Disable TCP/IP Header Compression

Chapter 13: AI2524 Frame Relay Configuration Steps

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:

zDisable 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

zDisable 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
