Resolving Management Connection Problems Troubleshooting
o On directly accessed NE, MetaASSIST View tries to connect to the NE and
displays the following tooltip when the cursor is located on the NE: 'Started
Connecting...'. Re-connect with correct IP address.
o On in-directly accessed NE (subtended via HSL NE), MetaASSIST View tries to
connect to the NE but fails to connect. In this case, the NE will be displayed in
the NEs linked via HSL pane. Reconfigure the parameters on the ML NE using
this pane and then re-connect via this pane.
Access is not granted by IP Access Control feature
In this case, MetaASSIST View tries to reconnect indefinitely. Resolve the problem and
MetaASSIST View will reconnect automatically.
In this case, you need to add your IP address to the IP Access Control List with the
Telnet protocol specified as enabled for connection or connect through the Craft port
and disable IP Access Control. IP Access Control feature is enabled on ML device
and the IP address of your host (PC/Workstation) is not in the IP Access Control List.
