Figure 61. Management – System Log – Configure
Configure the System Log option. There’re 8 levels of Log Level and Display
Level, Emergency, Alert, Critical, Error, Warning, Notice, Informational,
Debugging. The Log Level implies that what log level is applied to AH4021 to
do the log. The Display Level would just show the users the log message that
they want to know. As a result, Display Level was just a subset of the retrieved
from the total log message which was logged according to the setting of the
Log Level. If the “Mode” is set to “Remote” or “Both”, the log messages
would be sent to the specified UDP port of the specified log server.

Access Control
The AH4021 browser management tool is protected by a security password.
System Administrator could set the password for three accounts: admin,
support, and user. Also, an Access Control list can be defined in “IP
Addresses”. User from the allowed IP address can only access the AH4021.
The “Services” list the service daemons which can be enabled for LAN side,
WAN side, or both. It supports the ACL capability which can assign at least 16
IP addresses for management, and AH4021 can be configured and managed by
ACL IP addresses only.
