* Advantech’s IANA Enterprise Number used for OEM commands is 002839h

* IANA = Internet Assigned Number Authority 

Purpose:

Delivering a notification to users who are using both MGMT ports in SAME Network Domain on Advantech SKY-8101 series

Target Audience:

All users who are using Advantech SKY-8101 series

Use Cases:

On the SKY-8101 platform, dual shared NICs (two Intel i210 Ethernet controllers) are shared 
to the BMC through side-band interface called NC-SI (see the figure below).  Every time the BMC starts up, it scans the LINK condition of both management ports  (MGMT1 and MGMT2, see Figure 3).
If both ports are linked-up and with proper IP sets, users can reach BMC via IOL in different networking domain. Here the " different networking domain " is highlighted is not because the network handling in BMC but the Management Redundancy recommendations.
