Cisco Cisco Wireless LAN Controller Module Manuel Technique

In all WLC versions prior to Version 5.0, only one syslog server can be configured. In order to configure the
syslog server with the CLI, enter this command from the WLC CLI:

config syslog {ip−address}

In controller software release 5.0.148.0, you can enable the controller to log system events to up to three
remote syslog servers. The controller sends a copy of each syslog message as it is logged to each syslog server
configured on the controller. Because it is able to send the syslog messages to multiple servers, it ensures that
the messages are not lost due to the temporary unavailability of one syslog server.

This type of configuration helps in these situations:

One of the configured syslog servers is not available.

• 

Multiple administrator groups can monitor different message types.

• 

Large deployments can want syslog messages sent to servers across different time−zones for extended
visibility.

Note: Syslog messages are sent on UDP Port 514; additional server configuration can require a
relaxation of firewall rules.

• 

With Wireless LAN Controller Release 5.0, a new CLI has been introduced to configure syslog servers with
the CLI. The old command has been deprecated.

config logging syslog host {host_IP_address} 

In order to set the facility for outbound syslog messages to the remote host, use the config logging syslog
facility command.
