topic Problem with ASDM using failover in Network Security https://community.cisco.com/t5/network-security/problem-with-asdm-using-failover/m-p/1511497#M600104 <P>I have a problem with ASDM of&nbsp; two ASA 5520 when these are working with failover because if the primary is active and the secondary is passive, I can't access with ASDM&nbsp; while if the primary is passive and the secondary is active I can access with ASDM, it's worth noting that both have images asdm-625-53 and asa823-k8. Please if someone knows what is the cause of this behavior help me.
