To link a physical NIC to a vSwitchwhich is necessary in order for the vSwitch to pass traffic onto the physical network or to receive traffic from the physical networkuse this command: esxcfg-vswitch -L ...

The topic of how to configure the load balancing policy for a vSwitch from the command line interface (CLI) seems to come up rather often, so here's the command to do that in VMware ESX 3.5 U2.

esxcfg-vswitch -L vmnic# vswitch# (where vmnic# is the chosen vmnic (pNIC) and vswitch# is the chosen vswitch) ... esxcfg-vswitch -U vmnic# vswitch# (where vmnic# is the chosen vmnic (pNIC) and vswitch# is the chosen vswitch) ...

To configure a service console network you need to create a vswitch and port group first (let's say vSwitch0 and Service Console ... Then you need to link one or more physical nics to the vswitch (let's say vmnic0 and vmnic2) ...

I created one vSwitch with two NICS and two Port Groups and then used the Overriding Policies for a Port Group policy to bind the Service Console to vmnic0 and the Virtual Machines to vmnic1. On top of that, I still have redundancy. ...

VMware ESX virtual machine networking is pretty straightforward. A virtual switch (vSwitch) is created on each host by default and is associated with one

esxcfg-vswitch --unlink=vmnic0 vSwitch0. After this vmnic0 is removed from the vswitch and you can connect again to the host with the vi client. Maybe there is a quicker solution but this worked for me. Posted by John Bons at 02:30 0 comments ...
