switch         port bezel-intf

-------------- ---- ----------

Leaf1          1    1          

Leaf1          2    2          

Leaf1          3    3          

Leaf1          4    4          

Leaf1          5    5

...

Leaf1          49   49         

Leaf1          50   49.2

Configuring Ports for Different Throughput

By default, ports on the switches are configured as 40GbE ports. You can also use them as 4 x 10GbE with the right transceiver. To refer to the 40Gb port, use the last port number of the port group. For example, the first 40Gb port, in the example above, is referred to as port 49 for 40GbE use and as ports 49, 50, 51, and 52 for 4/10Gb use.

If you want to change the 40Gb port to 4x10Gb functionality, use the following command sequence:

CLI network-admin@Leaf1 > port-config-modify port 49-52 speed 10g

To change the port back to 40Gb operation, use the following command sequence:

CLI network-admin@Leaf1 > port-config-modify port 49 speed 40g

 

The default port speed is 10G and you can modify the parameters of a port:
