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:

  • Speed - you can disable the port or set the speed to 10m, 100m, 1g, 2.5g, 10g, or 40g
  • Egress rate — limit the egress rate or set to unlimited.
  • Ethernet mode type — set the mode type to 1000base-x, sgmii, autonegotiate
  • Enable or disable a port
  • LACP priority — between 1 and 65535
  • Reflect — received frames are reflected for loopback testing.
  • Edge-switch — Specify if the port connects to another Netvisor One device or is an uplink to a third-party switch or host.
  • Pause — pause traffic on the port.
  • Description — description of the port
  • Loopback — specify loopback
  • Mirror-receive — receive mirrored traffic only.
  • MAC address — specify a MAC address for the port.
  • VLAG failover — specify if the port is used in VLAG failover.
  • Sending port number — specify if the port number is sending traffic.
