Problem Solution
Unable to perform a
GET
• Verify the read (GET) community name (SNMPv1) or the user profile
configuration (SNMPv3).
• Use the command line interface or UI to ensure that the NMS has access.
See “SNMP screens”.
Unable to perform a
SET
•
•
Verify that SNMP is enabled. SNMPv1 and SNMPv3 are disabled by default.
Verify the read/write (SET) community name (SNMPv1) or the user profile
configuration (SNMPv3).
• Use the command line interface or UI to ensure that the NMS has write
(SET) access (SNMPv1) or is granted access to the target IP address
through the access control list (SNMPv3). See “SNMP screens”.
Unable to receive
traps at the NMS
• Make sure the trap type (SNMPv1 or SNMPv3) is correctly configured for
the NMS as a trap receiver.
• For SNMP v1, query the mconfigTrapReceiverTable MIB OID to verify that
the NMS IP address is listed correctly and that the community name defined
for the NMS matches the community name in the table. If either is not
correct, use SETs to the mconfigTrapReceiverTable OIDs, or use the
command line interface or UI to correct the trap receiver definition.
• For SNMPv3, check the user profile configuration for the NMS, and run a
trap test.
See “SNMP screens”, “Trap Receivers”, and “SNMP Traps test screen”.
Traps received at an
NMS are not
identified
See your NMS documentation to verify that the traps are properly integrated in
the alarm/trap database.
