SDLC Adjacent Link When you configure SDLC adjacent link stations for APPN, if an active link Stations for APPN becomes inactive and you change the port definition using the PortDef parameter,
the link remains inactive. If you try to reactivate the link using the SET
Source Route The NETBuilder II bridge/router cannot interoperate with Cisco or IBM routers if Transparent Bridging the NETBuilder bridge/router is configured using Source Route Transparent
Gateway (SRTG) Gateway (SRTG) with Source Route bridging on the token ring LAN port and Interoperability Transparent Bridging on the PPP or Frame Relay WAN ports. In this configuration,
the NETBuilder II bridge/router is sending using PPP bridge encapsulation 802.5 token ring format, while the IBM 6611 and the Cisco 400 router are using PPP bridge encapsulation 802.3 Ethernet format.
