Cisco Cisco IP Contact Center Release 4.6.1 설치 가이드

If Use Packet Scheduler is unchecked for Side A, it must be unchecked for Side B.

Note: Cisco recommends NOT implementing Microsoft Packet Scheduler for ICM 7.0(0). For
more information about ICM QoS, and about this recommendation in particular, refer to the
Pre-Installation Planning Guide for Cisco ICM Enterprise Edition. If you plan to use Microsoft
Packet Scheduler you must install it separately—it is not installed from ICM Setup.

Select DSCP priority markings and 802.1p priority tagging, and enter Bandwidth information,
as appropriate and allowed—if Packet Scheduler is used, Setup checks that Total usable
bandwidth (Kbps) is at least 1544 and that the Bandwidth Percent values add up to 100.

Note the following differences among the four forms:

•

With Packet Scheduler there are only two priority levels (High and Low)—the Medium
Priority traffic is marked the same as the Low Priority traffic.

•

Bandwidth settings are not enabled on Side B because that information is obtained from Side
A.

•

The Select Network Interface Card list is used only with Packet Scheduler, in which case a
Card must be selected from the display of available Cards.

•

When using Packet Scheduler, the same DSCP and 802.1p settings must be used for every
ICM instance that uses a given Network Interface Card. Record the settings you use to make
sure that this rule is followed.

•

When not using Packet Scheduler, the Side B dialog box has no fields enabled because the
information is obtained from Side A.

Click OK, which accepts the information that you entered, and returns you to the Central
Controller Network Interfaces dialog box.

For the Central Controller Network Interfaces dialog box,

How to Set the QoS Feature for the Router Visible Interfaces

In the Central Controller Visible Link QoS Settings dialog box, either check Use Packet
Scheduler, or click Cancel. (There is no Enable QoS box in the Central Controller Visible
Link QoS Settings dialog box. QoS is enabled if, and only if, it is enabled for the PG Visible
Link QoS Settings. Further, when not using Packet Scheduler, no fields are enabled because
the information is obtained from the PG Visible Link QoS Settings.)

If you have checked Use Packet Scheduler, select DSCP priority markings and 802.1p priority
tagging as appropriate and allowed. With Packet Scheduler there are only two priority levels
(High and Low)—the Medium Priority traffic is marked the same as the High Priority traffic.
