Enable DiffServ Monitoring
Like other types of collections on the NAM, no DiffServ data is actually collected until the monitoring is
enabled on a data source. To enable DiffServ monitoring, Dean performs the following steps on the Catalyst
6500 Series NAM (NM-NAM follows the same steps):
Step 1. Select the Monitoring option under the DiffServ heading from the menu on the left side of the
screen (you should already be at Setup > Monitor). The DiffServ Monitor Setup screen is
displayed.
Step 2. From the Data Source pull-down menu, Dean selects VLAN 100. (VLAN 100 is the main VLAN
for the server farm. Remember, the span source is still port Gi1/2, which connects the
distribution switch to the server farm workgroup access switch.)
Step 3. From the DiffServ Profile pull-down list, select QoSsearch (the profile just created).
Step 4. Enable all types of statistics collections. Note: You can change the number of applications and
hosts the NAM collects statistics for by selecting 100, 500, or Max Possible from the associated
Max Entries pull-down list.
Step 5. Click Apply to enable the collection of traffic, application, and host statistics based on the
DSCP values for all packets on port Gi1/2, VLAN 100.
Dean is now ready to look at the traffic based on DSCP values.
