Spirent TestCenter: How are the ports splitted into when changing speeds in a 400G 2-port module.
When you change speeds in a 400G 2-port module this is the way you will see each port being splitted into:
200G: Each 400G port will be divided into 2 x 200G lanes
100G: Each 400G port will be divided into 4 x 100G lanes
* 50G: Each 400G port will be divided into 4 x 50G lanes (You need to change the port to Density-Mode, otherwise by default it will give you 4x50 only)
40G: Each 400G port will be divided into 2 x 40G lanes
25G: Each 400G port will be divided into 8 x 25G lanes
10G: Each 400G port will be divided into 8 x 10G lanes
* NOTE: Only newer modules (Refer to
, 5.14 release notes section that mentions the 80 part number included) supports 8x50 in Density Mode, older modules don't have Density Mode and then will show you only 4x50G
In GUI, when set to 400G you will see ports 1/1 and 1/9, if you changed it to 200G you will see ports 1/1, 1/2 and 1/9, 1/10 and so on...
