10.6 Event Action Problems

I see "connection fail" when I test an e-mail notification action.
Make sure you have entered a correct IP address or domain name for the mail server in the

Maintenance > Server screen.
Make sure you have entered an existing e-mail address for the Sender Mail setting.

10.7 VLAN/Port Management Problems

I cannot see some switches in the VLAN/Port Management screen.
At the time of writing, VLAN Management and Port Management are not available for all switches.
Check the supported switch models listed in the release note.

10.8 Lose Connection Problems

The ENC begins to respond extremely slowly.
You may have lost the connection with the ENC due to one of the following reasons:
• The network is busy. Try to do your operation again later.
• The ENC server is busy or disconnected. Try to do your operation again later.
• An administrator disconnected your session. Try to log in to the ENC again later. Contact the ENC
administrator if this happens again.
• Another person used the same account to log in to the ENC. Two or more users may have the
same account but only one account can log in at the same time. The first user will be logged out
(without notification) when a second user logs in, in this case. Try to log in to the ENC again later.
It is suggested that every user has an unique account.
