    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.

Hi Nitass, Quoted " If network failover traffic is compromised, the two units do not fail over because the hardwired failover cable still connects them " - can give an example of such scenario ? - do you mean the 2 units still show as active-standby status?
