I have been working on a project to map out my organization's network infrastructure. For the networking devices (we are a Cisco shop) I have been running the show cdp neighbors command to see how everything is connected and through which interface. I am noticing that our ASA is not showing up in the output of these commands (it is connected to a Cisco switch). I ran a command list via show ? and CDP does not show up as an option.

My question is this: is there a command similar to show cdp neighbors that will show to which devices the ASA is connected?

The ASA's do not support CDP. About the best you can do is to look at the MAC address of the interface and then look through the switch mac-address or CAM tables.
