The NSX-T Tier-0 Gateway must be configured to have all inactive interfaces removed.

Description
An inactive interface is rarely monitored or controlled and may expose a network to an undetected attack on that interface. If an interface is no longer used, the configuration must be deleted.

Who does this work

18 NICE work roles and 10 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-251746r810122_chk)

From the NSX-T Manager web interface, go to Networking >> Tier-0 Gateways. For every Tier-0 Gateway, expand the Tier-0 Gateway >> Interfaces, and click on the number of interfaces present to open the interfaces dialog. Review each interface present to determine if they are not in use or inactive. If there are any interfaces present on a Tier-0 Gateway that are not in use or inactive, this is a finding.

Fix Text (F-55137r810121_fix)

Disable multicast PIM routing on interfaces that are not required to support multicast by doing the following: From the NSX-T Manager web interface, go to Networking >> Tier-0 Gateways and expand the target Tier-0 gateway. Expand "Interfaces", then click on the number of interfaces present to open the interfaces dialog. Select "Delete" on the unneeded interface, and then click "Delete" again to confirm.
