Resolution

The following trap proceeds if you have VLANs shutdown but still show up in the vmmembership table. For example,

SolarWinds normal Topology polling polls all Layer 2 VLAN information regardless if it is shutdown. Refer to What object IDs (OIDs) does the Orion Platform poll for network topology information.

cExtSnmpTargetAuthInetAddr = "SolarWinds Poller IP ADDRESS"

cExtSnmpTargetAuthInetType = 1

authAddr = "SolarWinds Poller IP ADDRESS"

snmpTrapOID = SNMPv2-MIB:authenticationFailure

sysUpTime = 71 days 21 hours 25 minutes 50.85 second

The only current known workaround is to filter Traps or shut off these failure Traps from being sent from the device.
