Table 3 lists the supported Cisco 886VA and 896VA Series Multimode VDSL2/ADSL2/2+ with WLAN
platforms and memory requirements while using firmware release B2pvC038r1.
Determining the Firmware Version
To determine the version of firmware currently running on your Cisco C886, C887, C896 and C897 series router, issue the following IOS command and look for the firmware version entries shown at the end of this example:
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 886, 887, 896 or 897 VA Integrated Services Router -> Very High Bitrate DSL (VDSL) Firmware > VA_A_38q_B_38r1_24j.bin
2. Copy the VA_A_38q_B_38r1_24j.bin 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.
