Appendix D: SNMP Functions

SNMP (Simple Network Management Protocol) is a widely-used network monitoring and control protocol. Data is passed from a SNMP agent, such as the EtherFast Cable/DSL Firewall Router with 4-Port 10/100 Switch/VPN Endpoint to the workstation console used to oversee the network. The Router then returns information contained in a MIB (Management Information Base), which is a data structure that defines what is obtainable from the device and what can be controlled (turned off, on, etc.).

SNMP functions, such as statistics, configuration, and device information, are not available without third-party Management Software. The EtherFast Cable/DSL Firewall Router with 4-Port Switch/VPN Endpoint is compatible with all HP Openview compliant software.

Appendix E: How to Ping Your ISP’s E-mail & Web Addresses

Virtually all Internet addresses are configured with words or characters (e.g., www.linksys.com, www.yahoo.com, etc.) In actuality, however, these Internet addresses are assigned to IP addresses, which are the true addresses on the Internet. For example, www.linksys.com is actually 216.23.162.142. Type it into your web browser and you will wind up at the Linksys home page every time. There are servers that translate the URL to an IP address; this is called Domain Name System (DNS).

IP and web addresses, however, can sometimes be long and hard to remember. Because of this, certain ISPs will shorten their server addresses to single words or codes on their users’ web browser or e-mail configurations. If your ISP’s e- mail and web server addresses are configured with single words (www, e-mail, home, pop3, etc.) rather than whole Internet addresses or IP addresses, the Router may have problems sending or receiving mail and accessing the Internet. This happens because the Router has not been configured by your ISP to accept their abbreviated server addresses.

The solution is to determine the true web addresses behind your ISPs code words. You can determine the IP and web addresses of your ISP’s servers by “pinging” them.

Important: If you don’t have your ISP’s web and e-mail IP addresses, you must either get them from your ISP or follow these steps prior to connecting your Router to your network.
