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.
