MRMAC uses an Auto-Negotiation and Link Training (ANLT) block inside the GT Wizard. Currently, the following MRMAC modes support ANLT with GTM Only:
| MRMAC Mode | Description |
|---|---|
| 1x100GE | 100CAUI-4, 100GAUI-1 Only |
| 2x50GE | 50GAUI-1 Only |
| 1x40GE | |
| 4x25GE | Although it is four ports, Master Lane is lane 0. Therefore, AN only performs on Lane 0 (Port-0). |
For additional details, refer to the Versal Auto Negotiation and Link Training Interface User Guide (UG1790) (registration required) and AR000038153.
