I am using ASAv and some commands are not available as presented bellow:
Cisco Adaptive Security Appliance Software Version 9.9(2)
Firepower Extensible Operating System Version 2.3(1.84)
Device Manager Version 7.9(2)
ciscoasa(config)# int GigabitEthernet0/0
ciscoasa(config-if)# channel-group ?
ERROR: % Unrecognized command
ciscoasa(config)# interface redundant 1
ciscoasa(config-if)# member-interface gi0/2
INFO: security-level, IP address, cts manual, bfd and fail-open configuration are cleared on GigabitEthernet0/2.
ciscoasa(config-if)# member-interface gi0/3
INFO: security-level, IP address, cts manual, bfd and fail-open configuration are cleared on GigabitEthernet0/3.
ciscoasa(config-if)# nameif inside
ERROR: Failed to initialize interface inside
Considering it is more recent image should work no?
