Hi All, I have recently upgraded our 3030S from 2.7.2P6 to 4.0.1. I followed the upgrade procedure in the release documentation including parsing the backup through the python migration script. I encountered many issue when I rebooted and the applied the restoration of the config from the script. one of which is that I can no longer set the speed/duplex on an interface. Below is the config of an interface prior to the upgrade: interface ethernet 1 speed 1000 duplexity Full lldp enable rx tx lldp notification enable lldp tx-dot1-tlvs vlan link-aggregation lacp trunk 2 mode active after the upgrade the config was as below: interface ethernet 1   enable   lldp enable rx tx   lldp notification enable   lldp tx-dot1-tlvs link-aggregation vlan   trunk-group 2 lacp when I try changing the speed or duplex I get the following message: device1(config-if:ethernet:1)#speed 1000 Can not set the interface speed. device1(config-if:ethernet:1)#duplexity full Can not set the interface duplexity. I have tried stripping out all of the config from the interface and shutting the interface down. Still can’t set the speed duplex. I have also tried other interfaces on the device and it is the same result. Any ideas? ---

Hi rwilliams, This is a known problem in 4.0.1 in the non-FPGA devices. When using a 1GB copper SFP adapter, the port renders to be unusable. We have a fix for the problem and I suggest that you contact A10 support to get your problem resolved. The bug id is 190318. Genard ---

Hi Genard, the build for the upgrade was as follows: version 4.0.1, build 214 With regards to you comment, I am seeing this issue on the built 1GB Ethernet ports on the 3030S. I am not currently using any SFP modules or ports. Would the bug id 190318 also cover the normal RJ45 ports on the device? Ryan ---
