'show interface trunk' output

My question is..

interface Gi0/1 on access switch (Switch A) configured as trunk port allowing multiple vlans (say vlan 100-105)

Now, this interface Gi0/1 on switch A has no issues and configured fine.

Another switch B connected to Switch A and working fine.  both sw A & sw B up and working fine

But,  switch B is now say disconnected from Switch A  which causes the interface Gi0/1 on SW A go down.

when I do a "show interface trunk" on Switch A, will the output show trunked vlans 100-105  or the output will not show  the trunked vlans as the interface on Switch A is down  because the Switch B is disconnected???

Basically, all I want to know is   when an interface configured for trunking multiple vlans go down   will the "show interface trunk"  command list those vlans 100-105 in the output  ???

Thanks for  looking into my q

When the link is down, you will get a "blank" output to the command "sh interface trunk".
