Configuring Analyzers Using SPAN

To configure Fibre Channel Analyzers using SPAN for the example in
Configure SPAN on interface fc1/1 in the ingress (rx) direction to send traffic on SD port fc2/1 using
Step 1
session 1.
Configure SPAN on interface fc1/1in the egress (tx) direction to send traffic on SD port fc2/2 using
Step 2
session 2.
Physically connect fc2/1 to port 1 on the Fibre Channel analyzer.
Step 3
Physically connect fc2/2 to port 2 on the Fibre Channel analyzer.
Step 4

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
the same SD port fc2/1.
Figure
is used to capture traffic in both ingress and egress direction. This setup is more advantageous and
cost-effective than the setup shown in
analyzer, instead of using a full, two-port analyzer.
