using different vlans on a UCS two different ports?

[baselzind]

i have a ucs server that is connected to my network through a single vlan access port instead of a trunk , i need to install another cucm on another vlan for testing purposes but it will have the same ip address as my current running cucm , the problem is i cant seem to be able to dedicate vmnic 1 "the second port" to the cucm test vm and it looks like virtual machines connected through both ports as a form of load balancing , im afraid even if i assign different vlan to the cucm test machine it will go through the same port whcih my live cucm is going through with the same ip address and cause issues? is there a way to let my test cucm use only vmnic1 so it will be isolated from my live cucm?

Greetings.

If you want to keep your two guestVMs network traffic separate on the physical uplinks, than you will need to create a 2nd vswitch, associate the 2nd physical NIC with that vswitch, and create a virtual port group that the test guestvm networking uses.

You can still use access port configs on the upstream switch port.

I personally prefer configuring trunk mode on the uplinks, and configuring the port-group tagging, VMK mgmt tagging, up front.  That way, you are already configured for additional guestVMs, vlans if you need to add them in the future.

Thanks,

please can you tell me how to create a second vswitch and associate a 2nd NIC to it?

https://pubs.vmware.com/vsphere-60/index.jsp#com.vmware.vsphere.networking.doc/GUID-DAF824CD-104D-4ED7-8BA3-D769DF688CEB.html is the high level on creating a vswitch.

You will have to remove the 2nd NIC (or which ever nic you want to assign to new vswitch) from the 1st vswitch, before you can assign the NIC to newly created vswitch.

the steps over vsphere 5 is somewhat different , anyway when i create a new vswitch it asks for a ip address and vlan id?

what is the ip address for? the vsphere client it self?

and why it is asking for a vlan id? i thought it should function as a trunk allowing all vlan?
