21.16 Introducing Vantage CNM
Vantage CNM (Centralized Network Management) is a browser-based global management
solution that allows an administrator from any location to easily configure, manage, monitor
and troubleshoot ZyXEL devices located worldwide. See the Vantage CNM User's Guide for
details.
If you allow your ZyWALL to be managed by the Vantage CNM server, then you should not
configure the ZyWALL (using either the web configurator, SMT menus or commands)
without notifying the Vantage CNM administrator.
