Modular Ethernet Switch User's Guide ♦ Link Change Event This trap is sent whenever the link of a port changes from link up to link down or from link down to link up. ♦ Port Partition This trap is sent whenever a port is partitioned as a result of more than sixty-one collisions on the port (i.e., is automatically partitioned). The number of collisions that triggers this trap is the same at either 10Mbps or 100Mbps. ♦ Broadcast Storm This trap is sent whenever the port reaches the broadcast storm rising or falling threshold. ♦ Power Supply Module Inserted This trap is sent whenever a redundant power supply module is installed in the switch. ♦ Power Supply Module Removed This trap is sent whenever a redundant power supply module is removed in the switch. ♦ Bad Power This trap is sent whenever a redundant power supply is receiving AC power but not supplying DC power to the switch. ♦ Power Supply Module Inserted This trap is sent whenever a redundant power supply is installed in the switch. ♦ Power Supply Module Temperature Warning This trap is sent whenever the temperature of a redundant power supply module measures over 80° C (176° F). ♦ Power Supply Module Voltage Warning This trap is sent whenever a redundant power supply generates DC current over 3.9 volts. ♦ Power Supply Module Current Warning This trap is sent whenever a redundant power supply generates DC current over 60 amps. ♦ System Fan Failure This trap is sent whenever one of the four system fans in the switch fails. ♦ Power Fan1 Failure This trap is sent whenever one of the two fans on a redundant power supply module fails. ♦ Power Fan2 Failure This trap is sent whenever one of the two fans on a redundant power supply module fails. MIBs Management information and counters are stored in the Switch in the Management Information Base (MIB). The Switch uses the standard MIB-II Management Information Base module. Consequently, values for MIB objects can be retrieved from any SNMP-based network manager software. In addition to the standard MIBII, the Switch also supports its own proprietary enterprise MIB as an extended Management Information Base. These MIBs may also be retrieved by specifying the MIB's Object-Identity (OID) at the network manager. MIB values can be either read-only or read-write. Read-only MIBs variables can be either constants that are programmed into the Switch, or variables that change while the Switch is in operation. Examples of read-only constants are the number of ports and types of ports. Examples of read-only variables are the statistics counters such as the number of errors that have occurred, or how many kilobytes of data have been received and forwarded through a port. Read-write MIBs are variables usually related to user-customized configurations. Examples of these are the Switch's IP Address, Spanning Tree Algorithm parameters, and port status. If you use a third-party vendors' SNMP software to manage the Switch, a diskette listing the Switch's propriety enterprise MIBs can be obtained by request. If your software provides functions to browse or modify MIBs, you can also get the MIB values and change them (if the MIBs' attributes permit the write operation). This process however can be quite involved, since you must know the MIB OIDs and retrieve them one by one. Switch Management Concepts 21
