CISCO-LWAPP-U3INTERFACE-MIB
AI MIB Summary
The CISCO-LWAPP-U3INTERFACE-MIB monitors the U3 interface between a Cisco Wireless LAN Controller (WLC) and a Cellular WLAN Controller (CWC) to facilitate Real-Time Traffic Steering (RTTS) for client sessions between 3GPP and WLAN networks. It tracks and reports calculated throughput metrics and rejection status to enable the CWC to make dynamic decisions on traffic steering or client admission based on network performance thresholds.
U3 Interface between WLC and CWC(Cellular WLAN Controller) is present to support Real-Time Traffic Steering(RTTS) of client between 3GPP networks and WLAN. Throughput needs to be calculated at WLC and shared with the CWC to take decision to steer the traffic to WLAN or not. It is also defined to reject client in case if throughput is not satisfactory along with periodic updation of throughput.
GLOSSARY
Access Point ( AP )
An entity that contains an 802.11 medium access control ( MAC ) and physical layer ( PHY ) interface and provides access to the distribution services via the wireless medium for associated clients.
LWAPP APs encapsulate all the 802.11 frames in LWAPP frames and sends it to the controller to which it is logically connected to.
Central Controller ( CC )
The central entity that terminates the LWAPP protocol tunnel from the LWAPP APs. Throughout this MIB, this entity also referred to as 'controller'.
Light Weight Access Point Protocol ( LWAPP )
This is a generic protocol that defines the communication between the Access Points and the controllers.
Cellular WLAN Controller ( CWC )
A decision making entity to steer traffic over LTE or WLAN.

to send throughput details of all the U3 interface
clients on a particular WLAN to the WLC. Reporting
interval range is 30 - 90 seconds.rw Unsigned32 UNITS "seconds" .1.3.6.1.4.1.9.9.852.1.1.1.1.2 |
