example, if the DTE with CUG number as 10 wants to call the DTE with CUG number as 20 in the network, the device will first find the map in the map table. If the map is found, change the CUG number of the calling packet to 20 and forward the packet; if not found, refuse to forward the packet.

You can specify the suppress rule while configuring CUG map. There are three suppress rules:

1Suppress income access no-incoming

2Suppress outgoing access no-outgoing

3Specify the preference rule preferential

Among them, preference rule is specified as related with suppress CUG policy, that is, if suppress policy is set to suppress CUG in the preferential mapping call (the suppress preferential parameter), then delete the CUG facility in the incoming packets of the map and process the calls.

Related command: x25 call-facility,x25 cug-service.

n If the command is used at DCE side, use the link-protocol x25 dce command to set the interface as DCE.

Example # Define the rule on the serial interface Serial2/0: the incoming calls with 100 local CUGs or 200 network CUGs are denied.

x25 map

Syntax x25 map protocol-type protocol-address x121-addressx.121-address [ option ]

undo x25 map { ip compressedtcp } protocol-address

View Interface view

Parameter protocol-type: Protocol type, with ip (IP protocol) and/or compressedtcp (IP protocol supporting TCP header compression). If you want to configure both of them, ensure that the protocol-addressare same for both ip and compressedtcp. The compressedtcp requires correct configuration for all the link ends, otherwise, the link may be blocked.

protocol-address: Network protocol address of the peer host.

x121-addressx.121-address: X.121 address of the peer host.

option: Specifies some attributes or user facilities for the address mapping.

The following gives the detailed information of options:
