Child interface is not showing on outputs for >show interfaces terse or >show interfaces extensive, even when the same is configured under >show configuration interfaces and SFP is supported, and showing under >show chassis hardware

Interface was configured as VC port, reason why the same is not showing any where as network port:

fpc1:

--------------------------------------------------------------------------

Interface Type Trunk Status Speed Neighbor

or ID (mbps) ID Interface

PIC / Port

1/0 Configured -1 Up 40000 0 vcp-255/1/1

1/1 Configured -1 Up 40000 2 vcp-255/1/0

1/3 Configured -1 Down 40000

1/2 Configured Absent

In order to resolve this issue, we need to set interface as network port using  >request virtual-chassis vc-port delete pic-slot 1 port 3 member 1

You can confirm interface is showing back again using >show interface terse | match "<interface-name>"
