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. -- Brad Fleming Network Engineer Kansas Research and Education Network Office: 785-856-9800 x.222 Moblie: 785-865-7231 NOC: 866-984-3662 On Jan 30, 2009, at 11:57 AM, adrian kok wrote:
Hi
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
