Why do I see more MAC Host than IP hosts?

[Ed Padilla Jr]

My I am seeing far more MAC Hosts than IP hosts?  I have two ASAs with FirePOWER at the DMZ.  For example, I see HOST IPs 52, and Host (MAC) 3,237.

Hi,

Could you share which version are you running on firepower?

Generally , host profile shows large number of Mac due to arp traffic.

Try purging it and then check if list gets refreshed.

Rate if it helps.

Thanks,

FirePOWER Console 4000 version 6.0.1.  I had done the purging several times.  In addition, I tried to find out the MAC address manufacturer, and nothing.  It seems these MAC addresses are autogenerated.

Hello Team,

If you already tried purging it , then we need to verify it further.

Please open the TAC request so that we can confirm after looking at the behaviour if its a bug or not.

Rate if that helps.

Is there any updates that you received from TAC ?

Nope.   Except the usual scripted response.  Still working on it
