FabricPath packet size

Anybody,


My input pakages changed from Eternet to DCE, console was complaining about the packet size. I had to change from 1522 to 2048 in AMD (these are defaults), everything in fine now (-;


 


Looking at the packet max size 1514 + fabric header 14 = 1528, did somebody make a calc error. It would nice to have 1528 as max?

Henk,

The AMD supports only fixed max packet sizes. 1522 is sufficient in most cases, when jumbo frames or tunneling (like CFP) is used it needs to be increased to the next predefined value, i.e. 2048. Arbitrary MTU sizes are not supported.

Regards,

Wojtek.
