ZyWALL 2 Plus User’s Guide
60 Chapter 2 Introducing the Web Configurator
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. The gateway is usually the device that connects the
ZyWALL to the Internet.
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 LAN.
Port Status 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 port, it displays Down when the link is not ready or has failed.
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.
RSTP Path Cost This is the cost of transmitting a frame from the root bridge to the corresponding
port.
