This sets the packets-per-second rate threshold that, when exceeded by a given traffic type on this port, triggers the switch's storm control action (typically dropping or rate-limiting that traffic). Administrators tune this value to protect the network from broadcast or multicast storms while avoiding false positives on ports that legitimately carry bursts of that traffic type. Setting this object to 5000 for broadcast traffic on an access port means the switch begins storm-control action once broadcast traffic on that port exceeds 5000 packets per second.
