Q. What Cisco IOS Software feature images does the Cisco ME 3400 Series support?

A. The Cisco ME 3400 Series supports three different Cisco IOS Software feature images: METROBASE, METROACCESS, and METROIPACCESS. The METROBASE feature image includes features for converged triple-play services. The METROACCESS includes these, plus features for premium triple-play services or Layer 2 VPN services. The METROIPACCESS image contains all the preceding plus features for Layer 3 VPN services. Upgrade options are also available for future service requirements.

Q. Do I have options to select the software version?

A. The Cisco ME 3400 Series supports the Assemble To Order (ATO) fulfillment process. This enables you to select the version of software you want to be loaded on the switch. In addition, you can select the type of accessories that come with the switch.

Hope to help
