1 Fabric Watch components TABLE 8 Security class areas (Continued) Area Indicates SLAP Bad Packets SLAP Failures Telnet Violation TS Out of Sync WSNMP Violation A SLAP (Switch Link Authentication Protocol) bad packets failure occurs when the switch receives a bad SLAP packet. Bad SLAP packets include unexpected packets and packets with incorrect transmission IDs. A SLAP failure occurs when packets try to pass from a nonsecure switch to a secure fabric. A telnet violation occurs when a telnet connection request reaches a secure switch from an unauthorized IP address. A TS (Time Server) out-of-synchronization error has been detected. A WSNMP violation occurs when an SNMP set operation reaches a secure switch from an unauthorized IP address. SFP class areas Table 9 lists Product Name areas in the SFP class and describes each area. NOTE SFPs connected to GbE ports are not monitored. TABLE 9 SFP class areas Area Description Temperature Receive Power Transmit Power Current Supply Voltage The temperature area measures the physical temperature of the SFP, in degrees Celsius. A high temperature indicates that the SFP might be in danger of damage. The receive power area measures the amount of incoming laser, in µwatts, to help determine if the SFP is in good working condition. If the counter often exceeds the threshold, the SFP is deteriorating. The transmit power area measures the amount of outgoing laser, in µwatts. Use this to determine the condition of the SFP. If the counter often exceeds the threshold, the SFP is deteriorating. The current area measures the amount of supplied current to the SFP transceiver. Current area events indicate hardware failures. The supply voltage area measures the amount of voltage supplied to the SFP. If this value exceeds the threshold, the SFP is deteriorating. ELEMENTS Product Name defines an element as any fabric or switch component that the software monitors. Within each area, the number of elements is equivalent to the number of components being monitored. For instance, on a 64-port switch, each area of the Port class includes 64 elements. Each element contains information pertaining to the description suggested by the area. To continue the Ports example, each element in the Invalid word area of Ports would contain exactly 64 ports, each of which would contain the number of times invalid words had been received by the port over the last time interval. Each of these elements maps to an index number, so that all elements can be identified in terms of class, area, and index number. As an example, the monitoring of the temperature sensor with an index of 1 can be viewed by accessing the first temperature sensor within the temperature area of the environment class. 10 Fabric Watch Administrator's Guide 53-0000438-01
