SNA Over SDLC

The following configuration procedure assumes that the port chosen for SNA over SDLC operation has already been configured for mode (DCE/DTE), baud, encode method, frame relay, and tunnel parameters (netlink).

1. Set the port for SDLC operation.

Select Configure and Physical Interfaces from the navigation menu:



Select the type of port (serial, ISDN, CSU) you want to configure for SNA SDLC operation. Then, select the physical port (example screens shown are from Passport 4460 units):



You will see the Physical Port Configuration screen. The parameters that need your attention at this point are:

• Mode: select either DCE or DTE, depending on the type of SNA SDLC device that is attached to this port.
• Baud Rate: select the required baud rate for the physical port. The default is 64,000 bits per second. SNA connections have been tested at 9600, 19,200, 56,000, and 64,000 bits per second.
• Protocol Supported: select SDLC from the pull down menu, as follows:

Click on the Save button. "Command Successful" should be displayed when the unit finishes setting the configuration.

Continue on to step 2.
