It says T1 has been created, connected to T0-GW-01 via an automatically assigned subnet of 100.64.64.2/31. Where we can check this interface status?
You can check this in NSX U.I , topology view or under Advanced config of T0 https://docs.vmware.com/en/VMware-NSX-T-Data-Center/3.2/administration/GUID-7891E6E7-606D-4F79-8AB7-... . get interface command will also fetch the same output if you want to check via CLI( Please refer to NSX Edge cli document for the same)
