Continue on to Step 4

4. Select the protocol the WAN port will use.

CLI> define wan port protocolSupport

Note: PANL connections use the switching frame relay protocol (switchingFR) to direct traffic across the Passport network.




Parameter	Range of Values	Required Actions
<IfIndex>	INTEGER (1..255)	Enter the IfIndex of the physical WAN port as determined in Step 2.
<ProtocolSupport>	none | standardFr |switchingFR | htds | cbr | sdlc | x25 | async | pppHdlc | channel | hdlc | CasBypass	Enter swithchingFR. This protocol is always used when configuring netlinks on the Passport 4400.




Example:

CLI> define wan port ProtocolSupport 150 switchingFR

5. For Passport 4430/50/55, select the physical mode of the WAN port, DCE or DTE. The physical mode of the port determines if this port will generate clocking (dce) or accept clocking information (dte). For connections established across the frame relay network, the physical mode should usually be set to dte.

For the Passport 4460, select auto if you are using a Smart cable (go to Passport 4460). If you are not using a Smart cable, follow the instructions for Passport 4430/50/55.

Passport 4430/50/55

CLI> define wan port mode

Example:

CLI> define wan port mode 150 dte

Note: In the Passport 4430/50/55, if there is a supported interface module (such as an ISDN module) installed in Port 3 on the base module, Port 1 must be configured for DCE. In this case, the Passport 4400 will automatically assign DCE mode to Port 1 following a reset.

Passport 4460

When using a Smart cable with the Passport 4460, you do not need to execute the CLI command define wan port mode to set the DCE/DTE type. After you have configured other parameters on the factory defaulted Passport 4460 and reset the unit (after the save configuration update command), the correct type will be auto-sensed and set for this parameter.

If the above has not occurred, use the following CLI command to set the auto-sense parameter:

CLI> define wan port mode

Example:

CLI> define wan port mode 150 auto

6. Set the master clock source. If you do not want to perform this step, continue on to Step 7.

This feature is available on Passport 4460 units running software release 4.1.2 or higher. To determine if this feature is available on your Passport 4460 unit, use the CLI command show system hardware. A table similar to the following appears:

RevisionLevel	41
ManufactureRevDate	"2-9-00"
SerialNumber	PED0012478
ModuleID	2
MACAddress	00:e0:7b:0a:46:1a
CPUType	"Passport 4460/MPC860MH-MPC860T"
GenCfgType	passport 4460
ClockSync	supported




If Master Clock is supported on your Passport 4460, Supported will be displayed in the ClockSync field.

If your physical mode is set to dce and you want to use the Passport 4460 unit's master clock as the clock source, use the following CLI command:

CLI> define wan port ClockSource

Parameter	Range of Values	Required Actions
<IfIndex>	INTEGER (1..255)	Enter the IfIndex you entered in Step 1.
<ClockSource>	external | backplane	Enter backplane. External is the default.




Example:

CLI> define wan port ClockSource 1 backplane

7. If you are creating a netlink between two Passport units that are physically connected to each other using a cable (not connected through a public network), you must set the frame relay LMI mode for this connection. The same DLCI number must be configured on both sides of the link. Otherwise, the Passport 4400 units will not be able to communicate with each other.

If you are creating a netlink across a public frame relay network, go to step 8.

CLI> define fr line user basePVCLmi lmiMode

Parameter	Range of Values	Required Actions
<IfIndex>	INTEGER (1..255)	Look at the table in Step 1 and locate the IfIndex of the service (frameRelay) on the physical port being configured. This IfIndex will be the IfIndex of the physical port, plus 2. For instance, if you are configuring Port 2 on the base module (IfIndex 153), the IfIndex of the frame relay service will be 155.
<LMIMode>	unidce | unidte	Enter the frame relay LMI mode according to the logical PANL mode of the netlink. Enter unidte to specify it as "User" oriented on a Frame Relay User to Network Interface (FRUNI). The carrier's switch is always set to be the receiver of the frame relay PVC call setup, so it is set to unidce or "Network" oriented on the FRUNI.




Note: If you are configuring a connection between a Passport 4400 and a Passport 6400, the LMI Mode on the Passport 4400 should be set to unidte.




Example:

CLI> define fr line user basePVCLmi 155 unidce

Go to Step 9.

8. If you are creating a netlink across a public frame relay network, you must set the LMI type.

CLI> define fr line user dlcmiPVC lmiType

Parameter	Range of Values	Required Actions
<IfIndex>	INTEGER (1..255)	Look at the table in Step 1 and locate the IfIndex of the service (frameRelay) on the physical port being configured. This IfIndex will be the IfIndex of the physical port, plus 2. For instance, if you are configuring Port 2 on the base module (IfIndex 153), the IfIndex of the frame relay service will be 155.
<LMIType>	noLMIConfigured | itut933A | ansiT1617D1994	Enter the LMI type of the public frame relay network. The default setting is noLMIConfigured.




Example:

CLI> define fr line user dlcmiPVC LMIType 152 ansiT1617D1994

9. Assign an unused IfIndex number to the new netlink.

Note: To avoid conflict with additional modules and services that may be added to your Passport 4400 in the future, it is recommended that you select a number between 207 and 255.




Use the display from Step 1 (show system ifIndex configured) to verify that this new ifIndex number is not in use.
