SPAN Traffic To/From Server Farm

To use the Switched Port Analyzer (SPAN) on traffic to and from the server farm (port Gi1/2 on distribution

switch), perform the following:

Step 1. Click Setup > Data Sources > SPAN. The Active SPAN Sessions dialog is displayed listing the

current SPAN session if any.

Step 2. Click the Create button. The Create Span Sessions data screen is displayed.

Step 3. Select Switch Port as the SPAN Type.

Step 4. From the Switch Module pull-down list, select Module 1.

Step 5. Select Both as the SPAN Traffic Direction.

Step 7. Highlight port 1/2 from the Available Sources list and click Add. Port 1/2 moves into the

Selected Sources list.

Step 8. Click Submit to make this SPAN session active.

All traffic either received or transmitted by port 1/2 is now being mirrored (copied) to the NAM. However,

before any statistics are actually collected, Dean must enable collections on the Traffic Analyzer for the types

of monitoring that he wants to perform.

Note: Dean is using a Cisco Catalyst 6500 Series NAM-1 with a single data port known as port slot/3. If you

are using a NAM-2, an additional step to creating the SPAN session would be to select the data port. On the

NAM-2, the data ports are known as slot/7 and slot/8.

Note: If all data ports are currently configured for SPAN or VACL, then you must first delete the session

before creating a new one. If the session is not deleted, you will be ask if you wish to replace the existing

session.
