6 SNMP issues • If you think this is a policy-related issue, FCS switch or other security server-related issue then use supportSave -n to collect data from the Primary FCS switch and all affected switches. • If login-related, then also include the following information: - Does login problem appear on a Serial, CP IP, or Switch IP address connection? - Is it CP0 or CP1? - Is the CP in active or standby? - Is it the first time login after firmwareDownload and reboot? SNMP issues Symptom This section describes symptoms with associated causes and recommended actions for SNMP-related issues. SNMP management station server is unable to receive traps from fabric. Probable cause and recommended action There are several causes related to this generic issue. You will need to verify the following: • There are no port filters in the firewalls between the fabric and the SNMP management station. • If your SNMP management station is a dual-homed server, check that the routing tables are set up correctly for your network. If you continue to have problems, collect the data in the next section and contact your switch support provider. Gathering additional information In addition to supportSave, gather the MIB browser snapshot with the problem (like Adventnet screen snapshot) for an MIB variable. FIPS issues Symptom This section describes symptoms with associated causes and recommended actions for problems related to FIPS. When FIPS is turned on the switch constantly reboots. Probable cause and recommended action When FIPS is turned on the switch runs conditional tests each time it is rebooted. These tests run random number generators and are executed to verify the randomness of the random number generator. The conditional tests are executed each time prior to using the random number provided by the random number generator. The results of all self-tests, for both power-up and conditional, are recorded in the system log or are output to the local console. This includes logging both passing and failing results. If the tests fail on your switch it will constantly reboot. Because boot PROM access is disabled you will not be able to exit out of the reboot. You will need to send the switch back to your switch service provider for repair. 66 Fabric OS Troubleshooting and Diagnostics Guide 53-1001769-01

SNMP issues
6
If you think this is a policy-related issue, FCS switch or other security server-related issue then
use
supportSave -n
to collect data from the Primary FCS switch and all affected switches.
If login-related, then also include the following information:
-
Does login problem appear on a Serial, CP IP, or Switch IP address connection?
-
Is it CP0 or CP1?
-
Is the CP in active or standby?
-
Is it the first time login after
firmwareDownload
and reboot?
SNMP issues
This section describes symptoms with associated causes and recommended actions for
SNMP-related issues.
Symptom
SNMP management station server is unable to receive traps from fabric.
Probable cause and recommended action
There are several causes related to this generic issue. You will need to verify the following:
There are no port filters in the firewalls between the fabric and the SNMP management station.
If your SNMP management station is a dual-homed server, check that the routing tables are
set up correctly for your network.
If you continue to have problems, collect the data in the next section and contact your switch
support provider.
Gathering additional information
In addition to
supportSave
, gather the MIB browser snapshot with the problem (like Adventnet
screen snapshot) for an MIB variable.
FIPS issues
This section describes symptoms with associated causes and recommended actions for problems
related to FIPS.
Symptom
When FIPS is turned on the switch constantly reboots.
Probable cause and recommended action
When FIPS is turned on the switch runs conditional tests each time it is rebooted. These tests run
random number generators and are executed to verify the randomness of the random number
generator. The conditional tests are executed each time prior to using the random number provided
by the random number generator.
The results of all self-tests, for both power-up and conditional, are recorded in the system log or are
output to the local console. This includes logging both passing and failing results. If the tests fail on
your switch it will constantly reboot. Because boot PROM access is disabled you will not be able to
exit out of the reboot. You will need to send the switch back to your switch service provider for
repair.
