i have cisco switch C3560E Version 12.2(55)SE6, it showing me the mtu on each interface is 9000. when i try to change it globally by using "system mtu 1500" nothing happens. please suggest whats the reason of this mtu size.

check below guide :

If you do not have devices which required MTU 9000, there is no need to enable.
