DiffServ Application Statistics
Dean wants to verify that only voice related protocols that he configured for DSCP value 26 are actually the
only protocols transmitting with that value. To look at which applications are sending packets using certain
DSCP values, Dean does the following:
Step 1. Select Monitor > DiffServ > Application Stats. The DiffServ Application Statistics screen is
displayed.
Step 2. Select VLAN 100-QoSsearch from the Data Source-Profile pull-down list.
Step 3. Select the DSCP value from the Aggregation pull-down list (DSCP 26). Note: This list will
contain all possible aggregations (DSCP values with labels in the profile), not just the ones with
traffic.
Dean is happy to see that the only protocols listed are the ones he expected. Had there been unexpected
protocols listed, Dean could quickly resolve the aberration to Q-Bits QoS plan.
Dean next selects a protocol to view which hosts are transmitting using this protocol with a DSCP value set
to 26. Besides clicking the protocol itself, Dean could also get the same results by selecting the radio button
next to the protocol and clicking the Details button. As expected, Dean only sees the Call Manager server
using the various voice protocols.
