Important Notes

The following sections contain important notes about Cisco IOS Release 15.6M&T:

ADSL/VDSL Embedded Firmware and SDK Change with Cisco IOS Release15.6(3)M

The ISR800 and ISR G2 which run the IOS release 15M/T is integrated with the DSL Firmware 35J for DSL Annex(es) A/M and 35J for Annex B/J. With Cisco IOS Release 15.6(3)M, the plan is to change the embedded BRCM Firmware in IOS to 39Tfor Annex A/M and 38r1 for Annex B/J. This change will affect only the 880/890 and ISR G2+EHWIC SKUs which carry the BRCM6368 chipset. There is also a plan to upgrade the current SDK version, which is used to compile the Firmware. The SDK version for bootloader and embedded LINUX must be 4.14L.04A. If you plan to migrate to Cisco IOS Release 15.6(3)M or later releases, you must use the embedded 39T FW version or later, compiled with the newer SDK. You can continue to use the available Firmware versions if you are on Cisco IOS Release 15.6(2)T or earlier releases.

Logging into the Embedded AP and Etherswitch Modules

Starting from Cisco IOS Release 15.6(03)M03, you have to configure 'transport input all' under the 'line config' to log in to the embedded AP and Etherswitch modules.
