Teamed Network Interface (Basic) Connection Status Event triggered monitor

Dell.WindowsServer.TeamedBasicNetworkInterfaceUnitEventUnitMonitor (UnitMonitor)

Unit Monitor to calculate the Teamed Network Interface Status.

Knowledge Base article:

Summary

This Health Monitor monitors the state of Teamed network interfaces on the Dell Server. The status can be one of the following three types:

Success: If the status is success, all network interfaces has returned to a normal value.

Warning: If the status is warning, one or more network interface is noncritical.

Critical: If the status is critical, one or more network interface status is critical.

Causes

Warning: A Warning status is displayed if one or more teamed network interfaces are in warning state. This happens when the network interface status is initializing or is in the process of connecting to the network.

Critical: A Critical status is displayed if one or more teamed network interface in the specified system is in critical state. This happens when the network cable is not connected, NIC hardware fails, network link is down, connection is disabled manually by the user, or has limited or no connectivity to network.

Resolutions

Perform the following steps for the Warning and Critical status:

Warning: A Warning status indicates one or more teamed network interfaces is initializing or is in the process of connecting to the network. Wait for some time and retry.

Critical: A Critical status indicates limited or no network connectivity for one or more physical network interfaces. If the problem persists, check if the network cable is connected, Network interface drivers are configured properly, trouble shoot for any NIC hardware failures from the Windows Event Log and check if the network configuration is correct.
