The following table describes the labels in this screen.

13.3

DHCP Table Screen

DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual

clients to obtain TCP/IP configuration at start-up from a server. You can configure the ZyXEL

Device as a DHCP server or disable it. When configured as a server, the ZyXEL Device

provides the TCP/IP configuration for the clients. If set to

None

, DHCP service will be

disabled and you must have another DHCP server on your LAN, or else the computer must be

manually configured.

Table 27

System Status: Show Statistics

LABEL

DESCRIPTION

System up Time

This is the elapsed time the system has been up.

CPU Load

This field specifies the percentage of CPU utilization.

LAN or WAN Port

Statistics

This is the WAN or LAN port.

Link Status

This is the status of your WAN link.

Upstream Speed

This is the upstream speed of your ZyXEL Device.

Downstream Speed

This is the downstream speed of your ZyXEL Device.

Node-Link

This field displays the remote node index number and link type. Link types are

PPPoA, ENET, RFC 1483 and PPPoE.

Interface

This field displays the type of port.

Status

For the WAN port, this displays the port speed and duplex setting if you're using

Ethernet encapsulation and

Down

(line is down),

Idle

(line (ppp) idle),

Dial

(starting to trigger a call) and

Drop

(dropping a call) if you're using PPPoE

encapsulation.

For a LAN port, this shows 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.

TxPkts

This field displays the number of packets transmitted on this port.

RxPkts

This field displays the number of packets received on this port.

Errors

This field displays the number of error packets on this port.

Tx B/s

This field displays the number of bytes transmitted in the last second.

Rx B/s

This field displays the number of bytes received in the last second.

Up Time

This field displays the elapsed time this port has been up.

Collisions

This is the number of collisions on this port.

Poll Interval(s)

Type the time interval for the browser to refresh system statistics.

Set Interval

Click this button to apply the new poll interval you entered in the

Poll Interval

field above.
