Neighbor Scanning on Cisco ASA Firewall does not work

Updated October 20, 2017

Overview

Neighbor Scanning on Cisco ASA firewalls does not work.

Environment

  • IPAM 4.5.2 and earlier

Details

The Cisco ASA firewall does not support the required OIDs.

 

IPAM first checks if the device is capable of SNMP and supports ARP table:
To check whether SNMP is available IPAM uses these OIDs:
    • SysContact                 "1.3.6.1.2.1.1.4.0" iso.org.dod.internet.mgmt.mib-2.system.sysContact.0

 

To check whether the ARP table is available:
    • IPNetToMediaTable          "1.3.6.1.2.1.4.22" iso.org.dod.internet.mgmt.mib-2.ip.ipNetToMediaTable

 

The IPNetToMediaTable is pulled for client information. If the device supports this table, then IPAM can work with it.

 

IPNetToMediaTable is not present on the ASA.
