Re: can I ask mtu question

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.

What is max mtu in jumbo frame?
ls it 9000?

Do I need to reboot the switch to take effect after
setting up it?

if it doesn't need to reboot, How can I know the
switch is running fine in this mtu 9000? eg: cisco
any tools to check?

Thank you for your help
