May 25, 2015network failover/serial cable for HA
for HA configurations, there are 3 options
- network failover
in network failover the heartbeat is the network packet
- serial failover
serial cable failover is just checking a voltage heartbeat between the two systems.
- network and Serial failover
I not sure does it mean failover only take place when network and serial both are failed or ? if use both, how to test if it is working?
network and Serial failover
If you configure a BIG-IP high-availability pair to use network failover, and the hardwired failover cable also connects the two units, hardwired failover always has precedence; if network failover traffic is compromised, the two units do not fail over because the hardwired failover cable still connects them.
