While any QSFP28-DD port can be used for any purpose, the following table and figure outline the recommended but not required, port order for connecting the chassis with the MX7116n FEM modules to the MX9116n FSE to optimize NPU utilization.
Chassis | MX9116n FSE port group | Physical port numbers |
1/2 | Port group 1 | 17 and 18 |
3 | Port group 7 | 29 and 30 |
4 | Port group 2 | 19 and 20 |
5 | Port group 8 | 31 and 32 |
6 | Port group 3 | 21 and 22 |
7 | Port group 9 | 33 and 34 |
8 | Port group 4 | 23 and 24 |
9 | Port group 10 | 35 and 36 |
10 | Port group 5 | 25 and 26 |
