Access Layer Switch Storm Control
Storm control enables the switch to monitor traffic levels and to drop broadcast, multicast, and unknown unicast packets when a specified traffic level—called the storm control level —is exceeded, thus preventing packets from proliferating and degrading the LAN. Cisco switches offer a feature known as Storm Control, designed to monitor and control the levels of incoming traffic to prevent disruptions caused by multicast, broadcast, and unicast storms. When we have an excessive amount of broadcast traffic on the network then all devices within the broadcast domain will suffer. The switch has to flood all broadcast frames to interfaces in the same VLAN, hosts within the. Storm control is a security feature on network switches that prevents packets on a network interface from exceeding a predefined threshold. All MS series switches include control plane policing of STP and CDP/LLDP floods to ensure Meraki Cloud connectivity. Note: The Storm control settings will only be visible if the network.
