Note In the OSI internetworking model the physical layer manages the transmission of bits across the physical media for example cable or modem interface the physical layer protocol defines the electrical and mechanical interface The data link layer defines the procedures for transferring data accurately and reliably across the physical layer This guide assumes that the router s configuration file includes Ethernet FDDI or token ring network circuits See Configuring and Managing Routers with Site Manager for information on adding circuits 117344 A Rev A Configuring Ethernet FDDI and Token Ring Services Accessing Line Services When you add an Ethernet FDDI or token ring circuit the router software automatically sets default values for line services Using the BCC Using the show config command you can view the current configuration of a Bay Networks router including the location of configured line services Note This guide assumes that you are working with a router configuration file that already contains the appropriate WAN circuits for the hardware configuration See Configuring and Managing Routers with Site Manager for information about adding circuits to a configuration file Using the BCC issue the show config command to locate configured line services as follows box show config box type frecn board slot 13 type genf back console portnum 1 prompt slot auto manager script
