Cisco Catalyst switches provide a feature termed "," which allows an administrator to suppress excessive inbound unicast, multicast, or broadcast traffic on layer two interfaces. This can be handy to protect against broadcast storms resulting from spanning tree misconfiguration, or even unicast storms created by malfunction host NICs.
On each interface, a maximum threshold can be configured in bits or packets per second, or as a percentage of the interface bandwidth. If incoming traffic of the specified type exceeds its threshold during a polling interval (one second), traffic is blocked until the incoming rate drops below the configured falling interval. Consider the following traffic graph:
In interval T0, inbound traffic is accepted as its rate never exceeds the rising threshold. In T1, the rising threshold is exceeded, and the switch makes a note to block incoming traffic for the next interval. In T2, traffic is blocked, but the switch continues to monitor the incoming rate. Although the rate has fallen below the rising threshold, it still exceeds the falling threshold, so the switch will continue to block traffic for the next interval.
During T3, traffic stays below the falling interval, so the switch removes the blocking for T4. Although traffic in T4 exceeds the falling threshold again, traffic will not be blocked for the next interval as the rising threshold hasn't been exceeded.
Configuring storm control on an interface is simple. At a minimum you'll need to specify a traffic type (unicast, multicast, or broadcast) and a rising threshold:
Switch(config-if)# storm-control broadcast level bps 1m 500k
In the above example, we have configured storm control for broadcast traffic with a 1 Mbps rising threshold and a 500 Kbps falling threshold. Note that specifying a falling t if omitted, the falling threshold will default to the value of the rising threshold (effectively removing it).
show storm-control displays interfaces configured with storm control and the state of each:
Switch# show storm-control
Filter State
-------------
-----------
-----------
----------
Forwarding
Observe how the output changes when the upper (rising) threshold for broadcast traffic is exceeded:
Switch# show storm-control
Filter State
-------------
-----------
-----------
----------
Additionally, the switch will generate a log message notifying administrators of the detected storm:
%STORM_CONTROL-3-FILTERED: A Broadcast storm detected on Fa0/5. A packet filter action
has been applied on the interface.
When the incoming rate drops below the lower (falling) threshold, the interface filter returns to forwarding:
Switch# show storm-control
Filter State
-------------
-----------
-----------
----------
Forwarding
48.81k bps
Lastly, the storm-control action trap command can be used under interface configuration to send SNMP traps in the event of a storm rather than the default behavior of blocking incoming traffic.

Hi Jeremy,
which method or tool do you use for testing the storm-control broadcast? Any information/hint for me?
Norbert Boehm
November 27, 2008 at 9:02 p.m. UTC
@Norbert: I like
for stress testing. In fact, I used it to test the configuration shown in this article. You can create a static ARP mapping some IP to FF:FF:FF:FF:FF:FF to test broadcasts at layer two.

Is there any guidance on sensible values to use for the thresholds?
December 9, 2008 at 7:11 p.m. UTC
Coming from a large network, I can tell you that the hardest part is finding a sensible value that works in your enterprise for broadcast and multicast storm control. I have found the best bet is to start with a low number and work your way up, also look at traffic patterns and captures on that switch, which is also helpful in determining a faulty nic, or misconfigured MLB multicast device,

Storm-control can process both ingree and egress traffic???
sonic (guest)
February 3, 2010 at 10:25 a.m. UTC
vijay - as I know, it works only for ingress. if your traffic is comming from core, this won't help you.
Paul - did you find any post with sensible values ??

Try psense 1.2.3, with CARP + LoadBalance (Failover Mode), and a rule permit any/any from LAN to WAN. You will get a pretty broadcast storm to test...
Be carefull a TenGigabit network can be also vulnerable with this snowball...

"storm-control action trap" doesn't change default behaviour and blocking does happen when storm is detected. all it does is adding notification using SNMP traps that storm is in progress.

Am I reading this correctly?
If is set the "storm-control broadcast level 30.00" without the additional "falling threshold" parameter the command is pretty much useless.
Is this correct?
thank you.

January 13, 2014 at 12:02 p.m. UTC
in the case where the storm control action is set to trap, but when the threshold is exceed, instead of of the trap to alert the administrator of the storm that has been detected, the switch behaves as if the action set is shutdown. What would you say caused this behavior?

