Set-VMGuestNetworkInterface : Cannot bind parameter 'VmGuestNetworkInterface'

Hi,

I am New to VMWare

I had created VM's from template.All these newly created VM's having the same system name & IP address(static)

I have to set uniq IPaddres for these VM's .

I am executing below mentioned Commands through vSphere PowerCLI

     1.Connect-VIServer –Server <Server IPAddress> –Protocol https –User <UID> –Password <pwd>

     2.Get-VMGuestNetworkInterface -VM testVM -HostUser root -HostPassword pwd123 -GuestUser Administrator -GuestPassword pwd2345

     3.Set-VMGuestNetworkInterface -VMGuestNetworkInterface Local Area Connection -HostUser root -HostPassword pwd123 -GuestUser Administrator -GuestPassword pwd2345-Netmask 255.255.255.0 -Gateway 10.10.10.1 -ip 10.10.10.11

I am getting below mentioed error after executing the command mentioned in point 3

Set-VMGuestNetworkInterface : Cannot bind parameter 'VmGuestNetworkInterface'.
Cannot convert value "Local Area Connection" to type "VMware.VimAutomation.ViCo
re.Types.V1.VM.Guest.VMGuestNetworkInterface". Error: "Invalid cast from 'Syste
m.String' to 'VMware.VimAutomation.ViCore.Types.V1.VM.Guest.VMGuestNetworkInter
face'."

ord pwd2345 -Netmask 255.255.255.0 -Gateway 10.10.10.1 -ip 10.10.10.11

After Executing the command mentioned line 2 i am getting below mentioned output

WARNING: 2 columns do not fit into the display and were removed.

VM              NetworkAdapter       Name                      IP
--              --------------       ----                      --
testVM          Network adapter 2    Local Area Connection 2   169.254.194.55
testVM          Network adapter 1    Local Area Connection     169.254.200.201
testVM                               isatap.{E0C1C55C-D756-...
testVM                               isatap.{5BD23E53-ABB4-...

Please do let me know how to fix this issue

I tried out with below values for <VMGuestNetworkInterface>

i..Local Area Connection (with double quotes & without quotes)

ii.Local Area Connection 2 (with double quotes & without quotes)

iii.Network adapter ((with double quotes & without quotes)

Do let me know What value I need to pass for the argument "VMGuestNetworkInterface"

And let me know whether I am following correct process or not for  changing the IPaddress? Else let me know the best practice/solution to sort out this issue.

Note: I am using OS 'WIndows 2008 R2 Standard" SP1
