I have Adtran Netvanta 1560 Switches deployed in a customer network. I understand the 10 GB Port can manually (Thru software) be configured to 1 GB. My question is when you reconfigure the port from 10 Gb to 1 GB do you have to power cycle or push a button in somewhere to make the 1 GB configure change take effect?(actually change from 10 Gb to 1GB0
Thank You

Once you inpout the command as below, it should take affect. You may need to modify the upstream device to be hardcoded and not trying to auto config the speed:
1560 Switch 1 and upstream switch
!
interface 10GigabitEthernet 1/5
switchport mode trunk
qos trust tag
speed 1000
