1. Limitations of the release BRS 08.7.04
==============================================

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. 

PTP: Depending on the device, PTP functionality is available only on the first
     8 to 12 ports. Full support is planned for a future release.
