Resolving network errors

If you encounter issues when viewing the health system, refer to the following
information and examples.
If a network is not attached to an interface, the health center monitors all ports. It
logs and displays any port failures.
To stop monitoring an unused port, use the attachnw command to attach the
interface that corresponds to that port. After this command is issued, you must
manually mark the displayed error events for the unused port as resolved. You can
use the GUI system details panel to manually mark the events.
Whether a port is monitored depends on the attached network configuration and
the interface that is used for the management network. If an interface is not in use
by an attached network, the interface is monitored if it is used by the management
network.
See the following examples.
