Spirent TestCenter: What is the capability of auto-negotiation on 10G Base-T, 40GBASE-CR4, and 100GBASE-CR10 modules?

  • Spirent TestCenter
  • MX-10G-Cx
  • FX-10G-Cx
  • MX-100G
  • MX-40G
  • FX-100G
  • FX-40G
  • FX/MX-10G-C2|4|8 10G Base-T modules 
    • 1G operation is fully supported 
    • 1G mode can auto negotiate to 1G or 10G but can not advertise both at the same time
    • Known Issue
      • Link will not be established when a 10GBase-T module (MX-10G-C or FX-10G-C) is re-configured to advertise both 10G and 1G operation (the default is to advertise 10G) and the link partner only supports 1G operation.
      • If the link partner only supports 1G operation you must configure the Spirent port to only advertise 1G operation.
      • Dual speed autonegotiation will be added into the next Spirent TestCenter Release, v4.30.
  • MX-100G, MX-40G, FX-100G and FX-40G
    • 40GBASE-CR4 and 100GBASE-CR10 auto-negotiation is not supported
    • Workaround: Disable auto-negotiation on the device under test
