Managing the Switch

Configuring Ports

This switch has 32 ports of which 28 are configured as 40/50-Gigabit ports and 4 are configured as 40/100-Gigabit ports. You can change the ways that these ports are used by using templates to configure all the ports in commonly used ways or by configuring ports individually. Three of the templates that you can use are the following:


Note

The top and bottom ports should run at the same speed. If a speed difference is encountered, the bottom port is disabled.

  • 28 40/50-Gigabit ports and 4 40/100-Gigabit ports (default configuration)

  • 24 40/50-Gigabit ports and 6 40/100-Gigabit ports

  • 18 40/100-Gigabit ports

You can individually configure the ports 1 to 28 as indicated in the following table:

Odd Numbered Port (1 to 27)

Even Numbered Port (2 to 28) below the Odd Numbered Port

40-Gigabit QSFP+ port (default)

40-Gigabit QSFP+ port (default)

40-Gigabit port with 4x10-Gigabit breakout feature

Hardware disabled

100-Gigabit QSFP28 port

Hardware disabled

100-Gigabit port with 4x25-Gigabit breakout feature

Hardware disabled

1/10-Gigabit port using a QSFP-to-SFP adapter in the port

1/10-Gigabit port using a QSFP-to-SFP adapter in the port

Note 

Even numbered port must use the same speed as the odd numbered port in the same vertical pair of ports. Connect the odd numbered port first to set the speed for the vertical pair of ports.

You can individually configure ports 29 to 32 as follows:

  • 40/100-Gigabit QSFP+/QSFP28 uplink port (default)

  • 40/100-Gigabit QSFP+/QSFP28 uplink port can be individually broken out with the 4x10-Gigabit or 4x25-Gigabit breakout feature.
