I have brocade icx 7450. I already enabled jumbo frames to increase MTU packets on switch. But unfortunately I am not able to change MTU size of port which I want. When typing after choosing interface ethernet e.g. 1/4/1 and then ip mtu, this command is not recognized.
How I can set up for ports which I wabt MTU packets to 9000. Do I miss something?
