Disable TCP/IP Header Compression
You can disable TCP/IP header compression by using either of two
commands that have different effects, depending on whether Fram
Relay IP maps have been explicitly configured for TCP/IP header
compression or have inherited their compression characteristics from
the interface.
Frame Relay IP maps that have explicitly configured TCP/IP heade
compression must also have TCP/IP header compression explicitly
disabled.
To disable TCP/IP header compression, perform one of these tasks in
interface configuration mode:
z
Disable TCP/IP header compression on all Frame Relay IP maps
that are not explicitly configured for TCP header compression.
no frame-relay ip tcp header-compression
frame-relay map ip
ip-address dlci
z
Disable TCP/IP header compression on a specified Frame Relay
IP map.
nocompress tcp header-compression
Example: Disabling Inherited TCP/IP Header Compression
In this first example, the initial configuration is:
interface serial 1
encapsulation frame-relay
ip address 131.108.177.179 255.255.255.0
frame-relay ip tcp header-compression passive
frame-relay map ip 131.108.177.177 177 broadcast
frame-relay map ip 131.108.177.178 178 broadcast tcp header-compression
Enter these commands:
serial interface 1
no frame-relay ip tcp header-compression
