If the problem is still not isolated

3Check for any relevant messages in the Trap window. Use of this tool is described in “Trap Window”, p. 37.

4Check for any relevant messages in the System window.

The System Log gives details about system events that occur during start-up and operation and also the general state of the switch. Typical information recorded in the System Log includes all major events during start-up, system changes, unexpected events and configuration errors. The System Log reports such things as software successfully located and loaded, ports enabled or disabled, and if any SNMP traps have been sent. Use of this tool is described in “System Window”, p. 38

5Check for any relevant messages in the Errors window. Use of this tool is described in “Errors Window”, p. 39.

6Check the fault counters on the switch ports and watch for any signiﬁcant error counters.

Further Evaluation of the Problem

If you still cannot resolve the problem after following the procedures above, access the Monitoring menu within Local Management. Mon- itoring is a valuable tool for the troubleshooting process and offers extensive information on the performance and the status of the switch hardware and software, the switch ports and the traffic patterns on each port.

The general facilities available within the Monitoring menu are de- scribed in the following subsections. The use of these facilities de- pends on the problem and on any relevant information collected in the previous procedure.

	Typical Problems and Causes
