15 Simple Network Management Protocol (SNMP) Network management stations use SNMP to retrieve or alter management data from network elements. A datum of management information is called a managed object; the value of a managed object can be static or variable. Network elements store managed objects in a database called a management information base (MIB). MIBs are hierarchically structured and use object identifiers to address managed objects, but managed objects also have a textual name called an object descriptor. NOTE: An I/O Aggregator supports standard and private SNMP MIBs, including Get operations in supported MIBs. Implementation Information The Dell Networking OS supports SNMP version 1 as defined by RFC 1155, 1157, and 1212, SNMP version 2c as defined by RFC 1901. Configuring the Simple Network Management Protocol NOTE: The configurations in this chapter use a UNIX environment with net-snmp version 5.4. This is only one of many RFC-compliant SNMP utilities you can use to manage the Aggregator using SNMP. Also, these configurations use SNMP version 2c. Configuring SNMP version 1 or version 2 requires only a single step: 1. Create a community. NOTE: IOA supports only Read-only mode. Important Points to Remember • Typically, 5-second timeout and 3-second retry values on an SNMP server are sufficient for both local area network (LAN) and wide area network (WAN) applications. If you experience a timeout with these values, increase the timeout value to greater than 3 seconds, and increase the retry value to greater than 2 seconds on your SNMP server. 178 Simple Network Management Protocol (SNMP)
