Cisco IOS Software Release and Cisco IOS Software Feature Set License Requirements
Refer to Table 1 for platform support. The Cisco MFT VWIC2 cards are first supported in Cisco IOS Software Release 12.3(14)T and will be first available in the 12.4(1) mainline release. Data applications require at a minimum the IP Base feature set license and voice applications require at a minimum the IP Voice feature set license.
