MSTP - Question about Interface and VLAN

Hi,

short question: Under the mstp-configuration I need to specify the interface and also the vlan for which mstp will be active.

So lets assume I have VLAN 15 and the VLAN is configuered at port

ge-0/0/13

ge-0/0/14

ge-0/0/15

ge-0/0/16

But now, I have simply forgotten to add the interface "ge-0/0/16" under mstp  - interface (but the vlan 15 is configured under mstp - vlan)

Will the interface be included in MSTP because the VLAN 15 is configured at mstp  - vlan or what will be the behaviour of MSTP in that situation ?

Thanks in advance, Christoph.
