IPAM Neighbor discovery with Cisco ASA Firewalls

Hi all, does anybody knows if neighbor discovery or IP address scan is supported on Cisco ASA firewalls?

I bought this solution a year ago, and at that time after the deployment and confguration of the tool i've found that subnets routed on firewalls are not beeing scanned.

I read somewhere on the web that this is because the OID implementation on Cisco ASA firewalls does not have the ARP info.

I wounder if anybody has any experience over this scenario?

this has a solution already? or in the future?

thanks in advance and regards
