DESCRIPTION
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.
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.
The first number shows how many megabytes of the flash the ZyWALL is using.
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.
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.
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.
This is the IP address and subnet mask of your ZyWALL in dotted decimal notation.
This is the gateway IP address.
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.
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).
This is the predefined interval that a bridge waits to get a Hello message (BPDU)
from the root bridge.
This is the forward delay interval.
This is the port type. Port types are: WAN (or WAN1, WAN2), LAN, Wireless Card,
DMZ and WLAN Interface.
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.
This is the RSTP status of the corresponding port.
