OpManager accesses the remote devices using the protocols SNMP, CLI, or WMI. The credentials like the password/snmp community, port etc., may differ for different device types. Pre-configuring a set of credentials in OpManager helps applying them to multiple devices at a time, saving a lot of manual effort.
