Removing FabricPath and VNTAG Headers

If you are working with a device connected to a SPAN destination port that does not understand FabricPath
or VNTAG headers, you may want those headers stripped from the packet.
You can do this at either the global or port level. If you want to strip the headers to all SPAN destination ports
in the VDC, you can apply the global command. If you want to apply the command only to a certain port,
you can use the port-level command. If the ports are not SPAN destination ports, the command is rejected.
When you enter both the global and port-level configurations for this feature, the port-level overrides the
global configuration.
Note The port-level command overrides the global command. So you can configure the device to strip the
headers globally and then issue the no form of the port-level command to exclude the specified ports from
stripping the headers.
