Configuration Notes of Configuring Port Breakout and Merge

When configuring port breakout and merge on a device, pay attention to the following points:

•   When performing the following operations, you need to restart or reboot the system to make the setting take effect.
  • Mode change between SFP, QSFP and FLEX
  • Port breakout
  • Port merge

•  When switching between SFP and QSFP mode, before restarting the system, you need to manually delete the configurations of the unavailable interfaces in the new mode, thus to make sure that the configuration file can be loaded normally when the system boots up.

•  When performing the port merge operation, before restarting the system, you need to manually delete the configurations of the unavailable interfaces in the new mode, thus to make sure that the configuration file can be loaded normally when the system boots up.

•  When switching from QSFP or SFP mode to FLEX mode, the user configuration will be removed and the default configuration file will be loaded.

• There is no command to switch from FLEX mode to QSFP or SFP mode. If you want to achieve this, you can manually delete the user configuration files /pica/config/pica_startup.boot and /pica/config/pica.conf and restart the system. The system will the boot up in the default QSFP mode. Be cautious that all the user configurations will be lost after these operations. We suggest you backup the configuration file before proceeding with these operations.
