Command Reference
x25 map
Purpose Use the x25 map command to set the address mapping between IP address used by
LANs and X.121 address.
Use the undo x25 map command to delete one existing mapping.
Syntax x25 map { ip | compressedtcp } protocol-address x121-address
x.121-address [ option ]
undo x25 map { ip | compressedtcp } protocol-address
Parameters ip
Uses IP protocol.
compressedtcp
Uses TCP header compression.
protocol-address
Network protocol address of the peer host.
x.121-address
X.121 address of the peer host.
option
Specifies some attributes or user facilities for the
address mapping.
Default By default, no address mapping is set.
Example Set two address mappings on the X.25 interfaces Serial0/0/0 and Serial1/0/0,
respectively, and the four address mappings have different attributes.
[3Com] interface serial 0/0/0
[3Com-Serial0/0/0] x25 map ip 202.38.160.11 x121-address 20112451

Description Since X.25 protocol can multiplex more logical virtual circuits on a physical interface,
you need to manually specify the mapping relation between all network addresses
and X.121 address.
Once you have specified an address mapping, its contents (including protocol
address, X.121 address and all options) cannot be changed. To make modifications,
you can first delete this address mapping via the
undo x25 map command, and
then establish one new address mapping.
