[AusNOG] Nexus does not receive BPDU at all

[Andy S.]

Hi guys,

Scratching my head all over this, we have just rolled out new Nexus 9000,
it has trunks connected to legacy Cisco 3560.

Trunk status is up and connected, however on a whim I issued show spanning
int e1/4 detail and saw this:

   BPDU: sent 1487329, received 0
   BPDU: sent 1487326, received 0
   BPDU: sent 1487337, received 0
   BPDU: sent 1487355, received 0


We certainly don't have BPDU Filter turned on (even if we do, that will
prevent sending and receiving). No fancy config elsewhere. This is a (site
to site) metro ethernet service from Vocus, if that helps.

Vocus said they didn't do anything with BPDUs.

Any help is appreciated.

Regards,
Andy
