1. Administration
Default: LOCAL7
Syslog facility name - { USER, LOCAL0, LOCAL1, LOCAL2, LOCAL3, LOCAL4, LOCAL5,
LOCAL6, LOCAL7 }.
Syslog Facility is an information field associated with a syslog message. The syslog facility
is the application or operating system component that generates a log message. ROS®
maps all syslog logging information onto a single facility, which is configurable to facilitate
a remote syslog server.
Severity
Synopsis: { EMERGENCY, ALERT, CRITICAL, ERROR, WARNING, NOTICE,
INFORMATIONAL, DEBUGGING }
Default: DEBUGGING
Syslog severity level - {EMERGENCY, ALERT, CRITICAL, ERROR, WARNING, NOTICE,
INFORMATIONAL, DEBUGGING}.
The severity level is the severity of the generated message. Note that the selected severity
level is accepted as the minimum severity level for the system. For example, if the severity
level is set as "Error", then the system sends any syslog message generated by Error,
Critical, Alert and Emergency events.

1.16. Troubleshooting

Problem One
I have configured the IP address and a gateway. I am pinging the switch but it is not responding.
I am sure the switch is receiving the ping because its port LEDs are flashing and the statistics
menu shows the pings. What is going on?
Is the switch being pinged through a router? If so, the switch gateway address must be
configured. The following figure illustrates the problem.
Figure 1.30. Using A Router As A Gateway
The router is configured with the appropriate IP subnets and will forward the ping from the
workstation to the switch. When the switch responds, however, it will not know which of its
interfaces to use in order to reach the workstation and will drop the response. Programming a
gateway of 10.0.0.1 will cause the switch to forward unresolvable frames to the router.
This problem will also occur if the gateway address is not configured and the switch tries to
raise an SNMP trap to a host that is not on the local subnet.
