VLAN Voice ID may be set to the appropriate value.

Upgrading to TC5/TC6 from a previous release
For existing customers upgrading to release TC5/TC6 from a 

previous release, the existing values for these parameters will 

be maintained, the Startup Wizard is not displayed, and no 

change in behavior will be seen by the user. Note however that 

the values for the xConfiguration Network 1 VLAN Voice Mode 

parameter have changed. In previous releases the valid values 

for this parameter were Untagged or Tagged, with Untagged 

being the default. From release TC5.0, with the introduction of 

CDP support, the valid values for those parameters are now 

[Auto/Manual/Off]. During an upgrade, the previous values are 

automatically mapped to the new equivalent values. 

NOTE:

 Management applications will need to be updated to 

use the new values (e.g. Off instead of Untagged, Manual 

instead of Tagged, or Auto) in xConfiguration API requests.

Table 1 illustrates the relationship between the old and new 

values.

NOTE:

 The DHCP process is actually done in the background 

prior to the Startup Wizard being displayed. This means that 

during the first-time boot up, or after a factory reset, the 

endpoint will initially obtain a DHCP lease in the native VLAN. If 

VLAN Voice Mode Auto is then chosen, and CDP indicates that 

a VLAN should be used, the endpoint will release the address 

it received in the native VLAN, restart its IP stack, and re-

DHCP a new address in the auxiliary VLAN. This may result in 

temporary usage of IP addresses in the native VLAN during the 

first-time boot up.

Summary
This document has briefly introduced the history and benefits 

of the Cisco Discovery Protocol (CDP) and its behavior on the 

Cisco TelePresence video endpoints.

CDP is a powerful mechanism for automating the application 

of VLANs and Quality of Service for voice/video devices. 

Existing Cisco customers are encouraged to begin exploring 

its benefits and preparing their networks so they can begin 

leveraging VLANs, AutoQoS and VLAN-based security 

policies for their Cisco video endpoints.
