Firepower 1010 and ASA 9.14.2 Spanning-Tree BPUD Guard blocked

[kerstin-534]

Hi,

we have seen that Firepower 1010 and ASA 9.14.2.x has 

Spanning-Tree BPUD Guard blocked port on connected Nexus Switch if at least 2 Ports (different VLANs) connected to same Switch. This does not occur in ASA 9.14.1. Hast anybody seen the same issue ? Regarding to Firepower 1010 documentation there should be no Spanning-Tree running on device.

Upgrade to ASA 9.14.2 and there is the second port (DMZ) on the Nexus Switch going to BPDU blocked, Downgrade to ASA 9.14.1, everything is ok. Upgrade again there is this issue.

Did you find a fix for this issue?

no.

in 9.16.4.19 even with "no switchport" on forepower interface on switch side port is error disabled.
