Creating Cisco HDLC Interfaces

You can create an IP interface with its IP address on top of the Cisco HDLC interface.

NOTE: Cisco HDLC configuration is the same for all modules.

To create a Cisco HDLC interface:

1. Navigate to the appropriate level in the system's configuration to set Cisco HDLC encapsulation on an interface:

• For CT3, CT1, CE1, cOC3, or cOC12—Select a DS0 bundle.
• For T3-Frame, E3-Frame, X.21/V.35, or HSSI—Select a line interface.
• For OC48/STM16 POS, OC3/OC12 POS—Select a packet over SONET (POS) interface.

2. Right-click, select Create, and click Cisco HDLC.

The Create Cisco HDLC dialog box appears.

3. Set the parameters (Table 68).

 Table 68:  Cisco HDLC Parameters

4. When you have finished, click OK to save the settings.

Once you have created a Cisco HDLC interface, you can create an IP interface and an IP address on top of it. For more information about IP interfaces and addresses, see NMC-RX User Guide, Vol. 2, Chapter 6, Configuring IP.
