Aruba Wireless Controller Syslog Configuration

This article covers what is Aruba Wireless and how to configure syslog on Aruba Wireless controller to forward events.

Aruba Wireless is a secure, high-performance, multi-user wireless LAN supporting Wi-Fi 6. As workplaces and user expectations change, users can now maintain hybrid workplaces and IoT without compromising performance, reliability, or security.

Prerequisites

• The syslog protocol uses port 11535, therefore, ensure that 11535 is allowed between the controller and the Forwarder IP. The source IP address of syslog messages is the IP address of the interface where the packet exits the controller. Multiple syslog servers can be defined.  In this case, multiple copies of syslog messages will be sent.

• • AP-Debug — Detailed log about the AP device.
  • Network — Log about change of network, for example, when a new IAP is added to a network.
  • Security — Log about network security, for example, when a client connects using wrong password.

  • User-Debug — Detailed log about client.
  • Wireless — Log about radio.

4. Click OK.

  (Instant AP)# configure terminal

• To configure a syslog server(Forwarder IP address to be given):

  (Instant AP)(config)# syslog-server <IP-address>

• To configure syslog facility levels:

  (Instant AP)(config)# syslog-level <logging-level>[ap-debug |network |security |system |user | user-debug | wireless]

• To view syslog logging levels:

  (Instant AP)# show syslog-level

       Logging Level

   -----------------------

Facility          Level

--------          ---------

ap-debug      warn

network         warn

security          warn
