but it will be show less size when you will download the image. Because these are modified for virtual environment.Ībove mentioned IOS size is the actual size of image. So these will not work on hardware machine. NOTE: These all below IOS are specifically designed and modified for GNS3 and EVE-NG.

The failover could be stateless and stateful, the above configuration configured G0/1 as stateful failover interface. It could blank your active configuration if the order is not correct.Īlso, whenever there is an configuration update, it should be done on the primary / active unit, so the change could be synched to the standby. The failover configuration order is important. The failover ASA pair should have identical hardware platform, software and license to achieve working failover.
