You can configure various features on the switch to generate SNMP traps that inform the NMS about events or problems that occur on the switch. Traps generated by the switch can also be viewed locally by using the Web-based interface or CLI. Why Is SNMP Needed? Some network administrators prefer to use SNMP as the switch management interface. Settings that you view and configure by using the Web-based Dell OpenManage Switch Administrator and the CLI are also available by using SNMP. If you do not use NMS software to manage or monitor other devices on your network, it might not be necessary to configure SNMP on the switch. Default SNMP Values By default, SNMPv2 is automatically enabled on the device. SNMPv1 and SNMPv3 are disabled. To enable SNMPv3, you must define a local engine ID for the device. The local engineID is by default set to the switch MAC address, however when the switch operates in a stacking mode, it is important to manually configure the local engineID for the stack. This local engineID must be defined so that it is unique within the network. It is important to do this because the default engineID in a stack is the MAC address of the master unit, which may change if the master unit fails and another unit takes over the stack. Table 12-1 summarizes the default values for SNMP. Table 12-1.
