Release Notes for Firmware Release A2pv6C038k1
First Published: April 04, 2013
Introduction
These release notes describe enhancements and requirements for firmware release A2pv6C038k1, A2pv6C038h, and B2pvC038h. This firmware release is not pre-installed in any IOS routers or modules. For detailed information on supported hardware and platforms, see the “Hardware Supported” section. These release notes are updated as needed.
Note
The A2pv6C038k1, A2pv6C038h, and B2pvC038h firmware supports only G.vector features on VDSL2 and can be used only for G.vector type of deployments.

Determining the Firmware Version
To determine the version of firmware currently running on your router, issue the following IOS command and look for the output as shown below:
Modem PHY Version: A2pv6C038k1.d23j
Note For a Cisco EHWIC Multimode VDSL2/ADSL+ Mutlicard, use the slot/subslot/port number argument for the show controllers vdsl command.
Upgrading to a New Firmware Release
Perform the following steps to upgrade to a new firmware release:
1. Download the new firmware from Cisco.com Software Center at http://www.cisco.com/cisco/software/navigator.html.
Choose Products -> Routers -> Branch Routers -> Cisco 800 Series Routers -> Cisco 886VA/887VA Integrated Services Router -> Very High Bitrate DSL (VDSL) Firmware
2. Copy the firmware to a designated location; for example, router flash or a TFTP server.
3. Configure the router to load the new firmware from a designated location.
Note Controller VDSL 0 should not be turned off.
4. Enter the copy running-config startup-config command to save your configuration.
