Just look at this: Isn’t this beautiful? This is the rack that I’m going to use for demos:
1×3560
2×3550 (soon to be replaced by 3560v2 or 3560e)
2651xm + NM-32A (access server)
ASA 5520 (for vpn users)
1×2801
1×1921
5×1841
1x SRX210 (in case I want to draw a comparison with Junos)
In each rack there will be a small Edimax wifi router so that each group can connect to a separate SSID on a separate wifi band.
Big thanks to Kaziu!!! (”tak to by człowiek się w niedzielę obijał i chodził z kąta w kąt”)
