Hello,

Looks liek bug for me and cisco had fixed the version you mentioned as per the document, suggest to contact TAC, if any service outage.

Hi,

I have been receiving the same errors. Did you find a solution to this?

Thanks,

Do you have smartnet contract to raise an TAC case ?

[dm2020]

I do and I will raise a case but wanted to check if the original poster managed to resolve this issue or if its cosmetic and not actually service impacting.

We are running IOS-XE 16.9.3s which is Cisco's recommended release for SD-Access (specially built code version I believe) which is working well except for this error so hoping there is no need to upgrade.

[OaklandCounty_Mike]

No we have not found a reason for this but it also has not impacted our production environment for us. Other searches have proven that this might be a bug related to DHCP snooping. Even though we have access to open a TAC case we chose not to.

We are also running Cisco’s preferred software version on our core, distribution and edge switches.

Great, thanks for the reply. Much appreciated
