# =====================================================================

# Propósito:   	Permite habilitar/desabilitar o Jumbo Frame 

#				automáticamente

# Pré-Reqs:   	1)  Interface de rede deve ter IP estático.

#             	2)  Para habilitar em um Switch Virtual do Hyper-V 

#             	não crie o Virtual switch antes de executar este script

# =====================================================================

# Exemplos:  .\Configura-jumboframe.ps1 <Modo> <IP>

#            .\Configura-jumboframe.ps1 habilita 10.0.0.1

#            .\Configura-jumboframe.ps1 disabilita 10.0.0.1

#            .\Configura-jumboframe.ps1 verifica 10.0.0.1

# =====================================================================

# v1.0 > v1.1 - 29 de Março de 2010

# 1) $FindAdapterProperties agora só verifica as chaves do registry 

# que sejam precedidos de zero

# 2) Adicionado cores no Write-Hosts
