Table of Contents

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.

...

  •   From the Linux shell prompt, run the following command.
Code Block
admin@XorPlus$admin@XorPlus:~$ sudo picos_boot port-layout     
Configure the front panel QSFP interfaces port map options:
    [1]  6x40G_QSFP    * default
    [2]  4x100G_QSFP   
Enter your choice(1,2):

...

NOTE:

  •   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.
  • Under SFP mode, port names look like qe-1/1/x.1 ~ qe-1/1/x.4. For example, qe-1/1/25 is broken into qe-1/1/25.1, qe-1/1/25.2, qe-1/1/25.3 and qe-1/1/25.4.
  • Hardware limitation – if power cycle the switch, wait for 10 - 30 seconds before power on.

Configuration Example

The example below shows the steps for configuring the port mapping mode as 4 x 100G.

Step1         From the Linux shell prompt, run picos_boot port-layout command to configure the port mapping mode to 4x100G.

Code Block
admin@XorPlus$admin@XorPlus:~$ sudo picos_boot port-layout     
Configure the front panel QSFP interfaces port map options:
    [1]  6x40G_QSFP    * default
    [2]  4x100G_QSFP   
Enter your choice(1,2):

...

 After changing the port mapping mode and before restarting PICOS, you need to manually remove the user configuration files /pica/config/pica_startup.boot and /pica/config/pica.conf.

Code Block
admin@XorPlus$admin@XorPlus:~$ sudo rm /pica/config/pica_startup.boot
admin@XorPlus$admin@XorPlus:~$ sudo rm /pica/config/pica.conf

Step4         After changing the port mapping mode, you need to restart PICOS to make the setting take effect.

Code Block
admin@XorPlus$admin@XorPlus:~$ sudo /etc/init.d/picossystemctl restart picos

Verify the configuration

  •   After the system boots, run run show interface brief command to view the interface information.
