storm-control level (Interface)
This command configures the rising threshold for Storm Control function. Use no
command to return the default settings.
storm-control {broadcast | multicast | unicast} level {
LEVEL
| pps
PPS
}
no storm-control {broadcast | multicast | unicast} level
Default
level pps
PPS
: 131072 packets per second
Command Mode
Interface configuration
Usage Guideline
Only a physical port interface is valid for this command.
The precise suppression level, as a percentage (0 to 100) of total bandwidth of
specific port interface, is not able to be calculated exactly. That is, the current
calculation formula assumes that the packet size of all incoming packets is 1512
bytes.
Examples
This example shows how to configure Broadcast storm control LEVEL by pps
mode. It assigns the pps threshold level of interface eth3.1 for incoming
broadcast packets to 500 and drops the packets that exceed the threshold.
Syntax Description
Broadcast
Set Broadcast rate limiting
Multicast
Set Multicast rate limiting
Unicast
Set Unicast(DLF) rate limiting
level
LEVEL
Specifies the rising threshold as a percentage (0 to 100) of total bandwidth of the
port.
level pps
PPS
Specifies the rising threshold as a rate in packets per second at which traffic is
received on the port. The range of PPS is from 1 to 148810 (for 100 Mbps). For
1000 Mbps, the range is 1 to 1488100 and so on.
