Check Text (C-251743r810096_chk)
From the NSX-T Manager web interface, go to Networking >> Segments and for each Segment, view Segment Profiles >> SpoofGuard.
If a Segment is not configured with a SpoofGuard profile that has Port Binding enabled, this is a finding.
Fix Text (F-55134r810095_fix)
To create a segment profile with SpoofGuard enabled, do the following:
From the NSX-T Manager web interface, go to Networking >> Segments >> Segment Profiles >> Add Segment Profile >> SpoofGuard.
Enter a profile name, enable port bindings, and then click "Save".
To update a Segments SpoofGuard profile, do the following:
From the NSX-T Manager web interface, go to Networking >> Segments and click "Edit" from the drop-down menu next to the target Segment.
Expand Segment Profiles, choose the new SpoofGuard profile from the drop-down list, and then click "Save".
