<# .Synopsis Test host networking .Description Pings addresses from each provided VMkernel port of VMHosts provided .Parameter VMHosts The VMHosts you want to ping from. Can be a single host or multiple hosts provided by the pipeline. Wildcards are supported .Parameter VMkernel The VMkernel ports to ping from .Parameter IpAddress The IP addresses to ping .Parameter Mtu The ping buffer size (Use 1472 for standard frames and 8972 for jumbo frames) .Example PS C:\>$vmhosts = "esxi*" PS C:\>$mgmt_vmks = 'vmk0' PS C:\>$mgmt_addrs = Get-VMHostNetworkAdapter -VMHost $vmhosts -Name $mgmt_vmks | select -ExpandProperty IP PS C:\>Test-VMHostNetworking -VMHosts $vmhosts -VMkernelPort $mgmt_vmks -IpAddress $mgmt_addrs Ping sweep complete.
