Mobility Configuration and Verification - Legacy CUWN (5500/WiSM2) and Converged Access (3850) also called New Mobility.

 

 

Introduction

Mobility Configuration and Verification between legacy CUWN(5500/WiSM2) and Converged Access(3850) also called New Mobility.

CUWN - 5500/WiSM2 as MC and Converged Access/NGWC - 3850 as MA Mobility configuration also called New Mobility.

 

3850 Licensing

For Wireless Mobility Services to work make sure to enable appropriate license.

 

Cisco Catalyst 3850 Series Switches Data Sheet

No additional license on top of IP Base is required to operate in the mobility agent mode.

 

Cisco Catalyst 3850 Switch Deployment Guide

AP-Count license is available only with IP Base and IP Services licenses. A Cisco Catalyst 3850 Switch stack can support a maximum of 50 access points. An AP-Count license is required only if a Cisco Catalyst 3850 Switch is configured as both a mobility controller and a mobility agent. An AP-Count license is not needed if the Cisco Catalyst 3850 Switch is configured only as an mobility agent, which is the default configuration.

 

Setup

New Mobility setup between 5500/WiSM2(MC) and 3850(MA)

WLC - 5500 -  7.3.112.0 (or) 7.5.102.0 and above. Other WLC codes does not support this New Mobility.

ngwc - 3850 - 3.2.2


3850---4500(L2)---(L3)6500(L2)---5500

 

Configuring 5500 as MC and Mobility configuration

Management IP of 5500 - 10.200.200.65

Mobility config>> Enable New Mobility & Mobility Controller public ip address - Configure Management ip of 5500.
Switch Peer Group>> Created group name - EdisonSPG
Switch Peer Group member>> For Switch Peer Group "EdisonSPG" set ip of MA/3850 - 10.234.222.240

-Once Switch Peer Group is established, 3850 Need no AP license, if 5500 acting as MC already got enough license to share with 3850.

-Since 5500 is MC and 3850 is MA, 3850 absorbs the AP capwap tunnel i.e.., AP capwap tunnel terminates at 3850, only if AP's are directly connected to it. 3850 can also be used as L2 switch and have the AP terminate at 5500 by not pointing it to 5500.

-Let the AP join 3850 and confirm its using license from 5500/WiSM2 WLC.
