OS

Platform

Symptoms

SNMP power supply traps randomly report PSU Down for approximately 10 seconds before returning to Up status, while Gaia consistently shows power supply as Up.
No hardware issues or alerts appear in the Gaia Portal or in the "sysenv" history; power supply status remains green for extended periods.
No business impact occurs, but monitoring accuracy is compromised.
# snmpwalk -c <community> -v 2c localhost .1.3.6.1.4.1.2620.1.6.7.9.1.1.2 shows

"Power Supply Down", but # cpstat os -f power_supply shows "Power Supply Up".

tcpdump shows that snmp trap temporarily triggered over SNMP trap port 162:

# tcpdump -s0 -nni <interface_name> port 162

tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

Cause

Different system programs checking power supply status simultaneously caused false positive SNMP power supply trap reports, particularly affecting Quantum Force 9100 appliances with Jumbo Hotfix Accumulator R81.20.

Solution

This problem was fixed. The fix is included in:

Jumbo Hotfix Accumulator for R82 starting from Take 73
Jumbo Hotfix Accumulator for R81.20 starting from Take 122

If you choose not to upgrade, Check Point can supply a Hotfix. Contact Check Point Support to get a Hotfix for this issue.

A Support Engineer will make sure the Hotfix is compatible with your environment before providing the Hotfix.

For faster resolution and verification, please collect CPinfo files from the Security Management Server and Security Gateways involved in the case.

Hotfix installation instructions:

Refer to sk168597 - How to install a Hotfix.
