Cisco Cisco TelePresence MX700 Manual De Mantenimiento

Upgrades to TC5/TE6 from a previous release
For existing customers upgrading to release TC5.x 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 MX series, EX series, Codec C Series, 

Profile series and Quick Set C20 running software release 

TC5.0 or later; and Cisco TelePresence SX20 Quick Set which 

is supported from release TC5.1; and the EX Series supported 

in TE6.0.

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 endpoints.
