Known Issue: Interface Incompatibilities

Due to hardware restrictions, some of our traffic interfaces do not interoperate with some hardware (e.g. restrictions to SFP modules, restrictions to direct-attached-cables...).
In this article we list incompatibilities known to us.  If you encounter other equipment not working with ByteBlower, please inform us using our support portal.

ByteBlower 3100/3200

Due to our hardware vendor, we are restricted to use Intel SFP+ modules

ByteBlower 4100

• Customers reported issues with Twinax DAC-cables.
• We've noticed issues with 1Gbit/s SFP tranceivers.
  • Copper SFP (1Gbit/s) cause systrem crashes.
  • No traffic was possible over Fiber SFP (1Gbit/s)
• 10Gbit/s NBASE-T SFP+ tranceivers have limited connectivity. Check essential connectivity before using these with the ByteBlower 4100. For example:
  
  • No traffic was possible between the 'native' 10Gbit/s on the M4300
  • No issues were reported between 2 copper SFP+ of the same manufacturer

ByteBlower 5100

• No known issues. Do note that at the time of writing (Oct 2020) there a number of competing 100Gbit/s Ethernet standards.
  Don't hesitate to contact us with questions or to report your experience.

Netgear M4200

This switch is used as 8 port NBASE-T add-on. This unit is supplied with a custom configuration for the ByteBlower systems. This config is tested continuously.

• Only use Optic trancievers on the SFP+ ports.
  No functional copper SFP+ (NBASE-T) tranceivers found yet.

Netgear M4300

This is also called the Flex switch due to its flexibility in configuration. Following limitations were found.

• Copper 10Gbit/s SFP+ (NBASE-T) won't negotiate to lower speeds. Connect these transceivers only with other 10Gbit/s links.

Allied Telesis x950 28xsq

This switch is used for the 100Gbit/s ByteBlower 5100.

• Copper 10Gbit/s SFP+ (NBASE-T) won't negotiate to lower speeds. Connect these transceivers only with other 10Gbit/s links.
