Configuring Log Outputs
As explained in “Event Log Overview” on page 258, there are two
methods for viewing the events generated by the switch. One approach is
to display one of the switch’s event logs. The drawback to this method is
that you must establish a management session with the switch before you
can view the logs and you can view the log of only one switch at a time.
The other way to view events is to configure the switch to send its event
messages to a syslog server. A syslog server can store the events of
many network devices simultaneously. Therefore, network management is
easier because you can go to one location to see all the events.
Configuring the switch to send its events to a syslog server involves
creating a log output definition. The log output contains the IP address of
the syslog server along with other information such as what types of
messages you want the switch to send.
Observe the following guidelines when you use this feature:
ˆ You can define up to 19 log output definitions.
ˆ The event log on the switch must be enabled in order for the switch to
send events to a syslog server. For instructions, refer to “Enabling or
Disabling the Event Logs” on page 260.
ˆ The switch must have an IP address and subnet mask. This rule
applies to slave switches, which typically do not have an IP address,
as well as to master switches. If you want a slave switch to send its
events to a syslog server, you must assign it an IP address and a
subnet mask.
ˆ The syslog server must communicate with the switch through the
switch’s management VLAN. The AT-S63 management software uses
the management VLAN to watch for and transmit management
packets. The default management VLAN is Default_VLAN. For further
information, refer to “Specifying a Management VLAN” on page 631.
