If incase ASA system image is lost or got corrupted we can recover it by booting ASA in ROMMON mode and executing following commands please refer above mentioned diagram. Step 1: Make sure you have assigned the right IP address to the PC which has ASA system image and tftp installed. Step 2: Set the following parameters rommon #0> address 10.1.1.254 rommon #1 > server 10.1.1.1 rommon #2> interface GigabitEthernet0/0 GigabitEthernet0/1 MAC Address: 000f. f775.4b54 rommon #3> file asa801 -k8. bin Step 3: Verify your configured parameters in ROMON mode rommon #4> set ROMMON Variable Settings: ADDRESS=10.1.1.254 SERVER=10.1.1.1 PORT=GigabitEthernet0/0 VLAN=untagged IMAGE=asa801-k8. bin CONFIG= rommon #12> set ROMMON Variable Settings: ADDRESS=10.1.1.50 SERVER=10.1.1.1 ------- output omitted for brevity ----- rommon #13> unset ADDRESS ROMMON Variable Settings: ADDRESS=0.0.0.0 SERVER=10.1.1.1 GATEWAY=0.0.0.0 ------- output omitted f
