Discussion

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.

Check Content

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

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.
