Why is my Brocade VDX 6720 showing an MTU of 2500 when I have set it in the config to 9126?

Hi, I have a VDX6720 running firmware 3.0.1E. 

 

I have set the MTU on some portchannels to 9216.

When I veiw the interfaces stats for the interfaces in the channel they still show 2500.  Any ideas what can be causing this?

 

Regards

Phil

is probable this is issue is caused due a Defect closed in NOS 4.0.2

Maybe you met the DEFECT000342359,which should be fixed in NOS 2.1.0....

Anyway you can try the steps as: change the MTU to 9000(or other value), then change the MTU to 9216.
