access-list 101 permit tcp host Public_NonHigh_IP any

access-list 101 permit tcp any host Public_NonHigh_IP

Second, classify the traffic using a class map:

class-map match-all ICM_Public_High

    match access-group 100

class-map match-all ICM_Public_Low

    match access-group 101

Third, define the marking policy using a policy map:

policy-map ICM_Public_Marking

    class ICM_Public_High

        set ip dscp af31

    class ICM_Public_Low

        set ip dscp af11

Finally, apply the marking policy to the incoming interface:

interface mod/port 

    service-policy input ICM_Public_Marking

Once the QoS-enabled processes are up and running, the Microsoft Windows Performance Monitor 
(PerfMon) can be used to track the performance counters associated with the underlying links. For 
details on using PerfMon for this purpose, refer to the ICM Administration Guide for Cisco ICM 
Enterprise Edition, available at 

This section discusses bandwidth provisioning consideration for the Unified CCE system.

This section briefly describes bandwidth sizing for the public (visible) and private networks.

Special tools are available to help calculate the bandwidth needed for the following public network links:

A tool is accessible to Cisco partners and Cisco employees for computing the bandwidth needed between 
the ICM Central Controller and Unified CM. This tool is called the ACD/CallManager Peripheral 
Gateway to ICM Central Controller Bandwidth Calculator, and it is available (with proper login 
authentication) through the Cisco Steps to Success Portal at
