A UPnP device can dynamically join a network, obtain an IP address, convey its capabilities and learn about other devices on the network. In turn, a device can leave a network smoothly and automatically when it is no longer in use. 11. 1. 1 How do I know if I'm using UPnP? UPnP hardware is identified as an icon in the Network Connections folder (Windows XP). Each UPnP compatible device installed on your network will appear as a separate icon. Selecting the icon of a UPnP device will allow you to access the information and properties of that device. 11. 1. 2 NAT Traversal UPnP NAT traversal automates the process of allowing an application to operate through NAT. UPnP network devices can automatically configure network addressing, announce their presence in the network to other UPnP devices and enable exchange of simple product and service descriptions. NAT traversal allows the following: • Dynamic port mapping • Learning public IP addresses • Assigning lease times to mappings Windows Messenger is an example of an application that supports NAT traversal and UPnP. See the Network Address Translation (NAT) Screens chapter for further information about NAT. 11. 1. 3 Cautions with UPnP The automated nature of NAT traversal applications in establishing their own services and opening firewall ports may present network security issues. Network information and configuration may also be obtained and modified by users in some network environments. Chapter 11 Universal Plug-and-Play (UPnP) 94 Prestige 660RU-Tx Series User’s Guide All UPnP-enabled devices may communicate freely with each other without additional configuration. Disable UPnP if this is not your intention. 11. 2 UPnP and ZyXEL ZyXEL has achieved UPnP certification from the Universal Plug and Play Forum Creates UPnP™ Implementers Corp. DESCRIPTION 109 Chapter 12 Maintenance Prestige 660RU-Tx Series User’s Guide Table 25 System Status (continued) LABEL IP Subnet Mask Default Gateway VPI/VCI LAN Information MAC Address IP Address IP Subnet Mask DHCP DHCP Start IP DHCP Pool Size Show Statistics This is the MAC (Media Access Control) or Ethernet address unique to your Prestige. This is the WAN port DHCP role - Server, Relay (not all Prestige models) or None. Click Show Statistics to see the performance statistics such as number of packets sent and number of packets received for each port. This is the Virtual Path Identifier and Virtual Channel Identifier that you entered in the first Wizard screen. 12. 2. 1 System Statistics Click Show Statistics in the System Status screen to open the following screen. Read-only information here includes port status and packet specific statistics. Also provided are "system up time" and "poll interval(s)". The Poll Interval(s) field is configurable. Figure 50 System Status: Show Statistics Chapter 12 Maintenance 110 Prestige 660RU-Tx Series User’s Guide The following table describes the labels in this screen. Table 26 System Status: Show Statistics LABEL System up Time CPU Load LAN or WAN Port Statistics Link Status Upstream Speed Node-Link Interface Status DESCRIPTION This is the elapsed time the system has been up. 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. This field displays the number of bytes transmitted in the last second. Click this button to apply the new poll interval you entered in the Poll Interval field above. Click this button to halt the refreshing of the system statistics. Downstream Speed This is the downstream speed of your Prestige. TxPkts RxPkts Errors Tx B/s Rx B/s Up Time Collisions Poll Interval(s) Set Interval Stop 12. 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. [. . . ] The required fields in a command are enclosed in angle brackets <>. For example, sys filter netbios config <type> <on|off> means that you must specify the type of netbios filter and whether to turn it on or off. Command Usage A list of valid commands can be found by typing help or ?Type exit to return to the SMT main menu when finished.
