Usage Information
You can congure 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.
Auto-negotiation is disabled by default. If the CR4 optic fails to come up, use the autoneg option.
If a 40G CR4 interface does not come up, use the following commands:
•
For ACU 40 G cables — use the no intf-type or intf-type cr4 command.
• For CU 40 G cables — use the intf-type cr4 autoneg command.
