4.3.2. Redundant LAN Interfaces (Bonding) 
INFO:
LAN Interface Bonding configuration via SoftGate/Enterprise-Gateway WBM is no
longer supported starting with V10R1.
LAN redundancy configured via Platform (firstinstall.xml) should be used instead.
For more information, see the OpenScape 4000, Installation, Configuration
and Migration document.
IMPORTANT:
Customers using MAC based Network Access Control (NAC) with STMIX/STMIY
and no LAN separation (Voice- and Management-LAN) must add both MAC addresses of the
STMIX/STMIY (eth0 and eth1) to the related NAC equipment.
