Parameters DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide broadcast multicast unicast level pps PPS-RISE [PPSLOW] level kbps KBPS-RISE [KBPSLOW] level LEVEL-RISE [LEVELLOW] action shutdown action drop action none Specifies to set the broadcast rate limit. Specifies to set the multicast rate limit. Specifies to set the unicast rate limit. When the action is configured as the shutdown mode, the unicast refers to both known and unknown unicast packets; that is, if the known and unknown unicast packets hit the specified threshold, the port will be shutdown. Otherwise, unicast refers to unknown unicast packets. Specifies the threshold value in packets count per second. The range is from 1 to 2147483647. If the low PPS value is not specified, the default value is 80% of the specified risen PPS. Specifies the threshold value as a rate of bits per second at which traffic is received on the port. The range is from 1 to 2147483647. If the low KBPS is not specified, the default value is 80% of the specified risen KBPS. Specifies the threshold value as a percentage of the total bandwidth per port at which traffic is received on the port. The range is from 0 to 100. If the low level is not specified, the default value is 80% of the specified risen level. Specifies to shut down the port when the value specified for rise threshold is reached. Specifies to discards packets that exceed the risen threshold. Specifies not to filter the storm packets. Default By default, the broadcast, multicast, and unicast (DLF) storm controls are disabled. The default action taken when a storm occurs is to drop storm packets. Command Mode Interface Configuration Mode. Command Default Level Level: 12.

Parameters
broadcast
Specifies to set the broadcast rate limit.
multicast
Specifies to set the multicast rate limit.
unicast
Specifies to set the unicast rate limit. When the
action
is configured as
the
shutdown
mode, the unicast refers to both known and unknown
unicast packets; that is, if the known and unknown unicast packets hit
the specified threshold, the port will be shutdown. Otherwise, unicast
refers to unknown unicast packets.
level pps
PPS-RISE
[
PPS-
LOW
]
Specifies the threshold value in packets count per second. The range
is from 1 to 2147483647. If the low PPS value is not specified, the
default value is 80% of the specified risen PPS.
level kbps
KBPS-RISE
[
KBPS-
LOW
]
Specifies the threshold value as a rate of bits per second at which
traffic is received on the port. The range is from 1 to 2147483647. If
the low KBPS is not specified, the default value is 80% of the specified
risen KBPS.
level
LEVEL-RISE
[
LEVEL-
LOW
]
Specifies the threshold value as a percentage of the total bandwidth
per port at which traffic is received on the port. The range is from 0 to
100. If the low level is not specified, the default value is 80% of the
specified risen level.
action shutdown
Specifies to shut down the port when the value specified for rise
threshold is reached.
action drop
Specifies to discards packets that exceed the risen threshold.
action none
Specifies not to filter the storm packets.
Default
By default, the broadcast, multicast, and unicast (DLF) storm controls are disabled.
The default action taken when a storm occurs is to drop storm packets.
Command Mode
Interface Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
Use the storm control function to protect the network from the storm of broadcast packets, multicast
packets, or unknown DA flooding packets. Enter the
storm-control
command to enable storm control for
a specific traffic type on the interface.
There are two ways to recover an error disabled port.
The user can use the
errdisable recovery cause
command to enable the automatic recovery of
ports that were error disabled by storm control.
The user can manually recover the port by entering the
shutdown
command, followed by the
no
shutdown
command for the port.
There is only one meter mode (percentage, kbps or pps) that can take effect on an interface. On an
interface, if the later specified meter mode option is different from the previous mode, the previous
configured storms will reset to their default states (disabled in this specification).
Due to hardware limitations, when the meter mode is percentage or kbps:
The action cannot be specified to the shutdown mode.
There are no traps and logs for the drop and none modes.
