Determining the Firmware Version
To determine the version of firmware currently running on your Cisco 880VA series router, issue the following IOS command and look for the output in BOLD:
Router#show controller vdsl 0Firmware Source File Name (version)-------- ------ -------------------VDSL user config flash:vdsl.bin.32bdslfw (10)Modem FW Version: 100929_1300-4.02L.03.A2pv6C032b.d23bModem PHY Version: A2pv6C032b.d23bUpgrading 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/web/download/index.html
Choose Routers -> Branch Routers -> Cisco 800 Series Routers -> Cisco 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.

New modem commands are introduced with the release of the A2pv6C032b.d23b firmware and IOS release 15.1(2)T. These commands allow custom configurations of DSL modem settings to ensure DSL interoperability in different environments. Please consult your Service Provider on required modem settings for the particular SPs network.
Before you enable the modem settings, you must execute the service internal command in CONFIG mode. For example:
Router#conf tEnter configuration commands, one per line. End with CNTL/Z.Router(config)#service internalThe following list contains the modem settings:
