To ensure the NE security, you need to disable the unused interfaces on the NE. The Web LCT allows you to enable or disable security access for NEs.
Controlling Communication Between NE and Web LCT Through Ethernet Port
An NE can be connected to the Web LCT through an Ethernet port. By default, an NE allows access from the Web LCT through an Ethernet port. This operation enables you to query and set the Ethernet access function for an NE.
Controlling Communication Between NE and LCT
For NE operation security, NEs are managed by the U2000 under normal circumstances. But under special circumstances, you need to use the U2000 LCT or Web LCT to commission an NE. You can turn on LCT access for the NE on the U2000.
