When using an extended ACL with the access-group command to define traffic using the
class policy-map configuration command, the Cisco MWR 1941-DC router crashes to ROMmon.
This condition happens because extended ACLs are currently not supported.

This condition happens because extended ACLs are currently not supported.
Workaround: The access-group command is not part of the IP-RAN configuration. However, if
using the command, use only with standard ACLs.

When traffic shaping is applied to an MLP output interface, the shaped output rate might be slightly
higher than that defined. This condition occurs because the data rate to that interface is greater than
the shaping rate.

During periods of heavy multicast traffic (approximately 5000 pps), some multicast packets are
dropped at the MWR 1941-DC MLP interface.

100 pps or more causes a periodic “out-of-sequence” condition in the MWR 1941-DC IOS
decompression.
