The configuration below takes effect immediately, but does not persist if you reboot the switch. Restarting the switchd service causes all network ports to reset, interrupting network services, in addition to resetting the switch hardware configuration.Īlternatively, you can run the following commands. When you update the /etc/cumulus/nf file, you must restart switchd for the changes to take effect. # Storm Control setting on a port, in pps, 0 means disable For example, to enable broadcast storm control for swp1 at 400 packets per second (pps), multicast storm control at 3000 pps, and unknown unicast at 500 pps, edit the /etc/cumulus/nf file and uncomment the storm_control.broadcast, storm_control.multicast, and storm_control.unknown_unicast lines: sudo nano /etc/cumulus/nf To configure storm control for physical ports, edit the /etc/cumulus/nf file. On Broadcom switches, ARP requests over layer 2 VXLAN bypass broadcast storm control they are forwarded to the CPU and subjected to embedded control plane QoS instead.Storm control is not supported on a switch with the Tomahawk2 ASIC.Resource Diagnostics Using cl-resource-query.
