Broadcast Storm Control

The hiD 6615 S223/S323 supports broadcast storm control for broadcast packets. Broad-
cast storm is overloading situation of broadcast packets since they need major part of
transmit capacity. Broadcast storm may be often occurred because of difference of ver-
sions. For example, when there are mixed 4.3 BSD and 4.2 BSD, or mixed AppleTalk
Phase I and Phase II in TCP/IP, Storm may occur
In addition, when information of routing protocol regularly transmitted from router incor-
rectly recognized by system, which does not support the protocol, Broadcast Storm may
be occurred.
Broadcast Storm Control is operated by system counts how many Broadcast packets are
there for a second and if there are packets over configured limit, they are discarded.
The hiD 6615 S223/S323 provides not only broadcast storm but also control of multicast
and DLF (Destination Lookup Fail) storm. In order to use control of multicast and DLF
storm, use the following commands. Then all configurations of Broadcast storm control
will be equally applied to all VLANs.
To enable multicast storm control and DLF storm control, use the following command.
Command
storm-control { broadcast | mul-
ticast | dlf } RATE [PORTS]
By default, DLF storm control is enabled and multicast storm control is disabled.
To disable multicast storm control and DLF storm control, use the following commands
SURPASS hiD 6615 S223/S323 R1.5
