You notice that the secondary node of a chassis cluster has become disabled. What caused
An IPsec tunnel between the two devices failed.
The fxp0 interface on the secondary device failed.
The control link between the devices failed.
A reth on the secondary device failed.
One Comment on “What caused this behavior?”
If the control link has gone down but the Data link is still up there will be a heartbeat of sorts that tells the secondary firewall to become disabled. This is a controlled failure and the secondary firewall will go in to the disabled firewall.
