LS1043A Ethernet Port interconnection issue

[desgin]

Hello Experts,
I am facing Ethernet port issue with the NXP board LS1043A-RDB
Setup:

• All 7 ethernet ports of NXP boards are connected with 7 different Linux system ethernet port through LAN cable

Issue facing:

• Only 1 ethernet port of NXP board is connected to Linux system 1 but still able to ping other 6 ethernet ports of NXP device through static IPs

So need your kindly support to know the behavior of each ethernet port to resolve this issue which is not available in the datasheet.
Requirement:

• Need to connect all 7 ports independently to work with independent system.
• Able to ping only 1 ethernet port of NXP device from Linux system 1
• Speed should be at least 1 Gbps

Attachments:

1. Image 1: Architecture of NXP board and Linux system 1
2. Image 2: NXP device static IPs - through ifconfig
3. Image 3: Static IP of Linux system 1
4. Image 4: Ping 1st ethernet port - static Ips of NXP board from Linux system 1 - Expected response
5. Image 5: Ping 2.. ..7 ethernet port - static Ips of NXP board from Linux system 1 - Unexpected response

Thanks in advance!