Is there a way to enable storm-control but as a watch only...so you can see what is normal traffic to use as a baseline.
January 18, 2016 at 5:03 a.m. UTC
This example really helped. I was able to monitor the Unicast Storm-control, by connecting to PCs together between a switch and sending a 1.5GB
movie file across the link. At times it would be transmitting at 15MB per second, but when I set the uprised threshold to 5MBps & Lower to 3Mbps.... I was able to see it work well.
willy (guest)
May 4, 2016 at 1:53 p.m. UTC
You forgot to mention that stormcontrol in bps is only supported on 3850 & IOS XR devices. Catalyst 6500 and Nexus 5000, it is still a percentage with 2 decimals of the interface bandwidth, rendering it nearly useless. On a 10GE, 0.01% is still 100 Mbps of broadcasts....

dante--2 things. If the toner cart says "empty", and is not, you can get a little more life out of it by replacing the fuse at eh lead edge, to the left on the cart. Use a .1A (100mA) 250V fuse. It blows upon insertion into the printer and counts down. Good luck. Any questions, you may email me as well. :-)PCRMike
by pcrmike on Nov 21, 2006 at
..............there isn.t any fuse in it........SO????????
by Anonymous on Jan 11, 2007 at 12:09pm
Then it is a starter cartridge sir. The first toner in those only goes for about 800-1K pages, and actually runs out of toner. It is not a pop-and-fill type toner either. Your best bet is buy a replacement, and when you go to put it in, look at it, see the fuse, buy one like it and after it says out, pop it in for the rest of the toner life. :-)PCRMike

From Samsung site:1. Press MENU # 1 9 3 4 in sequence rapidly. The LCD panel should now display TECH. 2. Press MENU, and then press ENTER. The LCD panel will display Tech Mode. 3. Press the left arrow (&) button once. The operator panel will display NEW CARTRIDGE. 4. Press ENTER. The operator panel will display [YES]. 5. Press ENTER. The toner warning message should be gone. 6. To exit TECH MODE, press MENU # 1 9 3 4 in rapid succession, as if you were dialing a phone number. The operator panel should no longer display TECH. If problem persists, there may actually be a problem with either the toner cartridge or the SCX-4216F. Works for SCX-4521F

Does anyone know how to reset a Samsung SCX 4828FN? Using the instructions of Anonymous above on the 4828 does not work. IN fact, using the instructions above does get you into Tech mode, but pressing the back key does not provide the option of new cartridge. By the way, I am using the starter cartridge. I have filled the toner and the printer is still printing despite showin toner empty. I am far from being an expert on this, but it could keep working this way. However, the flashing red light showing toner low/empty is annoying. Any advice anyone has on how to get rid of this toner low message would be appreciated. You can contact me directly at Thank you!Ric

CHANGE TONER SAMSUNG SCX-4521FInstructions for inserting a toner cartridge in the printer SAMSUNG SCX-4521F when this has been refilled or if a cartridge is not original.The Samsung SCX-4521F printer only recognizes the original cartridges SAMSUNG and rejects those who despite being originals have been refilledWhen this happens, on the screen printer appears the mesage "TONER EMPTY" and every time you turn the printer on you will hear an annoying beep. To prevent this from happening, when you replace a cartridge that is not genuine or has been refilled, you must enter the unlock code and follow the steps listed below:"Unlock Code"1. Press the "MENU" option followed by "#" and enter the code "1934".2. The screen should display the word "READY"3. Move with the arrows until you find the option "NEW CARTDRIGE"4. Choose "YES" by pressing "OK"5. Press again the key "OK"6. Turn the printer off to restart the machine.

It sounds like its about to start printing, then makes a fax like noise (I dont use it as a fax) then says paper jam. Im thinking the feeder is having a problem.Any help I would appreciate.Thanks

Hi. I have had my samsung scx 200 for some years now and have changed the toner several times without any problem.Suddenly we discover that when we photocopy it comes out with a half page.We though maybe the toner was low so we got it changed but the same thing continues. No paperjam, no blurs but only half page. The half page is as clear as normal. What can i do. I so love this little piece of technology which had never let me down!

HI,I recently purchased Samsung SCX 3201 g printer Yesterday i refilled this printer but after refilling its not working its showing end of life of toner error message" i also had talked with Customer care, but they said it has chip feature which has maximum print limits so that we cant print more than 2000 pages with a single toner means whenever its toner gone empty we have to buy a new toner which is around 3500 Rs so please tell me is there any way to reset this printer becasuse my toner is full but printer doesnot sence it due to the print limitationI also recommond to everyone please dont buy samsung printer because it has a chip feature. So that i suggest everyone to buy only HP printer which come without chip so that you can also reuse the refill toner

No matter what you do with the cartridge, if there's no toner in it, it isn't going to print.

Very often when I want to print, the printer just ignores it! In that case I have to switch it off and then on again and it prints ok. It does it so often it is very annoying.It is like it needs to be woken up. How can I keep it "awake" at all times?

Well get a new cartridge and it will be fine. You can't print without toner you know.
