I have added new gigabit NIC`s on all the ESXi servers and before making any modifications to the traffic flows I wanted to see that the network was up and running. So, the following script came in handy:
### Get pnics and their link speed
get-vmhost | foreach {
$_.Name
$pnics = $_.NetworkInfo.ExtensionData2.NetworkInfo.Pnic
foreach ($p in $pnics) {
$row=""
$row += $p.Device + " " + $p.LinkSpeed.SpeedMB
$row
}
}
get-vmhost | foreach {
$_.Name
$pnics = $_.NetworkInfo.ExtensionData2.NetworkInfo.Pnic
foreach ($p in $pnics) {
$row=""
$row += $p.Device + " " + $p.LinkSpeed.SpeedMB
$row
}
}
After
finishing all reconfigurations on ESXi networking - mainly
redistributing traffic flows on the newly installed NIC`s, I felt the
need to have a quick look over the deeds just done. The idea was to
check that ESXi hosts had the correct vmk interfaces and the correct IP
addresses. So, another small bit of scripting:
###Get vmk interfaces and IP addresses for all hosts
foreach ($vmh in
get-vmhost)
{
$row = ""
$row += $vmh.Name + " "
foreach ($i in $vmh.NetworkInfo.ExtensionData2.NetworkConfig.Vnic)
{
$vmk= $i.Device
$row += $vmk + " "
$vmkip = $i.Spec.Ip.IpAddress
$row += $vmkip + " "
$vmksubnet = $i.Spec.Ip.SubnetMask
$row += $vmksubnet + " "
}
$row
}
{
$row = ""
$row += $vmh.Name + " "
foreach ($i in $vmh.NetworkInfo.ExtensionData2.NetworkConfig.Vnic)
{
$vmk= $i.Device
$row += $vmk + " "
$vmkip = $i.Spec.Ip.IpAddress
$row += $vmkip + " "
$vmksubnet = $i.Spec.Ip.SubnetMask
$row += $vmksubnet + " "
}
$row
}
