Q. Explain Port Groups in VMWare?

In vSphere 4.x we have Three types of port groups:

1. Virtual Machine.

2. VMKernal Port Group.

3. Service Console Port Group.

In vSphere 5.x we have two types of port groups:-

  1. Virtual Machine-> for passing VM traffic.
  2. VMKernal Port Group-> The VMKernal TCP/IP stack handles traffic for the following ESXi Servers: vSphere, VMotion, Fault Tolerance, iSCSI, NFS and host management.

In the VMotion port group label the N/W name carefully as it is case sensitive. If you fail to label the name of the N/W correctly the whole VMotion N/W fails.
