nv show bridge domain <domain-id> svi-force-up
Shows if the svi-force-up option is set to on for SVIs in a specific bridge.
The first time you configure a switch, all southbound bridge ports are down; therefore, by default, all SVIs are also down. You can force the SVIs in a specific bridge to always be UP with the nv set bridge domain <bridge-id> svi-force-up enable on option, which is beneficial if you want to perform connectivity testing.
