I have 3750 stack with 4 switches.
I am trying to make change some port to new VLAN, but switch 2 & 3 new change never works, the ports stick with old VLAN. Other two switches works as I expected on new changed VLAN.
Tried to reboot, no progress.
Any idea

Can you post your commands to change the VLANs?

Now
Interface GigabitEthernet3/0/25 and Interface GigabitEthernet3/0/26 are changed to different vlan (308 and 324) , but previous VLAN 107 still traffic that ports..
#sh vlan confirmed the changes (at beginning, it does not show up the changes, after reboot system, it shows up, but not effect). Switch 1 and 4 ports changed to new vlan , it works. , any port changes on switch 2 and 3 not working, still with previous VALN 107
#sh vlan
