Which ports on the CE6881 do not support optical modules

On the CE6881, ports outside 13–16 and 25–28 have limitations with certain optical modules, and some 10GE ports do not support specific optical module types.

Ports with Optical Module Limitations

• 10GE Ports 13–16 and 25–28: These ports can support GE optical modules, but after installation, the speed must be manually set to 1000 Mbit/s using the speed 1000 command. All four ports in each group are switched together, meaning configuring one port affects the others .
• Other 10GE Ports: All other 10GE ports can automatically adapt to optical modules, but they do not support OSXD22N00 or LE2MXSC80FF0 optical modules .
• Copper vs Optical: GE copper modules are supported on 10GE ports with full-duplex operation, but half-duplex is not supported. 10GE copper modules are supported in later software versions (V300R024C10 and above) and can operate at 100M/1000M/10GE .

Key Notes

• 40GE/100GE QSFP28 Ports: These uplink ports support optical modules at 40 Gbit/s or 100 Gbit/s. After splitting, only 1-to-4 optical modules or AOCs are supported; high-speed copper cables are not supported .
• Management and Console Ports: The ETH management port (RJ45), console port, and USB ports do not support optical modules as they are intended for configuration, management, or backup purposes .

In summary, ports 13–16 and 25–28 require special configuration for GE optical modules, while other 10GE ports cannot use certain optical module types (OSXD22N00 or LE2MXSC80FF0). Management, console, and USB ports are not compatible with optical modules. This information is critical for planning optical connectivity and ensuring proper port configuration on the CE6881 switch.
