vCenter with hosts in different vlans

I guess the one has nothing to do with the other. A VLAN is just a logical separartion of a network, usually done by a switch, which handles several networks (VLANs) independend from each other. It is like you splitt the switch into two independed switches.

As a VLAN is its own logical structure, one VLAN can not see the other (the sense of a VLAN).
If you want to access one device on one VLAN by another device on another VLN, you need a router, which connects the VLAN together again and handles the traffic.

I have a L3 switch there for routing purposes.

If configured int the right way, a router can connect all the VLANs together, But have in mind, that routing has all the time two ends. A package is sent out on one route, and there have also to be a route, which rediects the packet back to the sender Make sure the routing works in both directions.

OK i know all of this already.

There is VACLS which will be preventing intervlan communication (by design).

Perhaps I should setup a management NIC for each ESX hosts and put that all on the same VLAN?

VCenter server must have access to ALL VLANs

Is your vCentet server physical or virtual?

Do you have inter VLAN routing ?

vcenter is virtual.

I do have intervlan routing via a L3 switch.

Wondering whats the cleanest way to do this.

Thanks

You could create several.VLAN portgoups on all your Hosts and tag clans on virtual machine network but vCenter Server will then need a nic per VLAN

or should i just make a ACL to allow the IP of my vcenter to each ESX host?

I have my esxi management VLans as following - Production exsi hosts in 21, dev in VLAN 31 and DMZ in 41.
Vcenter runs in production with VLAN 50. I need to manage all these 3 clusters using same vcenter.
what is the best practice to do it?
