Configuring DLSw Services
2-12
• DLSw or SRB, whichever receives a response first, takes precedence. The
slower subsystem ceases any further attempts to support a connection to the
target program.
Figure 2-9. DLSw and Source Route Bridging on SRB Circuits
DLSw on an Ethernet/802.3 Circuit
The router supports DLSw configured on an Ethernet/802.3 circuit. The DLSw
software provides bridging services between Ethernet/802.3 LAN segments
locally attached to the same router.
The DLSw interface takes precedence over the transparent bridge interface
whenever the destination SAP address identified in a TEST frame received from
the local circuit already exists in the router’s DLSw configuration. In this case,
only the DLSw interface
• Captures the locally received TEST frame
• Attempts to locate the destination SAP address specified in that frame
