Adding a Device in Topology as a Generic SNMP Device
Network Sentry 8
Network Sentry 8 This option is sufficient 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 is not a recommended option.
The device must respond to either of the following OIDs: ipNetToMediaTable (22.214.171.124.126.96.36.199) atTable (SNMPv2-SMI::mib-188.8.131.52) This can be verified by performing a snmpwalk (either using Network Sentry snmpwalk tool or some other machine with SNMP tools). Commands for Network Sentry or Another Linux Platform. SNMP version 1 or 2 snmpwalk -v 1 -c ipNetToMediaTable snmpwalk -v 1 -c atTable SNMP version 3 snmpwalk -v 3 -u -l -a -A -x -X ipNetToMediaTable snmpwalk -v 3 -u -l -a -A -x -X atTable For Generic SNMP Devices, Network Sentry attempts to pull ARP table information during a L3 Poll by first querying ipNetToMediaTable. If there is no response, Network Sentry attempts to read the address translation table (atTable).
