> # Allowed Source Interface Types

> The SPAN feature is available for the following interface types:

> - Physical ports such as F ports, FL ports, TE ports, E ports, and TL ports.
> - Interface sup-fc0 (traffic to and from the supervisor):
> - The Fibre Channel traffic from the supervisor module to the switch fabric through the sup-fc0 interface is called ingress traffic. It is spanned when sup-fc0 is chosen as an ingress source port.
> - The Fibre Channel traffic from the switch fabric to the supervisor module through the sup-fc0 interface is called egress traffic. It is spanned when sup-fc0 is chosen as an egress source port.
> - PortChannels
> - All ports in the PortChannel are included and spanned as sources.
> - You cannot specify individual ports in a PortChannel as SPAN sources. Previously configured SPAN-specific interface information is discarded.
> - IPS module specific Fibre Channel interfaces:
> - iSCSI interfaces
> - FCIP interfaces
