This section explains the confirmation procedure of L2 switch status.
Use the following procedure to confirm the status of the L2 switch.
Select the network device on which the status icon has changed from normal to another using the network device tree.
Select the [Resource Details] tab.
Confirm the displayed detailed information.
When there is a link of [Launch Network Device Web UI] in [Hardware Details]
Click the link and start the L2 switch management screen.
Confirm event logs or status from the started management window, and check the error detected by the L2 switch.
When there is no link of [Launch Network Device Web UI] in [Hardware Details]
Confirm the following information displayed in the Main Panel.
The status of the L2 switch is displayed.
When the status is something other than "normal", it indicates that an error might have occurred.
The status of the port of the L2 switch is displayed.
When the status is something other than "up", it indicates that a port error might have occurred.
Take corrective action based on the results of L2 switch status checks.
When an error is detected on an L2 switch or an event log is output
The infrastructure administrator must confirm if the specifications of configuration scripts or parameter files used in auto-configuration are correct.
When it is possible that the hardware has failed, in cases where the L2 switch device status is "unknown" or the link status is "down" that is not intended by infrastructure administrator.
The infrastructure administrator must request confirmation of the status of the L2 switch from the network device administrator. The network device administrator should request a hardware maintenance person to take corrective action when hardware has failed.
Take corrective action based on the results of checked scripts and files.
When there are no errors in the scripts or settings in files checked in 4.
Confirm with the administrator of the network device that the L2 switch configuration has not been modified, since an unexpected definition modification may have been made.
When there are errors in the scripts or settings in files checked in 4.
The infrastructure administrator will log in to the L2 switch directly, delete the failed configurations, and modify error scripts or files.
Take corrective action based on the check results if definitions have been modified.
When the network device administrator has not modified the configuration
Extract the L2 switch definitions and check the content. When inappropriate settings have been configured, log in to the L2 switch directly, and modify the definitions.
When a network device administrator has modified the configuration
Check that the configuration modification is necessary.
When the configuration modification is not necessary
The infrastructure administrator must log in to the L2 switch directly, and delete or modify the problem-causing configuration.
When configuration modifications were necessary based on the system operation policy
Review if the details of scripts and parameter files are based on the operation policy.

For details on L2 switch operations (login, status confirmation. definition extraction, definition modification), refer to the manuals of L2 switches.
