Hi,
ESXi has the ability to respond to CDP requests.
Check if CDP is enabled on a vSwitch
PS D:\> $vSwitch=Get-VirtualSwitch -Name vSwitch0 -VMHost myESXiHost.myDomain.org PS D:\> $vSwitch.ExtensionData.Spec.Bridge.LinkDiscoveryProtocolConfig Protocol Operation -------- --------- cdp listen
Possible values: down (disable CDP), listen (only respond to client requests), advertise (send frequently advertisments), or both (listen and advertise)
Disable CDP
PS D:\> $oESXCli=Get-EsxCli -VMHost myESXiHost.myDomain.org -V2 PS D:\> $oESXCli.network.vswitch.standard.set.Invoke(@{"vswitchname"="vSwitch1";"cdpstatus"="down"})
To enable both, listing and advertising
PS D:\> $oESXCli.network.vswitch.standard.set.Invoke(@{"vswitchname"="vSwitch1";"cdpstatus"="both"})
ENable both via esxcli.
esxcfg-vswitch -b vSwitch1 esxcli network vswitch standard set -v vSwitch1 -c both
Get CDP information in a Windows VM
