ZyXEL Communications P-660RU-T V2 User Manual

Chapter 13 Maintenance

P-660RU-T v2 User’s Guide

The following table describes the labels in this 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

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)
