A. ARM II is an enhanced ARM. It has similar software architecture to that of the original ARM. There are no configuration changes from the original ARM. There is no LAN Emulation (LANE) support on ARM II. The minimum software image required is Cisco IOS Software Release 12.1(5)EY. This table gives you a clear comparison between ARM I and ARM II features and functionalities. For more information on ARM II, refer to Catalyst 8540 Multiservice Switch Router ATM Router Module II.
