Lab Testing

Summary

Report

Key findings and conclusions:

 Cisco FlexConnect architecture allows branch offices

to continue functioning when the WAN link is down or
the controller is not reachable

 Port-based 802.1x authentication protects against

installation of rogue access points

 Fast Roam with CCKM does not require keys to be

exchanged, permits roaming even if the controller
is down

 Provides Voice dynamic over-the air Call Admission

Control (CAC) support to manage limited bandwidth,
latency issues and protect existing voice calls

 FlexConnect architecture provides authentication

flexibility — APs can perform 802.1x authentication

deployments. For comparison purposes, we also looked at competing
solutions from Motorola and Aruba; specifically Motorola WiNG v5.0
and Aruba Virtual Branch Networking 2.0.

As wireless branch deployments are expanded to larger branch
applications, several interrelated factors are of concern: continuity of
business operations at the branch when WAN connectivity to the
datacenter is lost, and deployment cost. Miercom selected several

isco engaged Miercom to perform an independent validation of
their FlexConnect architecture featuring the Flex 7500 WLAN
controller, with a focus on resiliency as it applies to branch office
