SPAN Sources

SPAN sources refer to the interfaces from which traffic can be monitored. You can also specify VSAN
as a SPAN source, in which case, all supported interfaces in the specified VSAN are included as SPAN
sources. You can choose the SPAN traffic in the ingress direction, the egress direction, or both directions
for any source interface:

IPS Source Ports

SPAN capabilities are available on the IP Storage Services (IPS) module. The SPAN feature is only
implemented on the FCIP and iSCSI virtual Fibre Channel port interfaces, not the physical Gigabit
Ethernet ports. You can configure SPAN for ingress traffic, egress traffic, or traffic in both directions for
all eight iSCSI and 24 FCIP interfaces that are available in the IPS module.
You can configure SPAN for Ethernet traffic using Cisco switches or routers connected to the Cisco MDS
Note
9000 Family IPS modules.
