Hi everyone, First time dealing with Dell SW, so any recommendation is greatly appreciated. Desires features: 1) Can support OSPF. 2) IPSEC in tunnel mode 3) VRRP 4) RSTP 5) Open Flow 6) VLANS 7) At least 40 Copper based ports , atleast 4 SFP based ports for 100M/1G. Looking for the cheapest managed Dell Switch that can support the above mentioned features. Thanks
