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. Refer to Table 5-2, Physical Layer Options, in Monitoring the Hotwire DSLAM of the Hotwire Management Communications Controller (MCC) Card, IP Conservative, User's Guide for details on the Statistics screens.

Examine Slow	Screen B-B-B. Slow performance could result from errors seen on
Performance	this screen.
	Make sure the DSLAM and IPC are both operating at either full- or
	half-duplex mode. On the DSLAM, go to screen A-B-A. On the IPC,
	enter 10/100cfg. If operating at full-duplex, a hub should not be
	used.
	Check the Ethernet Statistics screen for excessive Cycle
	Redundancy Check (CRC) errors, a bad connection, or a bad cable
	(see DSL Monitoring Physical Layer Screens in Chapter 5,
	Monitoring the Hotwire DSLAM ).

Examine	Screen B-B-B. Minimal collisions are acceptable if packets are not
Collisions	being discarded. Excessive collisions could result from forcing too
	much data over a single Ethernet.
	1. Determine if your network is too large or long (single Ethernet
	cable or end-to-end cable).
	2. Check to see if there are too many repeaters.
	3. Check to see if there are too many users on a single Ethernet.
	Intranetworking communication problems:
	1. Verify that the internetworking network cables meet IEEE
	standards for local Ethernet networks.
	2. Check cable connections to DSLAM and other devices in the
	network.
	3. Determine whether or not your system is the only one in the
	network with a problem.
