Troubleshooting

You should manually set the system clock or configure it by using Network Time Protocol (NTP).

When the switch is running, you can retrieve the OBFL data by using the show logging onboard

privileged EXEC commands. If the switch fails, contact your Cisco technical support representative to

find out how to retrieve the data.

When an OBFL-enabled switch is restarted, there is a 10-minute delay before logging of new data

OBFL is supported only on Catalyst 2960-S switches. It is not supported on Catalyst 2960 switches.

Configuring OBFL

To enable OBFL, use the hw-module module [switch-number] logging onboard [message level level]

global configuration command. On Catalyst 2960-S switches, the range for switch-number is from

1 to 4. Use the message level level parameter to specify the severity of the hardware-related messages

that the switch generates and stores in the flash memory.

To copy the OBFL data to the local network or a specific file system, use the copy logging onboard

module stack-member destination privileged EXEC command.

We recommend that you do not disable OBFL and that you do not remove the data stored in the flash

To disable OBFL, use the no hw-module module [switch-number] logging onboard [message level]

global configuration command.

To clear all the OBFL data in the flash memory except for the uptime and CLI command information,

use the clear logging onboard privileged EXEC command.

In a switch stack, you can enable OBFL on a standalone switch or on all stack members by using the

hw-module module logging onboard [message level level] global configuration command.

For more information about the commands in this section, see the command reference for this release.

Temperature—Temperature of a standalone switch or a stack member

Uptime data—Time when a standalone switch or a stack member starts, the reason the switch

restarts, and the length of time the switch has been running since it last restarted

Voltage—System voltages of a standalone switch or a stack member
