CH A P T E R 8 Console Port Use and Troubleshooting

Start-up Problems

I’ve forgotten my password

Explanation: You are prompted for a password on the Login screen.

Action: Enter Maintenance Mode, and type: run defparm.

Consequence: This resets the configuration to the default values so you can assign a new password.

When I make changes to the switch’s configuration, they take effect but as soon as the switch is powered off and on again the changes are lost

Explanation: When you change the switch’s configuration, you are changing the current active configuration that is running in RAM. However, every time the switch starts up it loads the configuration that is stored in its flash memory. Therefore, if you make a change to the configuration and want to keep it, you need to save the new configuration to the switch’s flash memory.

Action: Save the configuration changes to flash memory. To check the status of the configuration, select Configura- tion>Software.

Performance Problems

One or more workstations cannot communicate with a server or other device through the switch

Explanation: This symptom might be noticed on one or more seg- ments connected to the switch, and could be caused by cable faults, inappropriate configuration or faulty installation.

Action: Check all connections and verify your configuration. Check any error counters for the ports.

I have poor performance and high numbers of second port drops

Explanation: There may be a loop in the network and Spanning Tree is not enabled.

Action: Avoid loops, or alternatively, either enable STP on all the ports (using Device Setup) or specific ports (using Port Setup).
