    Diagnostics and Troubleshooting Performance Issues – Viewing Network Statistics The previous sections of this document examined connectivity issues, i.e., the inability to Ping the router. Table 6-9 presents information on viewing DSLAM statistics screens to examine performance issues. These statistic screens give information related to the number of packets transmitted and received on an interface as well as any packet failures.

    Download Code Download Code When you are attempting to download to the DSL cards, refer to Status Options, in Chapter 5, 8310 MVL and 8510 RADSL Card Configuration . In general, the following describes what to expect when you have initiated a download from the configuration menu.
  • Page 97 Traps DSL Card Traps Traps are configured via a Telnet or terminal session. The addition or removal of a card or another hardware component within the Hotwire DSLAM system causes a trap to be generated. These traps indicate a configuration change notification (CCN) of a card (a hardware replacement or a software upgrade).

In a subnetted network, the host portion of an IP address is split into a subnet portion and a host portion using an address (subnet) mask. This allows a site to use a single IP network address for multiple physical networks.
