sdlc controller
Use sdlc controller to configure the address of a secondary SDLC station address.
Use undo sdlc controller to delete the address of a secondary SDLC station.
Syntax
sdlc controller sdlc-address
undo sdlc controller sdlc-address
Default
No secondary SDLC station address is configured.
Views
Synchronous serial interface view
Default command level
2: System level
Parameters
sdlc-address: Address of the secondary SDLC station to be configured, in the range of 0x01 to 0xFE.
Usage guidelines
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 connected to the secondary station. In order to distinguish
different virtual circuits, you must 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 multi-user 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. This command
specifies 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 a secondary
SDLC station.
• On the serial interface of the DLSw router connected with the primary SDLC station, you must
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, you must
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. As a result, the SDLC addresses configured on different interfaces can be the same.
Examples
# Set the secondary SDLC station address to 0x05 on Serial 2/0.
<Sysname> system-view
[Sysname] interface serial 2/0
[Sysname-Serial2/0] sdlc controller 05
sdlc enable dlsw
Use sdlc enable dlsw to enable DLSw forwarding on the current synchronous serial interface.
Use undo sdlc enable dlsw to disable DLSw forwarding on the current synchronous serial interface.
