System Time
This field displays your ZyWALL’s present
date (in yyyy-mm-dd format) and time
(in hh:mm:ss format) along with the difference from the Greenwich Mean Time
(GMT) zone. The difference from GMT is based on the time zone. It is also
adjusted for Daylight Saving Time if you set the ZyWALL to use it. Click the field
label to go to the screen where you can modify the ZyWALL’s date and time
settings.

field label to go to the screen where you can configure the ZyWALL as a router or a
bridge.

System
Resources
Flash
The first number shows how many megabytes of the flash the ZyWALL is using.
Memory
The first number shows how many megabytes of the heap memory the ZyWALL is
using. Heap memory refers to the memory that is not used by ZyNOS (ZyXEL
Network Operating System) and is thus available for running processes like NAT,
VPN and the firewall.
The second number shows the ZyWALL's total heap memory (in megabytes).
The bar displays what percent of the ZyWALL's heap memory is in use. The bar
turns from green to red when the maximum is being approached.
Sessions
The first number shows how many sessions are currently open on the ZyWALL.
This includes all sessions that are currently traversing the ZyWALL, terminating at
the ZyWALL or initiated from the ZyWALL
The second number is the maximum number of sessions that can be open at one
time.
The bar displays what percent of the maximum number of sessions is in use. The
bar turns from green to red when the maximum is being approached.
CPU
This field displays what percentage of the ZyWALL’s processing ability is currently
used. When this percentage is close to 100%, the ZyWALL is running at full load,
and the throughput is not going to improve anymore. If you want some applications
to have more throughput, you should turn off other applications (for example, using
bandwidth management.
