# sk183702 - False positive SNMP power supply traps on 9000 Appliances

| Property | Value |
|----------|-------|
| Solution ID | sk183702 |
| Date Created | 2025-08-04 |
| Last Modified | 2026-02-18 |
| Technical Level | General |
| Products | Security Gateway |
| Versions | R82, R81.20 |
| OS | Gaia |
| Platform | 9000 |

## 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`  
  `listening on Mgmt, link-type EN10MB (Ethernet), capture size 262144 bytes`  
  `09:19:42.704925 IP <1> > IP <2>: V2Trap(205) .1.3.6.1.2.1.1.3.0=57482657`  
  `.1.3.6.1.6.3.1.1.4.1.0=.1.3.6.1.4.1.2620.1.3000.5.4.1 .1.3.6.1.4.1.2620.1.3000.0.12.0=`  
  `"Power-Supply sensor 'Power Supply #2' reports 'Power-Supply down'"`  
  `.1.3.6.1.4.1.2620.1.6.7.9.1.1.2="Power Supply #2" .1.3.6.1.4.1.2620.1.6.7.9.1.1.2="Down"`

## 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.
