Here is the procedure to turn off flow control for one specific port on your brocade switch with CLI:
Let’s consider we want to configure 1/2/1 port for example. (10G ports are numbered as 1/2/1, 1/2/2, 1/2/3, etc)

- Connect to the switch via the console port (or telnet/ssh when available)

- Get granted privileges (might return an error if it has been previously done):
# enable

- Switch to config mode:
# configure terminal

- Select the port you want to configure:
# interface ethernet 1/2/1

- Disable flow control for that specific port:
# no flow-control

- Exit current level:
# exit

- Check the current configuration for that port:
# show interfaces ethernet 1/2/1

- Make sure you can see “Flow control is disabled” in the output.

- Save the current configuration by writing it to flash memory (if you do not, modifications will be lost at reboot/shutdown):
# write memory

Whenever you need to enable jumbo frames support in order to send more than to 1500 bytes of payload per packets. (up to 9000 bytes with jumbo frames)
After getting granted privileges and switch to config mode, please just enter the following command.

- Enable jumbo frames
# jumbo

- Save the current configuration by writing it to flash memory (if you do not, modifications will be lost at reboot/shutdown):
# write memory

- Reboot the switch as it takes one reboot in order to enable jumbo frames:
$ reload
