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:
Table 48-1 lists the traps the RFC-defined SNMP traps and the command used to enable each. Note that
the coldStart and warmStart traps are enabled using a single command.
To enable a subset of Dell Force10 enterprise-specific SNMP traps, enter any of the
snmp-server enable
traps
command options in Table 48-2. Note that the envmon option enables all environment traps,
including
fan, supply, and temperature.
