WARNING: jumbo-frame support has been disabled due to insufficient 
memory. Try disabling jumbo-frame support with 'no jumbo-frame 
reservation' and then enabling it again with 'jumbo-frame reservation'. 
Save the running-configuration and perform a reload.
Note: jumbo-frame support will be enabled after the running-config is 
saved and the system has been rebooted
