# DSCP tagging in the My Computer mode in product co-residency

## Scenario 1: DSCP tagging for a customer with Avaya IP Agent and Avaya one-X Agent (in the order of IP Agent and then One-X Agent)

The co-residency of Avaya IP Agent and Avaya one-X Agent, or Avaya one-X Agent and Avaya one-X Communicator is supported in the My Computer, Desktop Phone and Other Phone modes. In the My Computer mode, Differentiated Services Code Point (DSCP) tagging of packets by the Avaya Quality of Service (QoS) service has the following behavior:

Co-resident products | Install Sequence | DSCP Tagging
--- | --- | ---
Avaya IP Agent R7 SP8 | Avaya one-X Agent | Avaya one-X Communicator 5.2 SP4 | Avaya one-X Communicator 6.0 SP1 | Avaya one-X Communicator 6.1 | Avaya IP Agent | Avaya one-X Agent | Avaya one-X Communicator
X | X |  |  |  | Avaya IP Agent Avaya one-X Agent | X |  |
X | X |  |  |  | Avaya one-X Agent Avaya IP Agent |  | X |
| X | X |  |  | Any |  | X | X
| X |  | X |  | Any |  | X | X
| X |  |  | X | Any |  | X | X

A customer has Avaya IP Agent and Avaya one-X Agent on a single computer and wants to retain Avaya IP Agent on the computer until the customer is fully conversant with Avaya one-X Agent. Once the customer becomes fully familiar with Avaya one-X Agent, Avaya IP Agent can be uninstalled. Upon removing Avaya IP Agent, the system also removes the QoS service used for DSCP tagging. For the system to continue using the QoS Service for DSCP tagging on Avaya one-X Agent, you must complete the following steps:

1. To delete the QOSServm.exe file, on your computer

   1. Navigate to <drive>\windows\system32.

   2. In the system32 folder delete the QOSServm.exe file.

2. At the command prompt,

   1. Navigate to <drive>:\program files\Avaya\Avaya one-X Agent.

   2. Type the command: QOSServInst.exe –i <drive>\windows\system32

   3. Press the Enter key.

   4. Type:net start iClarityQOSService

   5. Press the Enter key.
