[c-nsp] MTU wierdness

[Michael Robson]

I have a 6509 (with Sup720-3B) that contains 2 x WS-X6704-10GE blades  
where I am trying to set the MTU to be 1504 on each of these  
interfaces. On one blade it will only allow me to set the MTU to 9216  
if the interface is a switchport, the 1504 MTU size only becomes an  
option when it is changed to a routed port. Since this is not the case  
on other 6509s we have, anyone have an idea why this might be  
happening (it maybe worth noting that, at present, one of the other  
ports is a routed port with MTU of 9216)?

Thanks,


Michael
