How to see neighbor in cisco ASA ?

Hi experts, i'm very new in cisco security world.

So my company has topology so many end devices -> so many nexus -> 1 asa.

I have a task to find device hostname and its connected port in the nexus. 

The only clue is just from device ip address. 

For example device with ip 10.86.34.5 is connected with which port in nexus, and what is the hostname of 10.86.34.5. Any idea?

i have tried to sh arp ini asa and find the end devices ip address in there, but i stucked becauase i can not sh cdp neighbor ini asa.

Unfortunately there isn't any available on ASA to tell you what device is directly connected to it, there is no "show cdp neighbor" on ASA unfortunately.

 

You can check the ARP table and see what the next hop is, but that would only give you the Layer 3 device, as there could be a switch in between as well.

Hi,

You can use the third party tool as Advanced IP scanner or Ping with Hostname resolution to get hostname (If it is defined or updated in the DNS entry). The CDP is not avaiable on the ASA.
