C9300X Bad IPv4 assignment configuration

[Jayt]

Hi

I have a stack of 4 of these. SW1 & SW2 are displaying this message.  2 days ago & for weeks before I had no errors. This appeared 2 day ago.  There have been no changes in the switches IP information, or any network changes upstream or downstream. I rebooted the stack & same error. The only things I have done is assign VLANS on ports that needed to be live.

These are DHCP & getting the correct IP information.  All 4 switches are displaying the same IP because it's a logical switch stack. SW3 & SW4 appear fine. Everything still works on SW1 & SW2.

This did happen 1 other time a few months ago & it just cleared on it's own.

Ideas?

thanks

Are there any potentially duplicate IP addresses?

Is the management VLAN configured correctly?

Is the management interface gateway correct?

Bad IPv4 assignment configuration

Yes it's all correct.  It was not touched. The same IP information is correct on all 4 switches & nothing else is assigned to the MGMT VLAN I have set up.  

All 4 switches are using the same IP address as it's a logical switch stack.  I am opening a ticket, but seeing what you guy can suggest as well.

Thanks

Actually..scratch that!  All good now.  For some reason the IP assignement changed to static on those 2 switches instead of DHCP.  It's all green now.  Have to look at change log cause I didn't do that.

Thanks
