Description (partial)

Symptom:
EICAR file is not getting blocked. The Firepower is incorrectly categorizing the SMBv2 traffic as AP ID imo.im (685) instead of NetBIOS-ssn (SMB)(755). We are seen this issue only on one site and not all of the sites.

Conditions:
Specific for traffic going from the Main site to the remote Blacksburg site.
