Hi, we have two ASG 320 configured in Hot Standby mode.

I was wondering what the failover events are?

I mean when does the Master shut down and the Slave becomes the Master?

Is it enough if and Interface fails or does the whole Appliance has to fail?

Thanks.

The main cause for an Internet security system to fail is because of a hardware
failure.

All nodes monitor themselves by means of a heartbeat signal, a periodically
sent multicast UDP packet used to check if the other nodes are still
alive.

If any node fails to send this packet due to a technical error, the node
will be declared dead. Depending on the role the failed node had assumed, the
configuration of the setup changes as follows:

• If the master node fails, the slave will take its place and the worker node
with the highest ID will become slave.
• If the slave node fails, the worker node with the highest ID will become
slave.
• If a worker node fails, you may notice a performance decrease due to the
lost processing power. However, the failover capability is not impaired.

Allright,
so they only do a failover if the whole System fails. Or the Interface on which the Heartbeat is send.

Thanks.

Please Close.

how about configuration balancing, I have 2 link connection. what mush I do ?

Ghufron, that's a whole, separate issue unrealted to High-Availability.

Assuming that you mean you have two WAN connections, look in 'Network >> Interfaces' on the 'Uplink Balancing' and 'Multipath Rules' tabs.

yeah basically Either
(i)a system failure or
(ii)heartbeat signal interface failure or
(iii)both
