nicTest
Module: COMPEX-IN3000
OID (symbolic): COMPEX-IN3000::nicTest
OID (numeric): 1.3.6.1.4.1.426.1.15.4
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This variable is used to run a diagnostic test on the ethernet controller.
To run the test this variable must be set to runTest(3). Setting this to any other value will result in an error.
What is nicTest?
This read-write integer triggers a built-in diagnostic self-test of the router's Ethernet controller chip, and reads back as testPass or testFailed once it completes. An administrator sets it to run a hardware health check on the NIC when a device seems to be dropping Ethernet frames or refusing to link up, without needing physical access to the unit. For example, after noticing intermittent LAN dropouts on an IN3000, a technician sets nicTest to runTest(3) via SNMP and polls it a few seconds later to confirm it returns testPass rather than testFailed.
