Network Adapter Health

Microsoft.Solaris.10.NetworkAdapter.Health.Monitor (UnitMonitor)

Knowledge Base article:

Summary

The network adapter has been disconnected from the network and no longer has network connectivity.

Network adapter health is determined by identifying network adapters that are Up or Running (as defined by the device flags: IFF_RUNNING and IFF_UP of the ioctl: SIOCGIFFLAGS). If a network adapter that was identified as Up or Running is no longer Up or Running, it is considered unhealthy.

Configuration

Parameter

Default Value

Interval (seconds)

300

Overrides can be used to change the parameter values defined above for all instances or for specific instances or groups.

Causes

Your computer's network adapter lost its connection to the network.

The adapter's connection to the network can be lost if you remove a network cable from your network adapter or if you are roaming between wireless access points with a mobile system. Other possible causes include network issues, firewall issues, or a malfunction of the network adapter or its driver.

Resolutions

If your computer is connected to the network by cable, confirm that the cable is plugged in properly. If you have a wireless network connection, confirm that you have a signal and the proper credentials for the wireless network.

If the network connection is working properly, check the following possible causes and take corrective action:
