Using the Cisco Media Convergence Server Network Teaming Driver with Operating System Version 2000.4.2
The Cisco Media Convergence Server (MCS) Network Teaming Driver enables the functionality for the failover fault-tolerant network adapters. This driver works with Cisco Media Convergence Servers that have dual network interface cards (NICs) installed. With this functionality, the standby NIC can handle all IP traffic if the primary NIC fails.
Operating system version 2000.4.2 automatically installs the Network Teaming Driver as part of the installation process. You must perform configuration tasks, as described in this document, to set up and use the Network Teaming Driver.
Use this document with operating system version 2000.4.2 or later. For information about installing and configuring the Network Teaming Driver with earlier versions of the operating system, refer to previous versions of Using the Cisco Media Convergence Server Network Teaming Driver with Operating System, which are available at this URL:

Dissolving the Network Teaming Driver
When you dissolve the driver, you disassociate the two NICs and the virtual NIC that is used for the driver. The teaming drivers remain installed, but they no longer are configured or used.
In this case, the server will use NIC #1 only for IP telephony.
To dissolve the Network Teaming Driver, perform the following procedure:

Note
Submitting a Service Request
Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:
http://www.cisco.com/techsupport/servicerequest
For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.
To open a service request by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447For a complete list of Cisco TAC contacts, go to this URL:
http://www.cisco.com/techsupport/contacts
Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
