Workgroup Remote Access Switch 409
P ROBLEM D IAGNOSIS
SNMP
Problem:
The CyberSWITCH does not generate SNMP Trap PDUs.
Action:
1.
Enter the snmp stats command at the administrative console. If an “SNMP is not enabled”
message appears, you must first enable the SNMP Agent (using CFGEDIT).
2. If the SNMP statistics are displayed, check the value of the “ snmpOutTraps ” statistic. If this
counter is zero, the SNMP agent has not generated any Traps. Check your configuration setup
and ensure that at least one SNMP Trap Receiver is configured. If the value of the
“
snmpOutTraps ” statistic is non-zero, the SNMP agent is generating Trap PDUs. If a given
Network Management Station is not receiving Traps as expected, check your configuration
setup and ensure that the IP address and the Community Name of the Network Management
Station that is not receiving Traps is configured properly.
3. Enter dr at the administrative console to display the current system messages. If one of the
following messages appears, the SNMP agent does not have enough memory to generate all of
the Trap PDUs that need to be generated. If the “snmpOutTraps” counter is not increasing
while these reports are being logged, there is an unexpected condition present within the
CyberSWITCH System software.

Problem:
The following message is continuously reported in the system log (enter the
dr console command
to display the system log):
[SNMP] Authentication failure, unknown community name
Action:
The Community Name specified in the request PDUs is not recognized by the SNMP Agent. To
correct this problem, use CFGEDIT to add the desired community name or change the
configuration of your Network Management Station so that it uses a Community Name that is
known to the CyberSWITCH.
Problem:
The following message is continuously reported in the system log (display the system log by
issuing the
dr console command):
[SNMP] Authentication failure, improper access rights
Action:
The Community Name specified in the request PDUs does not have the proper access rights to
perform the desired request. Use CFGEDIT to change the MIB access level of the indicated
Community Name to the desired access level or change the configuration of your Network
Management Station so that it uses a Community Name that has the desired MIB access level.
