Configuring an SDLC address for a secondary station

The SDLC protocol allows multiple virtual circuits to run on an SDLC physical link, with one end connected to the primary station and the other end to a secondary station. To distinguish different virtual circuits, specify an SDLC address for each virtual circuit. SDLC is an "unbalanced" protocol, a primary station can be connected with multiple secondary devices through a multiuser system or an SDLC switch, and the secondary devices cannot be connected with one another. The communication between the primary station and each secondary station can be guaranteed as long as each secondary device is identified with an SDLC address.

The following commands are used to specify an SDLC address for a virtual circuit, which is unique on a physical interface. The configured SDLC address on a synchronous serial interface is actually the address of the secondary SDLC station. On the serial interface of the DLSw router connected with the primary SDLC station, configure the address of each secondary SDLC station that communicates with the primary station. On the serial interface of the DLSw router connected with a secondary SDLC station, configure the address of each secondary SDLC station connected with the serial interface.

An SDLC address is in the range of 0x01 to 0xFE. The SDLC address of a router is valid on only one physical interface. The SDLC addresses configured on different interfaces can be identical.
