The six interfaces of QSFP+ and QSFP28 on the switch, with port numbers from 25 to 30, form an interface group. You can configure the port mapping mode of this interface group as required, the value could be 6 x 40G or 4 x 100G.

...

  • 4 x 100G: In this port mapping mode, the four QSFP28 interfaces numbering 25, 26, 29 and 30 work at 100G mode and the other two QSFP+ interfaces numbering 27 and 28 are unavailable. In this mode, the interface names of the four QSFP28 interfaces are he-1/1/25, he-1/1/26, he-1/1/29 and he-1/1/30.

  •   Run this command in Linux shell.
  •   To run this command, you need root privileges.
  •   The default setting is 6x40G_QSFP.
  •   After changing the port mapping mode, you need to restart PICOS to make the setting take effect.
  •   Manually remove the user configuration files /pica/config/pica_startup.boot and /pica/config/pica.conf after changing port mapping mode and before restarting PICOS. 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.
