topic ASA 5510 Failover Using Sub-Interface? in Network Security https://community.cisco.com/t5/network-security/asa-5510-failover-using-sub-interface/m-p/531557#M425667 <P>Can you use a sub-interface for statefull failover on the ASA5510? If so, is there any drawbacks to doing so? If not, can you use the management port for failover?</P> Fri, 21 Feb 2020 08:58:17 GMT NotMeHere 2020-02-21T08:58:17Z ASA 5510 Failover Using Sub-Interface? https://community.cisco.com/t5/network-security/asa-5510-failover-using-sub-interface/m-p/531557#M425667 <P>Can you use a sub-interface for statefull failover on the ASA5510?

We did have some restrictions back in earlier code when we were using those ugly physical and logical interface types, but now that we've changed to ints and sub-int (v7.x) there's no restriction. </P><P></P><P>The failover documentation here (<A class="jive-link-custom" href="http://www.cisco.com/univercd/cc/td/doc/product/multisec/asa_sw/v_7_1/conf_gd/failover.htm" target="_blank">http://www.cisco.com/univercd/cc/td/doc/product/multisec/asa_sw/v_7_1/conf_gd/failover.htm</A>) mentions subinterfaces many times.</P></BODY></HTML> Wed, 14 Jun 2006 23:35:13 GMT https://community.cisco.com/t5/network-security/asa-5510-failover-using-sub-interface/m-p/531558#M425668 gfullage 2006-06-14T23:35:13Z
