2.4.1 Status: Bandwidth Status

This is the same screen discussed in Figure 93 on page 197.

IP Subnet Mask This is the LAN port IP subnet mask.

DHCP This is the WAN port DHCP role - Server, Relay or None.

Security This section is not available if you use the user password to log in.

Firewall This displays whether or not the ZyXEL Device’s firewall is activated.

Content Filter This displays whether or not the ZyXEL Device’s content filtering is activated.

System Status

System Uptime This is the total time the ZyXEL Device has been on.

Current Date/Time This field displays your ZyXEL Device’s present date and time.

System Mode This displays whether the ZyXEL Device is functioning as a router or a bridge.

CPU Usage This number shows how many kilobytes of the heap memory the ZyXEL Device 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 bar displays what percent of the ZyXEL Device's heap memory is in use. The

bar turns from green to red when the maximum is being approached.

Memory Usage This number shows the ZyXEL Device's total heap memory (in kilobytes).

The bar displays what percent of the ZyXEL Device's heap memory is in use. The

bar turns from green to red when the maximum is being approached.

Interface Status

Interface This displays the ZyXEL Device port types.

Status This field displays Down (line is down), Up (line is up or connected) if you're using

Ethernet encapsulation and Down (line is down), Up (line is up or connected), Idle

(line (ppp) idle), Dial (starting to trigger a call) and Drop (dropping a call) if you're

using PPPoE encapsulation.

Rate For the LAN ports, 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.

Simultaneous transmissions over the same port (Full-duplex) essentially double

the bandwidth.

For the WAN port, it displays the downstream and upstream transmission rate.

Summary This section is not available if you use the user password to log in.

Bandwidth Status Use this screen to view the ZyXEL Device’s bandwidth usage and allotments.

Packet Statistics Use this screen to view port status and packet specific statistics.

VPN Status Use this screen to view the status of any VPN tunnels the ZyXEL Device has

negotiated.
