VCDX Enterprise Admin Notes: Objective 2.1- Skills and Abilities

by Harley Stagner on January 9, 2010

This VCDX exam note will wrap up objective 2.1 with the skills and abilities section. So, let’s jump right in.

Configure Service Console Network Using CLI

To configure a service console network you need to create a vswitch and port group first (let’s say vSwitch0 and “Service Console”)

  • esxcfg-vswitch -a vSwitch0
  • esxcfg-vswitch -A "Service Console" vSwitch0

Then you need to link one or more physical nics to the vswitch (let’s say vmnic0 and vmnic2)

  • esxcfg-vswitch -L vmnic0 vSwitch0
  • esxcfg-vswitch -L vmnic2 vSwitch0

Finally, you need to create the vswif interface on the vSwitch and attach it to the “Service Console” portgroup. (let’s say the IP is

  • esxcfg-vswif -a -i -n -p "Service Console"

Configure VLANs

To add a VLAN to a portgroup you must create the portgroup, then you must assign a VLAN ID to the portgroup (let’s say “VMNet1″ for the portgroup, vSwitch1 for the virtual switch and 100 for the VLAN ID.

  • esxcfg-vswitch -A "VMNet1" vSwitch1
  • esxcfg-vswitch -v 100 -p "VMNet1"

Configure TSO and Jumbo Frames has already been covered.

Enable Cisco Discovery Protocol

Use the -B or --set-cdp option (let’s say the virtual switch is vSwitch0)

  • esxcfg-vswitch -B down|listen|advertise|both vSwitch0

You will choose one of the four: down, listen, advertise, or both.
