This describes the dip and jumper settings physically set on the efdmim board. Switch multiply 2**n Root 0 Forward Broadcasts 1 Spanning Tree 2 BPDU Type 3 Bypass 4 Ring Select 5 Diagnostics 6 Mode 7 Root: If 0, then spanning tree root is selected. If 1, then spanning tree root is NOT selected. Forward Broadcasts: If 0, then all broadcast packets are forwarded. If 1, then all broadcasts packets are filtered. Spanning Tree: If 0, then spanning tree facilities are enabled. If 1, then spanning tree facilities are disabled. BPDU Type: If 0, then spanning tree uses the IEE bridge packet protocol. If 1, then spanning tree uses the DEC bridge packet protocol. Bypass: If 0, then there is an optical bypass physically attached to the bridge. If 1, then there is not an optical bypass attached to the bridge. Ring Select: If 0, the bridge should attach to the primary FDDI ring (Through-A mode). If 1, the bridge should attach to the secondary FDDI ring (Through-B mode). Diagnostics: If 0, the bridge is in it's normal mode of operation. If 1, then the bridge is running self diagnostics. Mode: If 0, the bridge is an encapsulating bridge (talks from ethernet to ethernet using FDDI only as a backbone). If 1, the bridge is a translation bridge ( talks ethernet to ethernet, and ethernet to FDDI).
