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.
1. Configure anti-broadcast, IPv6 filter, UPnP filter and port isolation settings.
Security command Parameter Description
Switch(config)# security anti-
broadcast polling-interval [3-
300] [3-300] Specify a time interval for the frequency of

refreshing broadcast traffic. The allowable
time interval value is between 3 and 300
seconds.
