Hi nitass,
I was able to get it working with the link you provided, however there is still some issues:
1) I could not add two servers for destination syntax
tmos> modify sys db config.auditing.forward.destination value 192.168.1.45 192.168.1.46 (not working) unless only one server. I tried different parameters "{" still did not take it.
2) tmos> save /sys config did not save to the standby unit. Even after b config sync all, the config did not appear in standby unit. (running v10.2.x)
tmos> show running-config sys db config.auditing.forward.destination {
sys db config-auditing.forward.destination
value "192.168.1.45"
}
3) Getting Peer communication which is the standby heartbeat address on the Tacacs+ server. I don't want this audit
tmos> modify sys db config.auditing.forward.destination value 192.168.1.45 192.168.1.46
tmos> modify sys db config.auditing.forward.shared value "mysecret"
tmos> modify sys db config.auditing.forward.type value tacacs+
tmos> modify sys db config.auditing value enable
tmos> modify sys db log.mcpd.level value info
tmos> save /sys config
