How to Troubleshoot
• You have physical access to the switch.
• At least one switch port is enabled and is not connected to a device.
To delete the switch password and set a new one, follow these steps:
Step 1 Press the Express Setup button until the SETUP LED blinks green and the LED of an available switch
downlink port blinks green.
If no switch downlink port is available for your PC or laptop connection, disconnect a device from one
of the switch downlink ports. Press the Express Setup button again until the SETUP LED and the port
LED blink green.
Step 2 Connect your PC or laptop to the port with the blinking g reen LED.
The SETUP LED and the switch downlink port LED stop blinking and stay solid green.
Step 3 Press and hold the Express Setup button. Notice that the SETUP LED starts blinking green again.
Continue holding the button until the SETUP LED turns solid green (approximately 5 seconds). Release
the Express Setup button immediately.
This procedure deletes the password without affecting any other configurat ion settings. You can now
access the switch without a password through the console port or by us ing Device Manager.
Step 4 Enter a new password through the device manager by using the Express Setup window or through the
command line interface by using the enable secret global configuration command.
Recovering from Lost Cluster Member Connectivity
Some configurations can prevent the command switch from maintaining contact with member switches.
If you are unable to maintain management contact with a member, and the member switch is forwarding
packets normally, check for these conflicts:
• A member switch (Catalyst 3750, Catalyst 3560, Catalyst 3550, Catalyst 3500 XL, Catalyst 2970,
Catalyst 2960, Catalyst 2950, Catalyst 2900 XL, Catalyst 2820, and Catalyst 1900 switch) cannot
connect to the command switch through a port that is defined as a network port.
• Catalyst 3500 XL, Catalyst 2900 XL, Catalyst 2820, and Catalyst 1900 member switches must
connect to the command switch through a port that belongs to the same management VLAN.
• A member switch (Catalyst 3750, Catalyst 3560, Catalyst 3550, Catalyst 2970, Catalyst 2960,
Catalyst 2950, Catalyst 3500 XL, Catalyst 2900 XL, Catalyst 2820, and Catalyst 1900 switch)
connected to the command switch through a secured port c an lose connectivity if the port is disabled
because of a security violation.
Executing Ping
If you attempt to ping a host in a different IP subnetwork, you must define a static route to the network
or have IP routing configured to route between those subnets. For more information, see Chapter 41,
“Configuring Static IP Unicast Routing.”
IP routing is disabled by default on all switches. If you need to enable or configure IP routing, see
Chapter 41, “Configuring Static IP Unicast Routing.”
