Changing interface names on ASA

db1 — Fri, 21 Feb 2020 16:41:29 GMT

Hi Guys,

I have an ASA 5516 with 2 WAN links, one is named outside and the second name backup. Backup line used to be just 4G dongle to keep us online if main line dies, but it was upgraded to a nice, 300/300 mbit connection. The main line is actually 100/100, so I would like to make the backup line the main line. Of course I could just change the default route, but I don't want to end up with outside interface being a secondary, and backup interface being the main one.

So what would be the easiest way to swap them around? Can I just rename them and all the NAT / ACLs will be renamed as well? Or is this a weekend project...?

Yes, once you rename the interfaces all associated config will change
including nat rules, access-groups, assigned cryptos, etc.
