Configuring Log Outputs
As explained in “Event Log Overview” on page 252, 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, making it easier for you to view the
event messages because they are all stored in one location.
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 using this feature:
ˆ You can define up to 19 log output definitions.
ˆ The event log feature 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 253.
ˆ The local subnet on the switch where the syslog server is a member
must have a routing interface. The switch uses the IP address of the
routing interface as its source address when communicating with the
server. For background information on routing interfaces, refer to the
latest version of the AT-S63 Management Software Command Line
Interface User’s Guide. To configure routing interfaces using the
menus interface, refer to Chapter 29, “Internet Protocol Version 4
Routing Interfaces” on page 695 in this guide.
Note
Prior to version 2.0.0 of the AT-S63 management software, a syslog
server had to be a member of the switch’s management VLAN. This
restriction no longer applies. The server can be located on any local
subnet of the switch, provided the subnet has a routing interface.
