Chapter 60 Monitoring Network Traffic Using SPAN
Monitoring Traffic Using Fibre Channel Analyzers
Session 2 (active)
Destination is fc1/9
No session filters configured
Ingress (rx) sources are
vsans 12
fc1/6 (vsan 1-20),
Egress (tx) sources are
fc1/6 (vsan 1-20),
Once upgraded to Cisco MDS SAN-OS Release 1.1(1):
Session 2 (inactive as no active sources)
Destination is fc1/9
No session filters configured
No ingress (rx) sources
No egress (tx) sources
Note The deprecated configurations are removed from persistent memory once a switchover or a new
startup configuration is implemented.
Session 2 had a source VSAN 12 and a source interface fc1/6 with VSAN filters specified in Cisco
MDS SAN-OS Release 1.0(4). When upgraded to Cisco MDS SAN-OS Release 1.1(1) the following
changes are made:
–
The source VSAN (VSAN 12) is removed (rule 1).
–
The source interface fc1/6 had VSAN filters specified—it is also removed (rule 2).
Monitoring Traffic Using Fibre Channel Analyzers
You can use SPAN to monitor traffic on an interface without any traffic disruption. This feature is
specially useful in troubleshooting scenarios where traffic disruption changes the problem environment
and makes it difficult to reproduce the problem.
Without SPAN
You can monitor traffic using interface fc1/1 in a Cisco MDS 9000 Family switch that is connected to
another switch or host. You need to physically connect a Fibre Channel analyzer between the switch and
the storage device to analyze the traffic through interface fc1/1 as shown in
Figure 60-8.
