VIAVI TestCenter: What is the Maximum Supported MTU on VIAVI Cards.

VIAVI TestCenter: What is the Maximum Supported MTU on VIAVI Cards.

• DX Modules • v4.61 - The official maximum supported MTU size is 4K. It may support higher up to 8K depending on certain factors like state of Reassembly buffer, if the buffer is empty or not, or if a lot of traffic being blasted with high rate. This is limitation of the current FPGA implementation for the DX family. • PX3-100G • v4.98 - The official maximum support MTU size is 9k in performance mode • Default mode is less than performance mode. • v5.37 - While testing ISIS with Jumbo LLC the test could run to a maximum of 8166 for MTU Size in Default Mode, if you increase to 8167, the adjacency does not forms due malformed packets sent. • In performance mode this limitation is solved. • v5.48 - Was able to set MTU size 16352 • OSPF came up showing MTU size 16352 • Not that STC stream is not affected by MTU since it is the endpoint. • Also 16004 is the largest frame size of a stream that can be configured.
