We have a cluster of two ASA5585-SSP60. One Master and one Slave. From NNM the boxes are polled with v3 on their individual interface address in context admin. The Master is OK with SNMPv3 and returns replies, but the Slave says "Authentication Failure". If we move the Master, the new Master answers correctly, but the new Slave doesn´t.
According o documentation the snmp v3 credentials should be entered on the slave, in addition to on the Master, but it is not allowed to do any config on a Slave.
"gwCore01/admin/gwA2core01(config)# snmp-server user nnm nnm v3 auth md$
Changing configuration is not allowed in slave unit."
Any idea how to make SNMP v3 to work on both Master and Slave(s).
