"system mtu jumbo" command in CGS2520 switch

Dear all, May I know if the "system mtu jumbo" command will appear in the "show running-config" of a CGS2520 switch please?  Or it will be hidden from the IOS config files? Thanks for your attention in advance!

Hello,

 

it won't show up in the running configuration. The below applies:

 

"The system MTU setting is saved in the switch environmental variable in NVRAM and becomes effective when the switch reloads. The MTU settings you enter with the system mtu and system mtu jumbo commands are not saved in the switch IOS configuration file, even if you enter the copy running-config startup-config privileged EXEC command. Therefore, if you use TFTP to configure a new switch by using a backup configuration file and want the system MTU to be other than the default, you must explicitly configure the system mtu and system mtu jumbo settings on the new switch and then reload the switch."
