Is there any way to avoid broadcast/multicast storm in my network?
Answer:
Enable the Storm Detect / Storm-Control feature on your managed switch.
- Per-port monitoring – Each port can watch broadcast and/or multicast traffic by percentage of link bandwidth or packets per second.
- Automatic shut-off – When traffic on a port exceeds the threshold you set, the switch immediately disables that port to stop the storm.
- Timed recovery – Optionally configure the switch to re-enable the port after a user-defined interval.
Example
- Ports ge1 and ge2 are configured with storm-control thresholds of 80% link utilization or 3000 packets per second for both broadcast and multicast traffic.
- If either port exceeds either threshold, the switch immediately disables that port to halt the storm.
- When the recovery timer is set to 10 seconds, the port automatically re-enables itself 10 seconds after being shut down.
