Chapter 5 Network Map and Status Screens Table 5 Status Screen (continued) LABEL DESCRIPTION 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 135). 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 38.2 on page 245, 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 NoLink 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 NoLink when not using the interface. Rate For the 3G interface, this field displays Up when using the interface and NoDevice when no device is detected in any USB slot. 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. VMG3925-B10B User's Guide 56
