Storm-Constrain Control - HP 3600 v2 Series Command Reference Manual

An upper threshold must be greater than or equal to the corresponding lower threshold. HP does not
recommend configuring the same value for the two thresholds.
Examples
# Enable unknown unicast storm control on Ethernet 1/0/1, setting the upper and lower thresholds to
200 pps and 150 pps.
<Sysname> system-view
[Sysname] interface ethernet 1/0/1
[Sysname-Ethernet1/0/1] storm-constrain unicast pps 200 150
# Enable broadcast storm control on Ethernet 1/0/2, setting the upper and lower thresholds to 2000
kbps and 1500 kbps.
<Sysname> system-view
[Sysname] interface ethernet 1/0/2
[Sysname-Ethernet1/0/2] storm-constrain broadcast kbps 2000 1500
# Enable multicast storm control on Ethernet 1/0/3, setting the upper and lower thresholds to 80% and
15%.
<Sysname> system-view
[Sysname] interface ethernet 1/0/3
[Sysname-Ethernet1/0/3] storm-constrain multicast ratio 80 15

storm-constrain control

Syntax
storm-constrain control { block | shutdown }
undo storm-constrain control
View
Layer 2 Ethernet interface view
Default level
2: System level
Parameters
block: Blocks this type of traffic, while forwarding other types of traffic. Even though the interface does
not forward the blocked traffic, it still counts the traffic. When the blocked traffic is detected dropping
below the lower threshold, the port begins to forward the traffic.
shutdown: Shuts down automatically. The interface shuts down automatically and stops forwarding any
traffic. When the blocked traffic is detected dropping below the lower threshold, the port does not
forward the traffic. To bring up the interface, perform the undo shutdown command or disable the storm
control function.
Description
Use storm-constrain control to set the protective action to take on an Ethernet interface when a type of
traffic (unknown unicast, multicast, or broadcast) exceeds the upper storm control threshold.
Use undo storm-constrain control to restore the default.
By default, no action is taken on an Ethernet interface when a type of traffic exceeds the upper storm
control threshold.
