LLC2 Protocol

The Class II logical link control driver (LLC2) interfaces network software (NetBIOS, SNA, OSI) running under the Solaris operating environment to a physical LAN network controlled by one of the supported communications adapters. The LLC2 driver, which appears as a driver to the network software, resides in the kernel and is accessed by standard UNIX STREAMS functions.

This version of the LLC2 driver includes support for both connectionless and connection-oriented logical link control class II LLC2 operations for Ethernet, Token Ring, and FDDI adapters when accessed through the appropriate Solaris MAC layer driver. The Data Link Provider Interface (DLPI) to the LLC2 driver enables multiple and different protocol stacks, (including NetBIOS and SNA), to operate simultaneously over one or more local area networks.

For more information on LLC2, see the System Administration Guide, Volume 3. For more information on DLPI, see the STREAMS Programming Guide and the man page dlpi(7P).

This feature was first available in the Solaris 7 8/99 release.
