Carl,

Configure the following on your ASA:

hostname(config)# access-list ETHER ethertype permit bpdu

hostname(config)# access-group ETHER in interface inside

hostname(config)# access-group ETHER in interface outside

HTH,Please rate if it does.

Hi Carl,

Can you share your experience how you solve the bpdu issue on the ASA?

Right now, I'm having the same problem. I have tried using the Ethertype access-list to allow the bpdu, but still cannot. The hit-count on the access-list is not increased.

Thanks a lot for your help.

Regards,
