About the Service Port
Service Port
The physical Service port on the Cisco Wireless LAN Controller is a 10/100BASE-T Ethernet port
dedicated to Operating System device service, and was formerly known as the Management port. The

. This allows the operator to manage the Cisco Wireless LAN Controller
directly or through a dedicated Operating System service network, such as 10.1.2.x, which can ensure
Operating System device service access during network downtime.
Cisco WLAN Solution created the Service port to remove the Cisco Wireless LAN Controller device
service from the network data stream to improve security and to provide a more secure service
connection.
Note that you cannot assign a Gateway to the Service port, so the port is not routable. However, you
can set up dedicated routes to network management devices.
Also note that the Service Port is not auto-sensing: you must use the correct straight-through or
crossover Ethernet cable to communicate with the Service Port.
