topic ACS v2.6 Availability During Replication in Network Access Control https://community.cisco.com/t5/network-access-control/acs-v2-6-availability-during-replication/m-p/39807#M10534 <P>Will Cisco ACS v2.6 for WinNT/2000 reject a connection request from a NAS while the database is down for replication, or will it accept the request and just not be able to service the authentication? I'm trying to verify that the NAS (an iPass RoamServer in this instance) will fail over to the secondary ACS as desired. Thanks.</P> Fri, 21 Feb 2020 17:57:15 GMT bvavpeti 2020-02-21T17:57:15Z ACS v2.6 Availability During Replication https://community.cisco.com/t5/network-access-control/acs-v2-6-availability-during-replication/m-p/39807#M10534 <P>Will Cisco ACS v2.6 for WinNT/2000 reject a connection request from a NAS while the database is down for replication, or will it accept the request and just not be able to service the authentication?
