Does someone know what is the advantage of putting a switch in between them??</P><P></P><P></P><P></P><P></P><P>Thank you.</P> Mon, 11 Mar 2019 21:36:40 GMT https://community.cisco.com/t5/network-security/switch-between-cisco-asa-for-failover/m-p/1767851#M495917 network_user 2019-03-11T21:36:40Z Switch between Cisco ASA for failover https://community.cisco.com/t5/network-security/switch-between-cisco-asa-for-failover/m-p/1767852#M495918 <HTML><HEAD></HEAD><BODY><P>The main advantage is that if you use a direct cable and one of the failover interfaces fails then the other interface on the other firewall goes down as well so it can make troubleshooting difficult. </P><P></P><P>If you use a switch and one interface fails the other is still up because it is connected to the switch. </P><P></P><P>It does not necessarily have to be a dedicated switch in terms of only using that switch for the failover link, as long as the switch you use is not overutilised and is not heavily oversubscribed.</P><P></P><P>Jon</P></BODY></HTML> Tue, 11 Oct 2011 17:49:29 GMT https://community.cisco.com/t5/network-security/switch-between-cisco-asa-for-failover/m-p/1767852#M495918 Jon Marshall 2011-10-11T17:49:29Z Switch between Cisco ASA for failover https://community.cisco.com/t5/network-security/switch-between-cisco-asa-for-failover/m-p/1767853#M495919 <HTML><HEAD></HEAD><BODY><P> Thanks Jon! </P></BODY></HTML> Wed, 12 Oct 2011 19:16:34 GMT https://community.cisco.com/t5/network-security/switch-between-cisco-asa-for-failover/m-p/1767853#M495919 network_user 2011-10-12T19:16:34Z
