Hey @blebarro
It sounds like you're experiencing a compatibility or configuration issue with your 40/100 SRBD optic in your 100G switch. Here are some steps and suggestions to help troubleshoot and resolve the issue:
Check Compatibility:
- Ensure that the 40/100 SRBD optic is compatible with both the switch models you are using. Refer to the switch and optic vendor documentation for compatibility lists.
Firmware and Software Versions:
- Verify that both the spine switch and the 100G switch are running the latest firmware and software versions. Sometimes, newer firmware includes bug fixes and support for additional optics.
Port Configuration:
- Check the configuration of the ports on both switches. Ensure that the ports are configured to support the speed and type of optic you are using. For example, some switches require specific commands to enable 40G or 100G modes on certain ports.
Auto-Negotiation:
- Ensure that auto-negotiation is enabled on both ends. Some optics and switches require auto-negotiation to establish a link.
Transceiver Diagnostics:
- Use the switch's diagnostic commands to check the status of the transceivers. Look for any errors or warnings that might indicate a problem with the optic or the port.
- Commands like show interfaces transceiver or show interfaces status(depending on your switch model) can provide useful information.
Cabling:
- Double-check the cabling. Ensure that the cables are properly seated and that they are the correct type for the optic (e.g., multimode fiber for SRBD optics).
- Try using known-good cables that have been tested with other devices to rule out cable issues.
Link Training:
- Some high-speed links require a link training process. Ensure that this process is completing successfully. This might be visible in the switch logs or through specific diagnostic commands.
Cross-Compatibility:
- If you are using optics from different vendors, ensure that they are cross-compatible. Some switches and optics are vendor-locked and may not work with third-party components.
Loopback Test:
- Perform a loopback test by connecting the optic to itself using a loopback cable or adapter. This can help determine if the issue is with the optic or the switch port.
Support and Documentation:
- Consult the vendor's support and documentation for any specific requirements or known issues with the 40/100 SRBD optic and your switch models.
If you have gone through these steps and still cannot establish a link, it may be helpful to contact the technical support team of your switch or optic vendor for further assistance. They can provide more specific troubleshooting steps and may be able to identify any compatibility issues.
Happy troubleshooting!!
