Enabling SDLC encapsulation on an interface
The SDLC is a link layer protocol relative to the SNA. Its working principle is similar to HDLC. For DLSw to work correctly, enable SDLC encapsulation on the synchronous serial interface.
To enable SDLC encapsulation on an interface:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter interface view. | interface interface-type interface-number | N/A |
3. Enable SDLC encapsulation on the interface. | link-protocol sdlc | PPP encapsulation by default. |
The SDLC link layer protocol cannot underlie the IP protocol, so all the IP-related configurations on the interface must be removed before you enable SDLC encapsulation on the interface. For example, you must delete the IP address of the interface.
