Security
Firewall This displays the firewall’s current security level.
System Status
System Up
Time
This field displays how long the VMG has been running since it last started up. The VMG
starts up when you plug it in, when you restart it (Maintenance > Reboot), or when
you reset it.
Current Date/
Time
This field displays the current date and time in the VMG. You can change this in
Maintenance> Time Setting.
System Resource
CPU Usage This field displays what percentage of the VMG’s processing ability is currently used.
When this percentage is close to 100%, the VMG 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 QoS; see
Chapter 10 on page 139).
Memory Usage This field displays what percentage of the VMG’s memory is currently used. Usually, this
percentage should not increase much. If memory usage does get close to 100%, the
VMG is probably becoming unstable, and you should restart the device. See Section 37.2
on page 250, or turn off the device (unplug the power) for a few seconds.
NAT Session
Usage
This field displays what percentage of the VMG supported NAT sessions are currently
being used. This field also displays the number of active NAT sessions and the maximum
number of NAT sessions the VMG can support.
Interface Status
Interface This column displays each interface the VMG has.
Status This field indicates the interface’s use status.
For the LAN and Ethernet WAN interfaces, this field displays Up when using the interface
and No Link when not using the interface.
For a WLAN interface, this field displays the enabled (Up) or disabled (Disable) state of
the interface.
For the DSL interface, this field displays Down (line down), Up (line up or connected),
Drop (dropping a call) if you're using PPPoE encapsulation, and No Link when not using
the interface.
For the 3G interface, this field displays Up when using the interface and No Device
when no device is detected in any USB slot.
Rate For the Ethernet WAN and LAN interface, this displays the port speed and duplex setting.
For the DSL interface, it displays the downstream and upstream transmission rate.
For the WLAN interface, it displays the maximum transmission rate or N/A with WLAN
disabled.
For the 3G interface, this field displays Up when a 3G device is installed in a USB slot
and N/A when no device is detected in any USB slot.
