Multi NIC VM Networking

[ChrisI88]

Is there a beast practices guide somewhere on vm networking?

Having an issue with VM's with multiple NICs losing their network connectivity for a short time after a reboot.

Appears to be a ARP table conflict or something related.  Using a Distributed switch with 2 physical LAN connections/per host configured as a MLT.

Thanks

Hi ,

You may use below option if you need  redundancy also best practice is separate these 3 networks

Example

Management Network  #   vmnic0 , vmnic5

vMotion Network           # vmnic1 , vmnic3

VMNetwork                    #vmnic2 , vmnic4

vmnic 0-3 can be on board physical connection

vmnic 4-5 can be external n/w card

And Connectivity should go to Two separate Physical Switch

The servers are setup as software based load balancers - hence the reason for the different IP's for different applications.  Some SSL - others not.

So having multiple ip's on multiple nics is required.  We can try multiple IP's on one nic, but I would have thought that separate NIC's with unique MACs would work better..

am not sure assigning multiple ip on vmkernal network will work properly ,  you can try

Have you checked that there isn't a conflict between multiple default gateways in your guest OS?
