Problem with ARP table from ASA ?
Track your ARP/MAC table changes and so much more

VLAN 515 is a VLAN behind the ASA firewall.
If I look at "Switchports on a VLAN ID" I see VLAN, IP and name.
If I try "Devices in ARP Table by VLAN ID" I get 'No ARP entries on VLAN 515'.
If I look at "Device by IP,MAC or hostname" for that subnet I see no VLAN.
I look at "Device by IP,MAC or hostname" for a specific IP in that VLAN/subnet and see that under "ARP Table" the VLAN entry is blank, but under "Switchport History" it is correctly populated.
From this it looks like the ARP table from the firewall is not getting read/imported properly.
Help?
I must say, this is great! Two days in and I have access to a ton of information that I did not have easy access to before.
