1. Limitations of the release BRS 09.4.04
==============================================

If the file system is formatted with HiOS 08.0.00 software release or newer, a 
	downgrade to release 07.4.xx is not working.

IGMP Snooping: Unknown multicast traffic is flooded by default. 
     You have the option of changing the setting for this traffic in the 
     device management to �Discard�. The setting �Send to Query Ports�
     is not supported.

IP version 4: Packets containing short ipv4 headers or short tcp headers and
     packets that are too short for their ip headers are dropped by the switch. 

MACsec: Hardware of BRS MACsec variants is MACsec ready. Software support will
     follow in a future release.
