Simple Network Management Protocol, or SNMP, is an application-layer protocol for configuring and monitoring switches and other devices on the network. Each switch uses a database called a management information base (MIB). The MIB contains hundreds of data points called object identifiers, or OIDs. Some of the OIDs are read-only, such as the System Identifier, while others are read/write by the network administrator. The switch modifies some OIDs, for example, a temperature OID. Network administrators modify other OIDs, such as a port channel.

Each switch uses a different set of MIBs that are customized for that switch. Dell Technologies updates MIB files when the associated firmware files are updated. For this reason, MIBs are available from the same download page on the Dell Technologies Support page or are in the zipped firmware package.

OpenManage Network Manager (OMNM) is a one-to-many management tool based primarily on SNMP. OMNM allows network administrators to work with many switches on the network at one time. CLI and web UI interfaces only allow you to manage one switch at a time. Use OMNM to configure, manage, monitor, inventory, backup, and restore several Dell EMC switches at once.
