Chapter 1 Overview of the MWR 1900

Limitations and Restrictions

The MWR 1900 requires a special release of Cisco IOS software. Not all Cisco IOS software features can be used with this router as the core routing is handled by the network processor. A list of supported features is included in the “Software Features” section on page 1-2. The following features are not supported on the MWR 1900:

•Security Access Control Lists

•MPLS

•802.1Q VLANs

•Frame Relay (FR)

•MLP LFI

•ATM

•Use of additional WICs (The only supported WIC is the VWIC-2MFT-T1DIR/ VWIC-2MFT-E1DIR.)
