How to add an additional subnet

Ok, my networking team enable trunking and all the tagging on the network side of things. I have the necessary information I need as far as VLANing and stuff but I'm not sure how to implement the changes on the vmware side.

Right now, I have 3 NICs enabled. They are as follows:

vmnic0 -> vSwitch0 running Service Console

vmnic1/vmnic2 -> vSwitch1 where our VMs are running off of.

Network right now is on the 172.18.16.x/24 subnet. I'm out of IPs and would like to introduce a new subnet. 172.18.17.x/24.

What do I need to do to allow vmnic1/2 to allow traffic for the old subnet as well as the new subnet?

1 - Do I create a new vSwitch and tag that w/ the vlan id my networking team assigned? If so, I assume I would also need to tag the vlan on vSwitch0.

2 - Will I have to reboot my ESX server to accommodate the changes?

3 - Do I have to modify anything in Lab Manager?

TIA

You will need to look into 802.1q trunking to get the extra subnet presented on the ether-channel that will be presented to your VM nic team.

I am presenting 9 different subnets to a vswitch with a 2 nic team.
