The SDLC is a link layer protocol relative to the SNA. Its working principle is similar
to that of HDLC. In order to make DLSw work normally, you need to configure an
SDLC interface by specifying SDLC as the link layer protocol on the synchronous
serial interface.
Follow these steps to configure an SDLC interface:
To do...
Enter system view
Enter interface view
Configure SDLC
encapsulation on the
interface
Note that the SDLC link layer protocol cannot underlie the IP protocol, so all the
IP-related configurations on the interface must be removed before you configure
SDLC encapsulation. For example, you need to delete the IP address of the
interface.
With DLSw forwarding enabled on the SDLC interface, all local SNA devices
connected to the interface will be able to communicate with the remote device
through DLSw.
Follow these steps to enable DLSw forwarding on an SDLC interface:
To do...
Enter system view
Enter interface view
Enable DLSw forwarding on
the interface
In contrast with HDLC, SDLC is an "unbalanced" link layer protocol. That is, the
end systems across a TCP connection are not equal in the positions: one is primary
and the other is secondary. The primary station, whose role is primary, plays a
