FDDI networks employ two types of frames: (1) the token, which is a special frame that enables a node to access the ring and (2) the frame itself. FDDI token and frame formats are quite different from a token ring frame format Instead of bit definitions, FDDI networks use "symbols," ...
If an SMT agent (such as the SunNet Manager proxy agent delivered with SunFDDI/P) receives an unsupported or unrecognized request, it issues an RDF frame to indicate that the request is rejected. An RDF frame is always a response. Chapter 4 Using the SunFDDI Network Utilities 33 ESF (...
Shut off the computer and reinstall the adapter. If the problem persists, refer to Chapter 4 for troubleshooting information. Other LEDs remain off until the software driver is installed. The installation of the hardware for the 5611 S/FDDI Adapter is complete. Next, install the network software...
Methods This strategy used to discuss the design and implementation technology of network adapter, bridge, concentrator, device driver, Netware interface software, and a complete set of FDDI optical fiber computer network. All source address tracking, frame forwarding, frame format conversion, spanning ...
A lost frame is defined as an SMT frame whose reception is Chapter 2 Using the SunFDDI Network Utilities 15 aborted by the local station. It does not indicate the location of the cause of the error. A large number of lost frames can indicate a noise problem on the network, either dirt...
Chapter 2 Using the SunFDDI Network Utilities 19 ESF (Extended Service Frame) These frames are implementation dependent. An ESF frame can be an announcement, a request, or a response. PMF (Parameter Management Frame) These frames are used to access remote station attributes. The Parameter ...
