Aruba CX Jumboframe disable

Hi,

I have first Aruba CX Switch (6300). How can I disable Jumboframes?

I have set below commands to ArubaCX, but still when I check logs from Huawei, where this ArubaCX is connected to, it shows Jumboframes both input and output. (if I disable Huawei's Jumboframes, it shows giant frame errors). Other switches are Ciscos and no jumboframes coming from them.

swi042(config)# int 1/1/50

swi042(config-if)# mtu 1500

swi042(config-if)# int 1/1/49

swi042(config-if)# mtu 1500
