Best way to restore config on standby ASA 5515x

[eddie.sardinha]

Hello All, 

What is the best way to restore a config that I backed up using TFTP on a standby ASA 5515x, both models are the same.  I just want to have the config on the standby ASA in the event of a failure?    I know there are USB ports on the back of the ASA, could i just plug in a USB with the backup file and restore and if so how?

Thanks,

Sure - as long as it is formatted FAT-32.

The ASA will see it as disk1 when inserted. disk0 is the internal comapct flash.

Just copy the config from disk1/<filename> to disk0:/startup-config

You could also just connect them in an HA pair and keep the failover near realtime.

great!  I was looking at HA but I don't have multiple circuits.  Could I do HA and then if it fails just unplug the  WAN from ASA1 and plug it into ASA2?  I think that would defeat the purpose but just asking.

You could put the Ethernet from the WAN into a switch and make a small L2 VLAN with just that connection plus the two ASAs' outsdide interfaces.
