Examples

Example 1: The YAML snippet below demonstrates how to configure link-level policies. This includes setting the link_delay_interval and link_debounce_interval parameters. These are important for managing the “Port Bring-up Delay” required by various Line Cards, such as the Oracle Exadata CX5 Mellanox NICs. Both link_delay_interval and link_debounce_interval values are specified in milliseconds (ms), and link_delay_interval is set to 0ms by default.

  access_policies:
    interface_policies:
      link_level_policies:
        - name: 10G-CX5
          speed: 10G
          link_delay_interval: 10
          link_debounce_interval: 110
          auto: true
          fec_mode: inherit

Example 2: The YAML snippet below demonstrates the flexibility of converting a fiber port into a copper port. By specifying the physical_media_type as sfp-10g-tx, we can easily integrate copper-based devices into the network infrastructure. The physical_media_type field can be set to either auto or sfp-10g-tx.
