Change Default ports on new vSwitch

Hi,

Does anyone know if it's possible to change the default ammount of ports when you create a vSwitch, default is set to 120

Many thanks

We auto deploy new servers\switches\port groups etc, and we have hit the hard limit on our server 4088 ports per esx host, yes i know i can manualy change the ammount of ports per switch but the whole process is automated. So if we can set the system to only assign 32 ports per vSwitch it would be a lot easier.

The other alternative is when we create the switch's (with the API) we set it there, if thats possible.

Cheers anyway

The PowerCLI CMDLET "Set-VirtualSwitch" can set it..

http://www.vmware.com/support/developer/PowerCLI/PowerCLI41/html/Set-VirtualSwitch.html

.. so can the ESX command "vmware-vim-cmd" and ESXi using the vim-cmd command.

But Im not sure if you can add the vSwitch and set the number of ports in a one- liner.. I believe the vSwitch needs to already exists before setting the number of ports..

hi Rubeck,

i know how to change the number of ports, but i was trying to find out if it's possible to change the default from 120 to a smaller number, so when a vSwitch is created it will have less ports assigned to it.

But thanks anyway

Hi Ben,

Thanks for your reply, but unfortunatley all that does is set the number of ports on vSwitch1 to 256, it doesn't change the "Defaults".

I'm looking for a way to set the default property, so when you add a new switch, it will creat it with the default ammount of ports i specify.

Cheers

Piet

I believe that value is hardcoded.
