Description (partial)

When enabling 'jumbo-frame reservation' on ASA, you will be asked to reload ASA. After reload, ASA will not show 'jumbo-frame reservation' enabled.  Command will be seen in start-config however not in running-config. Attempting to enable the command again will provide the following warning:

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
