If so how does the failover occur? Is it based on interface monittoring?</P><P>If not, how does instances failover work? If Instance A on FP1 is down does only Instance A on FP2 take over or does the entire chassis Failover?&nbsp;</P> Fri, 21 Feb 2020 17:10:15 GMT https://community.cisco.com/t5/network-security/multi-instance-failover/m-p/3862800#M942685 dvalinho 2020-02-21T17:10:15Z https://community.cisco.com/t5/network-security/multi-instance-failover/m-p/3864226#M942686 <P>Failover in multi-instance works the same way as in native mode, i.e. by monitoring the unit and interface health.</P> <P>Failover in 1 HA pair does not impact the failover state in another HA pair.</P> Wed, 29 May 2019 05:49:38 GMT https://community.cisco.com/t5/network-security/multi-instance-failover/m-p/3864226#M942686 Ilkin 2019-05-29T05:49:38Z https://community.cisco.com/t5/network-security/multi-instance-failover/m-p/3950382#M942687 Thanks Wed, 30 Oct 2019 11:24:21 GMT https://community.cisco.com/t5/network-security/multi-instance-failover/m-p/3950382#M942687 dvalinho 2019-10-30T11:24:21Z
