Brocade VDX 6730-60-F MTU on the port-channel members

I am having interesting problem with Brocade VDX 6730-60-F


I have a port channel configure with MTU 9214


But I noticed that individual ports from that channel seems to have MTU 2500 and I am not able to change that, and as a result i am not able to send packets across without them fragmenting.


Am I missing something obvious?


PS: If i try to join port with mtu set to existing or new channel I get error that MTU first hast to be reset.



interface Port-channel 10
 vlag ignore-split
 mtu 9216
 description 10
 switchport mode trunk
 switchport trunk allowed vlan all
