To secure the device , management traffic to and from the GUI Device Manager can be encrypted with SSL and Simple Network Management Protocol Version 3 ( SNMPv3 ) . You can view and graph more than 60 Cisco MDS 9000 Family statistics , including byte and frame counts by class , specific error counts , and all other protocol statistics ( Figure 3 ) . Simple Network Management Protocol Version 3 ( SNMPv3 ) ( non-cryptographic ) monitors and controls network devices as well as manages configurations , performance , collection of statistics , and security . Additional capabilities such as real-time performance monitoring and analysis of Fibre Channel operations at the frame level are needed to find root causes for the most challenging problems . Simplifying the complexity of managing the server farm is inherently built in through the use of VLAN 's . Statistics on Fibre Channel control traffic and distribution of frame sizes also provide valuable clues for resolving performance issues . A hash is created in hardware from the source and destination FCID within the frame that serves as an index as to what physical link in the virtual link this traffic should take . If you did n't have a chance to read the Drucker essay we mentioned yesterday , take 15 minutes to digest it . It was often quite comical to watch novice CEOs play " blame and sue " with the layer of companies who were a step closer to the customer in the supply chain . The Cisco MDS 9000 Family multilevel performance analysis solution also allows you to analyze Fibre Channel traffic at the frame level in real time or from capture files through a GUI .
