System information

Introduction software version TC6

This release note describes the features and capabilities included in the Cisco TelePresence System

C/MX/EX/SX/Profile series codec software version TC6.

Important notes and warnings relevant for this software version:

Cisco TMS

If using Cisco TMS to manage EX series endpoints, Cisco TMS 13.2.2 or later is highly recommended

with TC6 or later. Cisco TMS 13.2.1 is unable to upgrade EX series endpoints to TC6. Due to a

change in endpoint software, Cisco TMS 13.2.1 could only upgrade EX series endpoints to TE6.

DHCP option 150 – RequestTFTPServerAddress default configuration changed

In TC6.1 a new configuration was introduced to allow an endpoint not using CDP (VLAN=auto) to

discover the DHCP option 150 to automatically detect the IP address of a CUCM. xConfiguration

Network 1 DHCP RequestTFTPServerAddress: On would request option 150 no matter if CDP was

used or not. In TC6.2 this configuration is enabled by default. This allows an un-configured system to

automatically discover a CUCM in the network and automatically register with it without intervention on

the system itself. Upgrading from TC6.1.x to TC6.2, a script will determine if the configuration should

be preserved or not:

• If VLAN is set to off, RequestTFTPServerAddress will be kept disabled.

• If VLAN is set to auto, RequestTFTPServerAddress will be enabled after the upgrade.

Active Control and ICE

With the new features Active Control and ICE, interworking and trunking scenarios may break. Please

see the details in the feature description or see the Administrator Guide if you wish to enable these

features.
