In reply to Qingao Wu.

Great explanation Quingau. Thank you so much. Sure there are further questions regarding the new SNA.
1. To make sure I got it right we are not able to provisioning VLANs, 802.1x Security.. less then 250 Series?
2.Does SNA support more then one management switch (i.e. Stack) for backup and failover / availability of SNA?
