Smallest/cheapest FiaB hardware? 9200?

[Tony Rosolek]

Hello world, 

I'm looking for an appropriate SD-Access solution for very small sites. Like 5-15 LAN ports. Looking into Fabric in a box deployment with hosts directly connected to it. Could I use a small 9200 switch as FiaB in this scenario? Or even a 9200CX?

SD-Access ordering guide mentions 9300 as "lowest" FiaB plattform. Also the compatibility matrix is not showing 9200 as Control Plane/Border Node. 9200 switches are only listed as Edge Nodes.

Can I use 9200 switch as FiaB? If not, why not? What could be the alternative? Is it a 9300 24 port switch?

I know that there are specific limitations for 9200 and Fabric enabled Wireless. Especially with embedded WLCs. 

Thanks in advance
Tony

do u need to have (fabric) APs on hypothetical location? or do u have it connected with SDA-transit?
If no, on you place, i'd stop thinking about bringing LISP/VXLAN burden into the single box & free'ed up myself with platform selection for traditional networking.

Fabric APs at some sites yes, other sites not (yet). SDA-Transit probably yes. 

Idea is to have similar setup/configuration for all 50 sites. Having a mix of SDA and traditional networking would add additional complexity.

9300 is best option for Fabric in a box.

Please share more details/insight. Why is 9300 "the best option"?

Per the compatibility matrix C9200 does not support the Border Node role, thus cannot be a FIAB. FIAB = BN + CP + EN. C9300 is the minimum switching platform capable of performing FIAB function. Best regards, Jerome

Look at the below guide what features need for the FIAB (so Cat 9200 does not support some features) - hence 9300
