Hi everyone,

I have a 1756-EN2T/D and 1756-EN2TR/C with firmware v10.010.

From the release note, there is an anomaly:
Ethernet module sends incorrect ARP at switchover (00194847)

Corrected Anomaly with Firmware Revision 11.001

Known Anomaly First Identified as of Firmware Revision 10.006, Catalog Number:

1756-EN2T/D
1756-EN2TK/D

Known Anomaly First Identified as of Firmware Revision 10.007, Catalog Number:

1756-EN2TR/C
1756-EN2TRK/C
1756-EN2TRXT/C
1756-EN2TXT/D
1756-EN3TR/B
1756-EN3TRK/B

Known Anomaly First Identified as of Firmware Revision 10.009, Catalog Number:

1756-EN2F/C
1756-EN2FK/C

Known Anomaly First Identified as of Firmware Revision 10.020, Catalog Number:

1756-EN2TP/A
1756-EN2TPK/A
1756-EN2TPXT/A

Ethernet module sends Address Resolution Protocol (ARP) to gateway address with source IP 0.0.0.0 at ControlLogix Redundancy switchover.


For some reasons, I cannot upgrade the firmware to v11.001.
Can anyone tell me what will be happen if the Ethernet module sends Address Resolution Protocol (ARP) to gateway address with source IP 0.0.0.0?

Thank you in advance.

Switchover is only part of Redundancy System and FW 11 is not qualified to run v11 yet.
I recommend you to refer to the latest redundancy bundle.
 
Hi Contr Conn,

Thank you for your reply.
I apologize if I make you confused.
The redundant bundle I am using is v20.058kit2, which requests firmware of 1756-EN2T/D and 1756-EN2TR/C to be 10.010.
As the anomaly is fixed in 11.001, I cannot upgrade the firmware of EN2T & EN2TR to 11.001 unless I use another bundle.
But that will cause a lot non-technical issues.

Regards
