Adding a device in Topology as a Generic SNMP Device is a sufficient option for L3 devices that are modeled only to collect ARP table (IP to MAC) information and will not be placed under enforcement. If ports will be enforced, this option is not recommended.
Scope Version: 8.x Solution
Requirements: The device must respond to either of the following OIDs:
ipNetToMediaTable (1.3.6.1.2.1.4.22)
atTable (SNMPv2-SMI::mib-2.3.1.1)
This can be verified by performing a snmpwalk (either using the CLI snmpwalk tool or some other machine with SNMP tools).
snmpwalk -v 3 -u <username> -l <AuthPriv or NoAuthPriv> -a <MD5 or SHA> -A <password> -x <DES or AES> -X <password> <device ip_address> ipNetToMediaTable
snmpwalk -v 3 -u <username> -l <AuthPriv or NoAuthPriv> -a <MD5 or SHA> -A <password> -x <DES or AES> -X <password> <device ip_address> atTable
For Generic SNMP Devices, the ipNetToMediaTable is queried first in order to pull ARP table information during a L3 Poll. If there is no response, the address translation table (atTable) is attempted.
Procedure:
1. Right click the model displaying the ? iconand select Set Device Mapping.
2. In the window that appears, select Model this Device as a Generic SNMP Device.
