Hi. Sorry for posting twice but this is another topic.
I'm comparing the two models for my servers.

The cost of the two model is almost same,
but some posting here says that RB3011 has more feature than RB4011 which is last model.

The most used feature from the switch will be Vlan configuration including vlan trunking and dhcp.

It would be great if anyone could help me to guide me to proper model for my use case.

The only place I can see where the 3011 trumps the 4011 is you can do Vlan config in "software only " on 4011.

So the 4011 is a way better device, but will depend on what you planning to do with Vlans
