When you have ip information assigned on the vSwitch, does this automatically allocate to the host?   i.e. you assign a vkernel port group and then you delete this, does the actual linux server maintain this information?  If so, how can it be checked and removed?

we don't assign ip to vswitch, vswitch is just like physcial switch. IP are assigned to vnic's which are like uplinks to virtual network. Linux server doesn't maintain any information related to vmkernel when its added r deleted.

Great, I wanted to be sure.  So it only would maintain the initial ip address that was assigned?

I am sure that you are not refereeing to Linux servers as to service console of ESX. If Linux server is running as a VM guest on your ESX then linux server just maintains the IP address of its Virtual network interfaces as u assign and once you remove its all deleted from the configs of linux servers /etc/sysconfig/network-scripts/ifcfg-eth#
If the virtual/physical network interface configuration naming starts as ifcfg-eth0,ifcfg-eth1 etc...

Ok, thanks.  I will check it.  Also, how does the vswich allocate the observed ip ranges for an interface?  I did not assign them, and it appears they were automatically generated.  I do see one that is wrong, how do you change it?

I vswitch has nothing to do with IP ranges for an interface. If you add physical NIC's to a vswitch the vswitch will observe the IP range present on the vlan('s) which live on the physical network. This is just an observation and let you know that there is an actual working network connection available. However it does not allocate anything. It just 'sees' the subnets available on the physical attached NIC('s).
You cannot change it.
