I have a ESXI host placed in let say VLAN 30 with it’s management nic connected physically to access port of L3 switch. The VM (Server 2012) hosted by the ESXI has been assigned an IP by the mikrotik router DHCP. The VM can access the internet and talk to the devices in VLAN 30. The issue is the same VM (Sever 2012) can not be accessed from other VLANs along with the client web GUI of vSphere.

Hello ED,

Your videos are really informative. I have a humble request: Can you create a video about MTU, types of MTU, and their uses?

Wonderful article!

You’ve mentioned that terminating VLANs via sub-interfaces on a router could result in increased network throughput and network congestion on that port. That could be solved by creating a bonded interface on both ends (switch and router) of the trunk port.

I don’t come from a Cisco world but I suppose it’s possible to create trunk links over bonded interfaces on Cisco devices.

Would you ever consider creating a page like this for a 3 tier Distributed Core switch network? Thanks so much for your lessons.
