Chapter 2 Introducing the Web Configurator

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

proprietary Network Operating System design.

Device Mode

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

Firewall

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

System Time

This field displays your ZyWALL’s present

 

date and time 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.

Memory

The first number shows how many kilobytes 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 kilobytes). 
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

•

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.

Network Status

IP Address

This is the IP address of your ZyWALL in dotted decimal notation.

Subnet Mask

This is the IP subnet mask of the ZyWALL.

Gateway IP 

Address

This is the gateway IP address.

Rapid Spanning 

Tree Protocol

This shows whether RSTP (Rapid Spanning Tree Protocol) is active or not. The 

following labels or values relative to RSTP do not apply when RSTP is disabled. 

Bridge Priority

This is the bridge priority of the ZyWALL.

Bridge Hello Time This is the 

interval of BPDUs (

Bridge Protocol Data Units

) from the root bridge.

Bridge Max Age

This is the predefined interval that a bridge waits to get a Hello message (BPDU) 

from the root bridge.

Forward Delay

This is the forward delay interval.

Bridge Port

This is the port type. Port types are: WAN (or WAN1, WAN2), LAN, Wireless Card, 

DMZ and WLAN Interface.

Port Status

For the WAN, LAN, DMZ, and WLAN Interfaces, this displays the port speed and 

duplex setting. For the WAN port, it displays Down when the link is not ready or has 

failed. For the wireless card, it displays the transmission rate when a wireless LAN 

card is inserted and WLAN is enabled or Down when a wireless LAN is not inserted 

or WLAN is disabled.

RSTP Status

This is the RSTP status of the corresponding port.

RSTP Active

This shows whether or not RSTP is active on the corresponding port.

RSTP Priority

This is the RSTP priority of the corresponding port.
