Platform Troubleshooting
Diagnosing SNMP Failure
A variety of problems can cause the Cisco PGW 2200 Softswitch to fail to respond to SNMP requests.
The Cisco PGW 2200 Softswitch uses the Sun Microsystems Solaris 8 or Solaris 10 operating system.
Both Solaris 8 and Solaris 10 are 64-bit operating systems and older hardware platforms cannot support
them. SNMP failure can occur if the system hardware does not meet the requirements of the
Cisco PGW 2200 Softswitch software. The Cisco PGW 2200 Softswitch can have problems responding
to SNMP requests if you selected the 32-bit kernel instead of the 64-bit kernel when you installed the
Solaris 8 or Solaris 10 operating system. In such situations, the CIAgent application that processes
SNMP functions on the Cisco PGW 2200 Softswitch might fail and is unable to restart.
To diagnose the source of the SNMP failure, perform the following procedure:
Step 1 If you have not already collected system data, refer to the method that is described in the “Collecting
System Data for Cisco TAC” section on page 6-93.
Step 2 Determine whether the SNMP daemon (snmpdm) is running on your system by entering
the
ps -ef | grep snmp command.
The system should return a response like the following:
root 12061 1 0 Aug 27 ? 0:03 /opt/CiscoMGC/snmp/critagt -d
root 12072 12061 0 Aug 27 ? 0:00 /opt/CiscoMGC/snmp/brassagt -d
root 5233 5231 0 20:06:25 pts/2 0:00 grep snmp
root 12143 12061 0 Aug 27 ? 8:13 /opt/CiscoMGC/snmp/mib2agt -d
root 12144 12061 0 Aug 27 ? 5:54 /opt/CiscoMGC/snmp/hostagt -d
root 12145 12061 0 Aug 27 ? 0:00 /opt/CiscoMGC/snmp/fsagt -d
root 12068 12061 0 Aug 27 ? 13:38 /opt/CiscoMGC/snmp/snmpdm -tcplocal -d
If the response from your system does not include snmpdm, the SNMP daemon is not running.
If the SNMP daemon is not running, proceed to Step 3. Otherwise, proceed to Step 11.
Step 3 Verify that the hostname and IP address information for the Cisco PGW 2200 Softswitch system that is
configured on your SNMP server is correct.
If the hostname and IP address information are incorrect, proceed to Step 4. Otherwise, proceed to
Step 4.
Step 4 Modify the hostname and IP address information for the Cisco PGW 2200 Softswitch system on your
SNMP server.
If modifying the hostname and IP address resolves the problem, proceed to Step 10. Otherwise, proceed
to Step 5.
Step 5 Verify that the 64-bit kernel instruction sets are installed in your system by entering the isalist UNIX
command.
The system should return a response like the following:
sparcv9+vis sparcv9 sparcv8plus+vis sparcv8plus sparcv8 sparcv8-fsmuld sparcv7 sparc
If the response from your system does not include the sparcv9+vis and sparcv9 instruction sets, the
64-bit kernel is not installed on your system.
If the response indicates that the 64-bit kernel is installed in your system, proceed to Step 11. Otherwise,
proceed to Step 6.
