I want to identify then configure the management interface, however the output shows there is no interface Management. How can the management interface be found? Is it missing from hardware or is it missing configuration?

It's just your ASA doesn't have a dedicated management port.

Then you must setup one of your ASA interfaces to become management interface.

The ASA 5510 and higher adaptive security appliance includes a dedicated management interface called Management 0/0, which is meant to support traffic to the security appliance. However, you can configure any interface to be a management-only interface using the management-only command.

The output you provided is from real device or from GNS3 simulator?

  • GNS3 / Qemu emulator. Management 0/0 doesn't show up anywhere in show-running-config. – T. Webster May 06 '13 at 09:46
  • Maybe GNS3 doesn't have any dedicated Management 0/0 port. My GNS3 provides the same output with you. Do you try to config ethernet interface to become management interface? – cuonglm May 06 '13 at 10:37
