Diagnostic Tools

Ensure that your Syslog server(s) will accept Debug messages. All Syslog messages the switch generates carry the configured facility. All Syslog messages resulting from debug operation carry a “debug” severity. If you configure the switch to transmit debug messages to a SyslogD server, ensure that the server’s Syslog application is configured to accept the “debug” severity level. (The default configuration for some Syslog applications ignores the “debug” severity level.)

A reboot temporarily suspends Syslog logging. After a reboot, the switch suspends configured Syslog logging for 30 seconds.

Port Auto-Negotiation

When a link LED does not light (indicating loss of link between two devices), the most common reason is a failure of port auto-negotiation between the connecting ports. If a link LED fails to light when you connect the switch to a port on another device, do the following:

1.Ensure that the switch port and the port on the attached end-node are both set to Auto mode.
