Note: Commands for configuring SNMP on Enterasys devices are independent during the SNMP
setup process. For instance, target parameters can be specified when setting up optional
notification filters — even though these parameters have not yet been created with the set snmp
targetparams command. The steps in this section are a guideline to configuring SNMP and do not
necessarily need to be executed in this order.
