2.6.18 Security Command
When a device on the network is malfunctioning or application programs are not well designed or
properly configured, broadcast storms may occur, network performance may be degraded or, in
the worst situation, a complete halt may happen. The Managed Switch allows users to set a
threshold rate for broadcast traffic on a per switch basis so as to protect network from broadcast/
multicast/ unknown unicast storms. Any broadcast/multicast/unknown unicast packets exceeding
the specified value will then be dropped.
Configure anti-broadcast, IPv6 filter, UPnP filter and port isolation settings.
