■
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.
