Use the show frame-relay map command to display the resulting compression and encapsulation characteristics:

Router> show frame-relay map

Serial 1 (administratively down): ip 131.108.177.177 177 dlci 177(0xB1, 0x2C10), static,

broadcast

CISCO

Serial 1 (administratively down): ip 131.108.177.178 178 dlci 178(0xB2,0x2C20), static

broadcast

CISCO

TCP/IP Header Compression (enabled)

As a result, header compression is disabled for the first map (with DLCI 177), which inherited its header compression characteristics from the interface. However, header compression is not disabled for the second map (DLCI 178), which is explicitly configured for header compression.

Example: Disabling Explicit TCP/IP Header Compression

In this second example, the initial configuration is the same as the pre- vious example, but you enter these commands:

serial interface 1

no frame-relay ip tcp header-compression frame-relay map ip 131.108.177.178 178 nocompress

Use the show frame-relay map command display the resulting compression and encapsulation characteristics:

Router> show frame-relay map

Serial 1 (administratively down): ip 131.108.177.177 177 dlci 177(0xB1,0x2C10), static,

broadcast

CISCO

Serial 1 (administratively down): ip 131.108.177.178 178 dlci 178(0xB2,0x2C20), static

broadcast ISCO

The result of the commands is to disable header compression for th first map (with DLCI 177), which inherited its header compression characteristics from the interface, and also explicitly to disable header compression for the second map (with DLCI 178), which was explic- itly configured for header compression.
