.
frame-relay ip tcp header-compression
5.
show ip rtp header-compression
6.
show ip tcp header-compression
DETAILED STEPS
Step 5
hw-module slot <slot> ip tcp
compression-connections <maximum number of
connections>
Example:
Router# configure terminal
Router(config)# hw-module slot 2 ip tcp
compression-connections 1000
Configures the maximum number of TCP contexts per line
card. The valid range for maximum number of connections
is 1 to 64000. Normal default value is 0 for this parameter.
card. The valid range for maximum number of connections
is 1 to 64000. Normal default value is 0 for this parameter.
Step 6
hw-module slot <slot> ip rtp
compression-connections <maximum number of
connections>
Example:
Router# configure terminal
Router(config)# hw-module slot 2 ip rtp
compression-connections 32760
Configures the maximum number of non-TCP (cRTP)
contexts per line card. The valid range for maximum
number of connections is 1 to 32768. Normal default value
is 0 for this parameter. This command requires explicit user
configuration for IPHC compression and decompression to
work.
