Information
You can configure the interface type as CR4 with auto-negotiation enabled. If a DAC cable link is down,
you can resolve the issue by setting the interface type as CR4.
If the CR4 optic fails to come up, use the autoneg option.
On 100-Gigabit Ethernet interfaces, CR4 auto-negotiation is enabled by default.
