## Symptoms

- SNMP monitoring server refuses to add cluster members running on Gaia OS due to duplicate SNMPv3 "engineID".

*Example* from Distributed SNMP Security Pack (DSSP) BRASS server:

* Trying to add a cluster member:

  ```
  
  /usr/local/Snmpri/DSSP/brass/bin # ./getmany -v3 IP_ADDRESS_OF_MEMBER passphrase system
  Request failed: duplicate engineID detected
  ```

* Checking for SNMPv3 "engineID" on cluster members showed that both cluster members report *identical* SNMPv3 "engineID":  

  ```
  
  /usr/local/Snmpri/DSSP/brass/bin/getsnmpid NETWORK_IP_ADDRESS/MASK | grep -v Timeout | grep -v 'ICMP Host Unreachable' | grep -v 'ICMP Port Unreachable' | grep -i 'SNMPv3_engineID'
  SNMPv3_engineID   IP_ADDRESS_OF_MEMBER_1
  SNMPv3_engineID   IP_ADDRESS_OF_MEMBER_2
  ```

## Cause

The involved cluster members running on Gaia OS are configured as members of the same Gaia "Cloning Group".

SNMPv3 "engineID" is generated automatically based on the machine's configuration. Because the involved cluster members are members of the same Gaia "Cloning Group", this SNMPv3 "engineID" was duplicated (cloned) as well.
