I was required to check (as this customer did not have a trap collector) which node was active for redundancy group 0 on a SRX cluster. So I thought I would check for a SNMP OID that is only presented by the active RG0 node. This script uses snmpwalk and is configured to use SNMP v2c [ View Post… ]
