KanREN runs Foundry (Brocade) NetIron XMR 4000's as our primary core  
infrastructure with an MTU of 9216. To make the change (this is  
Foundry-specific), we have to change some system-max settings which  
only take effect once the device has been rebooted (or at least it DID  
require a reboot in the IronWare 3.3.x days). It does NOT reboot  
immediately so you're free to make the change then perform a reboot at  
a convenient time.
