- Define X.25 services to the virtual port pairs. You must configure one end (the slave unit) as DTE. If the remote end is a FRAD, the FRAD is usually a DTE. In this case, the Passport 4400 unit should be set for DCE and should be the master end.
CLI> define x25 parameters interfaceMode
| Parameter | Range of Values | Required Action |
| <Index> | Integer (1..255) | Enter the IfIndex of the virtual port. |
| <InterfaceMode | dte | dce | DCE is the default. Select DTE at the slave end. Make sure that one end of the X.25 connection is DCE and the other end is DTE. |
Example:
CLI> define x25 parameters interfaceMode 51 dte
There are many other X.25 parameters that you should review and set as required for your network. See Defining X.25 Parameters for more information.
- Add X.25 routing information.
Refer to Configuring X.25 SVCs for information about the X.25 routing table.
CLI> add x25 routing
| Parameter | Range of Values | Required Action |
| <Index> | Integer (1..255) | Enter a number for this route. |
| <DestinationIfIndex> | Integer (1..255) | Enter the IfIndex of the local X.25 virtual port (the packet layer IfIndex). |
| <DnaPattern> | Quoted string (1..15) | Enter the X.25 DNA address to be assigned to the local virtual port. The address must be entered as a quoted string. An asterisk (*) can be used as part of the DNA address pattern. |
Example:
CLI> add x25 routing 2 51 "1234543210"
- Save the configuration:
CLI> save configuration update
- Make sure you have the required type of virtual circuit established for communications across the WAN:
- If your network requires X.25 PVCs, you should configure them at this time.
See Configuring X.25 PVCs for information and procedures for establishing X.25 PVCs.
- Reset the unit:
CLI> reset system current reset
