| LABEL | DESCRIPTION |
| System Time | This field displays your ZyWALL’s present date (in |
|
| (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. |

|
| 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. |
|
|
|
| Network Status |
|
|
|
|
| IP/Netmask | This is the IP address and subnet mask of your ZyWALL in dotted decimal |
| Address | notation. |
|
|
|
| Gateway IP | This is the gateway IP address. |
| Address |
|
|
|
|
| Rapid Spanning | This shows whether RSTP (Rapid Spanning Tree Protocol) is active or not. The |
| Tree Protocol | following labels or values relative to RSTP do not apply when RSTP is disabled. |
|
|
|
| Bridge Priority | This is the bridge priority of the ZyWALL. The bridge (or switch) with the lowest |
|
| bridge priority value in the network is the root bridge (the base of the spanning |
|
| tree). |
|
|
|
| Bridge Hello | This is the interval of BPDUs (Bridge Protocol Data Units) from the root bridge. |
| Time |
|
|
|
|
| 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, LAN, DMZ and WLAN. |
