LABEL

DESCRIPTION

Firmware Version

This is the ZyNOS Firmware version and the date created. ZyNOS is ZyXEL's

 

proprietary Network Operating System design. Click the field label to go to the

 

screen where you can upload a new firmware file.

 

 

Up Time

This field displays how long the ZyWALL has been running since it last started up.

 

The ZyWALL starts up when you turn it on, when you restart it (MAINTENANCE >

 

Restart), or when you reset it (see Section 2.3 on page 53).

 

 

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.

 

 

Device Mode

This displays whether the ZyWALL is functioning as a router or a bridge. Click the

 

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

 

a bridge.

 

 

Firewall

This displays whether or not the ZyWALL’s firewall is activated. Click the field

 

label to go to the screen where you can turn the firewall on or off.

 

 

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.

 

 

Interfaces

This is the port type.

 

Click "+" to expand or "-" to collapse the IP alias drop-down lists.

 

 

Status

For the LAN, DMZ and WLAN ports, this displays the port speed and duplex

 

setting. Ethernet port connections can be in half-duplex or full-duplex mode. Full-

 

duplex refers to a device's ability to send and receive simultaneously, while half-

 

duplex indicates that traffic can flow in only one direction at a time. The Ethernet

 

port must use the same speed or duplex mode setting as the peer Ethernet port in

 

order to connect.

 

For the WAN and Dial Backup ports, it displays the port speed and duplex setting

 

if you’re using Ethernet encapsulation and Down (line is down or not connected),

 

Idle (line (ppp) idle), Dial (starting to trigger a call) or Drop (dropping a call) if

 

you’re using PPPoE encapsulation.

 

 

IP/Netmask

This shows the port’s IP address and subnet mask.
