At a customer site where I work we run two servers with ACS. Our routers and switches attempt to authenticate with one server and if they get no response then they attempt to authenticate with the redundant server. It works very well for us.</P><P></P><P>HTH</P><P></P><P>Rick</P></BODY></HTML> Tue, 06 Sep 2005 12:14:10 GMT https://community.cisco.com/t5/network-access-control/acs-redundancy/m-p/461532#M428533 Richard Burts 2005-09-06T12:14:10Z Re: ACS Redundancy https://community.cisco.com/t5/network-access-control/acs-redundancy/m-p/461533#M428534 <HTML><HEAD></HEAD><BODY><P>You may want to take a look at the Replication options under </P><P></P><P>System Config --&gt; CiscoSecure Database Replication</P><P></P><P>This will allow the redundant server to be kept in step with the master server.</P><P></P><P>It is also worth considering the second server not to simply provide redundancy but also to take some of the load.</P><P></P><P>Half devices pointing at server A, failing back to Server B</P><P>Tht other half of devices pointing at server B, failing back to Server A</P><P></P><P></P><P></P><P></P></BODY></HTML> Fri, 16 Sep 2005 09:47:51 GMT https://community.cisco.com/t5/network-access-control/acs-redundancy/m-p/461533#M428534 andrewclymer 2005-09-16T09:47:51Z
