Secondary SDLC Support
A Bay Networks router acting as a secondary device on an SDLC link can
• Support a single SDLC link communicating to a front end processor (FEP) or
similar SNA device
• Serve as a secondary PU 2.0 device on that link
• Coexist with other secondary SDLC devices, (PU 2.0 or PU 2.1) on the same
SDLC link
• Allow SNA devices attached to multiple remote routers to share a single
SDLC link to the FEP
• Attach to the FEP directly (using a null modem cable) or via a leased line
Figure 1-2 illustrates DLSw single and dual switch networks where Bay
Networks routers serve as secondary SDLC nodes.
