This article describes an issue in which the "Agent IP" or "agent-addr" field in SNPM v1 traps contain the empty IP address value "0.0.0.0".XOS 9.x versions prior to 9.5.6 and 9.6.2 populate the Agent IP or agent-addr field in SNMP v1 traps with an empty ("0.0.0.0") IP address. This causes issues with some software that processes SNMP traps.
Problem:
Certain software solutions (e.g. eHealth Trap Exploder) use the SNMP v1 "agent-addr" (also known as "Agent IP") field to determine the source of the trap. If the field is filled with 0.0.0.0, it causes problems for such software solutions.
Example:
Decoded SNPM v1 packet (UDP header and partial payload only):
This issue has been corrected in XOS V9.6.2 and XOS V9.5.6.
To resolve this issue, upgrade to XOS V9.6.2 or later, or to XOS V9.5.6 or later.
