Secondary SDLC Limitations
Bay Networks routers configured as secondary SDLC link stations function as
PU 2.0 devices only.
Secondary SDLC Configuration
The DLSw Mode parameter allows you to configure primary or secondary
operations on DLSw interfaces and SDLC local devices. Refer to
Configuring
DLSw Services
for information on the DLSw Mode parameter.
Enhanced Synchronous Pass-through
Using primary and secondary SDLC services, a network can transport existing
SDLC traffic over a router-based topology that
• Enables existing SDLC traffic to use a high-speed multiprotocol backbone
network
• Simplifies the migration to a router-based network, by incorporating SDLC
traffic into the multiprotocol backbone without converting the existing
endstations
• Provides local acknowledgment of the SDLC protocol at each side of the
router-based network, eliminating polling and acknowledgment traffic from
the network backbone
• Allows high-speed links into the FEP, improving response time
Figure 1-3 illustrates locally acknowledged synchronous pass-through using
single and dual switch services.
