Subscribe to Managed Object Value Updates using SNMP

By default, the Dell Force10 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.
FTOS supports the following three sets of traps:
• RFC 1157-defined traps: coldStart, warmStart, linkDown, linkUp, authenticationFailure,
egpNeighbborLoss
• Dell Force10 enterpriseSpecific environment traps: fan, supply, temperature
• Dell Force10 enterpriseSpecific protocol traps: bgp, ecfm, stp, vrrp, xstp,
To configure the system to send SNMP notifications:
Step Task

RFC-defined traps using the command
