Pre-requirement & reference:

How to approach BMC on Advantech CIoT platforms

How to set BMC IP address

How to setup BMC IP address via BIOS

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

* IANA = Internet Assigned Number Authority 

 

Purpose:

This article will introduce how to switch Management Ethernet ports (front panel) to dedicate BMC usage or shared NIC on SKY-8101 series.

Target Audience:

All users who are using Advantech SKY-8101 series products

Use Cases:

For user who wants to physically isolate management traffic to BMC alone , we will suggest to switch MGT port to "dedicate" mode.

How to approach this?  By switch set on SW4

Let's check the difference on SKY-8101 in Operating System in below

 

Default :  Shared NIC mode,  both mgmt devices can be seen in OS Ethernet list.

Set 1-4 to ON ; 2-3 to OFF   --- > NIC1 for dedicate use , OS CANNOT detect mgmt1 port, only NIC2 is on the list. Both mgmt ports are able to access BMC through default IP 192.168.1.1/192.168.2.2  , fine to open web-ui.
