Vcap-Dca Objective 2.4 – Administer Vnetwork Distributed Switch Settings

Front 1

Describe the relationship between vDS and the vSS

Back 1

Networking, page 22

vSS represents the configuration of networking on the host.

vDS represents the configuration of the network across hosts via vCenter.

Front 2

Understand the use of command line tools to configure appropriate vDS settings on an ESXi host

Back 2

Command Line Interface Solutions and Examples, page 122

List and view all vSwitches (vSS and vDS on a host)

vicfg-vswitch -l

Add an uplink to a DVPort on a DVSwitch

vicfg-vswitch --add-dvp-uplink=<vmnic>

Delete an uplink from a DVPort on a DVSwitch (must specify DVport ID)
vicfg-vswitch --del-dvp-uplink=<vmnic>

Specify a DVPort ID for the operation
vicfg-vswitch -dvp=<dvport>

Front 3

Determine use cases for Port Binding

Back 3

Networking, page 26

Two types of port binding:

Static - ports are assigned to VMs on the vDS and do not go away, even when VMs are turned off.

Ephemeral - makes the ports "on demand" for things like Linked Clones. Not a lot of use cases. "Grays out" number of ports when selected.
