I know this topic has been discussed previously:
but, I have an additional question/concern regarding this setup. I also currently have the ASA pairs configured where only the active is configured with both IPS added. This is fine. The problem I have is a potential to miss syslog information regarding failover in the case of the standby ASA thinking it needs to become active and the Active not knowing about it. This has happened due to a topology problem and it would have been helpful to have logs from the Standby ASA archived. I know I can't add it through a discover because of the name discrepancy, but I can add it as a device so that it receives logs from the ASA. An additional problem with this is that, since I can't discover it, it can't recognize the names, etc... being sent through syslog (objects, etc). Has anyone successfully added an ASA in this situation? If not, I think this would be a helpful feature.
