configuration model easier to understand. Based on the preceding
advantages, you are advised to set the NAC mode to unified.

In versions earlier than V200R007C00, after the NAC mode is switched,
you need to manually save the configuration file and restart the AC to
make the new NAC mode take effect. In V200R007C00 and later
versions, after the NAC mode is switched, the AC automatically saves
the configuration file and restarts.
