Cisco Cisco IPCC Web Option Design Guide

This section presents some QoS configuration examples for the various devices in a Unified CCE system.

The QoS setup on the Unified ICM Router and PG is necessary only if the marking will be done in the 
Unified ICM and will be trusted by the network. For details, refer to the Installation Guide for Cisco 
ICM/IPCC Enterprise & Hosted Editions, available at 

This section presents some representative QoS configuration examples. For details about campus 
network design, switch selection, and QoS configuration commands, refer to the Cisco Enterprise QoS 
Solution Reference Network Design Guide, available at 

The terms public network and visible network are used interchangeably throughout this document.

The marking value, bandwidth data, and queuing policy in the examples below are provided for 
demonstration purpose only. Under no circumstances should you copy and paste the examples without 
making corresponding changes in the real working system.

If 802.1p is an intended feature and the 802.1p tagging is enabled on the NIC for the visible network, 
the switch port into which the Unified ICM server plugs must be configured as an 802.1q trunk, as 
illustrated in the following configuration example:

switchport mode trunk 

switchport trunk encapsulation dot1q 

switchport trunk native vlan [data/native VLAN #] 

switchport voice vlan [voice VLAN #] 

switchport priority-extend trust 

spanning-tree portfast 

Assuming Unified ICM DSCP markings are trusted, the following commands enable trust on an IP 
switch port:

mls qos 

    interface mod/port 

        mls qos trust dscp
