Monitoring Traffic Using Fibre Channel Analyzers
Figure 30-6 Fibre Channel Analyzer Using SPAN
Configuring Analyzers Using SPAN
To configure Fibre Channel Analyzers using SPAN for the example in Figure 30-6 , follow these steps:
Step 1
Configure SPAN on interface fc1/1 in the ingress (rx) direction to send traffic on SD port fc2/1 using
session 1.
Step 2
Configure SPAN on interface fc1/1in the egress (tx) direction to send traffic on SD port fc2/2 using
session 2.
Step 3
Physically connect fc2/1 to port 1 on the Fibre Channel analyzer.
Step 4 Physically connect fc2/2 to port 2 on the Fibre Channel analyzer.
Using a Single SD Port to Monitor Traffic
You do not need to use two SD ports to monitor bidirectional traffic on any interface as shown in
Figure 30-6 . You can use one SD port and one FC analyzer port by monitoring traffic on the interface at
the same SD port fc2/1.
Figure 30-7 shows a SPAN setup where one session with destination port fc2/1 and source interface fc1/1
is used to capture traffic in both ingress and egress direction. This setup is more advantageous and
cost-effective than the setup shown in
Figure 30-6 because it uses one SD port and one port on the
analyzer, instead of using a full, two-port analyzer.
