VLANs Trunk shutdown from one side

I have two switches on which I created twoVLANs. There's also a trunk link between them.

I shutdown the trunk port on side A.

No more VLANs are detected on the local trunk port

However, side B’s trunk port is still untouched and it shows allowed VLANs on the trunk, as if nothing special has happened:

So even if the trunking seems to be OK on one switch, we should check the whole trunk across switches.
