IPS Source Ports
Effective SAN-OS Release 1.3(x) Switched Port Analyzer (SPAN) capabilities are also 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 SPAN 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
9000 Family IPS modules.
CSM Source Ports
Effective SAN-OS Release 1.3(x) Switched Port Analyzer (SPAN) capabilities are also available on the
Caching Services Module (CSM).
Refer to the Cisco MDS 9000 Family SAN Volume Controller Configuration Guide for further
information.
Allowed Source Interface Types
The SPAN feature is available for the following interface types:
•
Physical ports
–
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.
