Updates using SNMP
By default, the Dell Networking system displays some unsolicited SNMP messages (traps) upon certain events
and conditions.
You can also configure the system to send the traps to a management station. Traps cannot be saved on the
system.
Dell Networking OS supports the following three sets of traps:
• RFC 1157-defined traps — coldStart, warmStart, linkDown, linkUp, authenticationFailure, and
egpNeighbborLoss.
• Dell Networking enterpriseSpecific environment traps — fan, supply, and temperature.
• Dell Networking enterpriseSpecific protocol traps — bgp, ecfm, stp, and xstp.
To configure the system to send SNMP notifications, use the following commands.
1 Configure the Dell Networking system to send notifications to an SNMP server.
