Cisco Catalyst Switch Manager Alarms
The following SNMP traps do not generate Cisco EMF alarms:
• bgpBackwardTransition
•
bgpEstablished
• cefcFanTrayStatusChange
•
cefcPowerStatusChange
• cefcUnrecognizedFRU
•
cHsrpStateChange
• chassisAlarmOff
•
chassisAlarmOn
• entConfigChange
•
ipPermitDeniedTrap
• lerAlarmOff
•
lerAlarmOn
• moduleDown
•
moduleUp
• sysConfigChangeTrap
•
tokenRingSoftErrExceededTrap
• vtpConfigDigestError
•
vtpConfigRevNumberError
• vtpVersionOneDeviceDetected
•
stpInconsistencyUpdate
• tcpConnectionClose
If these traps are received by the Cisco Catalyst Switch Manager software, they are ignored.
Several Cisco Catalyst Switch Manager alarms are generated based on the clogMessageGenerated
SNMP trap. This trap is generated by the CISCO-SYSLOG-MIB whenever a syslog message is recorded
into the message table. The severity of the Cisco EMF alarm is based on the clogHistSeverity varbind
value in the trap.
If a coldStart trap is received by the Cisco Catalyst Switch Manager software whose IP address
corresponds to the IP address of a Network Element object that is currently in the decommissioned state,
then that object is automatically commissioned. When the Network Element is commissioned, a
subchassis discovery is executed automatically. If the Network Element is populated with other Cisco
Catalyst Switch Manager objects, and if there is a mismatch between the type of Cisco Catalyst Switch
Manager object and the type that is discovered, the object is placed into the mismatched state and a
corresponding alarm is raised against that object (see the
“Object State Alarms” section on page 13-28 ).
The linkUp/linkDown SNMP traps signify that the operational status of a particular interface has
transitioned into or out of the down state. If a linkUp trap is received, it will clear any linkDown alarm
on the corresponding interface, if it exists.
If any other SNMP trap that is not listed in Table 13-2 is detected by the Cisco Catalyst Switch Manager
software, then a general informational alarm is raised against the Network Element object. The details
for this trap (enterprise and varbinds) is logged in the C6576MCntrllr.log file.
