VIP-NET-M28A Network Switch - USER MANUAL
VERSION 1.0
Traffic Prioritization
Storm Control
A LAN storm occurs when packets flood the LAN, creating excessive traffic and degrading network
performance. Errors in the protocol-stack implementation, mistakes in network configuration, or users
issuing a denial-of-service attack can cause a storm. Storm control prevents traffic on a LAN from being
disrupted by a broadcast, multicast, or unicast storm on a port. In this page, you can specify the
rate at
which packets are received
for unicast, multicast, and broadcast traffic. The unit of the rate can be either
pps (packets per second) or kpps (kilopackets per second).
Note: frames sent to the CPU of the switch are always limited to approximately 4 kpps. For example,
broadcasts in the management VLAN are limited to this rate. The management VLAN is configured on the
IP setup page.
