After synchronization is complete, check whether the interface to be modified is listed in the query result area.
For example, assume that the user is assigned the right to modify interface descriptions of the Eudemon 8000E. On the Operation Rights tab page to the right of the NMS User Management navigation tree, check whether the user has the FW and VPN Series Operator Operation Set or FW and VPN Series Maintainer Operation Set right.
l The NE connection is abnormal.
l The interface to be modified does not exist.
l The user does not have the related operation right.
