I may have to crack open one of my spare 1811s as well... if it's a straight 3prong plug for the fan,
I should think you could grab and mod one from your local computer parts store.

I just want to show that the router do not overheat in any way with case open and fan removed..I still think that in some way there is a bug or the shorted circuit on the pcb do makes that HWmon thinks that the CPU will overheats and actually is not..
If i put the case and still no fan it may overheat..

cramer posted : Agreed. I'm just saying it can do it, but you'll be deep into the sticky part. ("edge of the envelope")

Even without NAT, the 1800's have a hard time doing line rate. Pure routing, line rate still takes over 50% of the cpu. The 2800's have less trouble (@100M), but they really don't have the CPU power for services at those speeds. (coming from someone who converted a PIX config to a 2851 only to see it roll over and die... 28Mbps w/~5k NAT -- pure routing, DS3 is no problem for it. I never tried gig-to-gig on it.)

That's traffic (scp) from VLAN1 to F1 with NAT. Interrupt load floats between 70% and 80%, but that's only one nat session, add in a few hundred (or thousand) and it will cry uncle. scp says the throughput was 10.5-10.9MB/s.

cramer posted : Read the document carefully. Those performance numbers are without any services, and moving 64byte packets (i.e. worst case network traffic.) Performance is a function of traffic and configurationl 70kpps is a baseline for comparing models. (the size of your routing table will effect that number.)

Yes, an 1811 can move 100mbps. Would I recommend it? Of course not. The more services one enables, the more sessions NAT has to track, the more routes put in it... everything will subtract from performance.

Back to the point of the thread... his "crash" isn't a crash; the router is doing exactly what it's programmed to do... shutdown before it melts. Fix the fan and it'll be fine. If the hwmon isn't working, then you have another problem. You aren't going to get cisco to cut you a custom build with the environmental monitor disabled. [they're EOL or I'd say buy smartnet and have it replaced.]

sk1939 posted : Well that's only partially true, it can maintain 100mbps with NAT only, but it also depends on the type of traffic and number of sessions it has passing through it. I know for example that my 2811 can handle 35/35, but it peaks at 100% CPU usage with multiple connections.

»www.cisco.com/web/partners/downl···ance.pdf

Most people here said that 1811 can easily maintain 100mbps pipe with NAT only without any other services and i can confirm this..I have Dhcp enabled and NAT and some opened ports.That's it.I don't stress the router with encryptions, crypto and ZBFW yet..
I have also an 850 that's rated a 5Mbps there .... ? I didn't test it but peple around said it can go to max 25mbps...
1811 is a powerfull router with at least 800mhz processor and 128 mb and i bought because it can do wirespeed...It would be really stupid to be rated ONLY at a poor 35mbps when a 30$ dlinks can pull wire speeds easily and have a cpu around 300mhz or so and 32mb ...
Is the same like single core cpu from a PC and 512mb ram without any antivirus, firewall and other programs running at startup..If you put any programs at startup it will slow down..

As to the question above, unless you are downloading at 72mbps (9MB/s)(how?) which will overwhelm the router and peak CPU usage, then it wouldn't cause an issue. 9Mbps will not crash the 1811.

The fan noise from the J2300 is a bit of a problem. Its got a very high pitched whiney fan in it, and it seems to like speeding up and slowing down a lot so it gets a little annoying after a while. I tried running it with the cover off, but no difference. :-/

This fan noise issue is one of the reason why I prefer to have SRX 100 or 210 instead of J series as home lab equipment. All Juniper JUNOS features are pretty much condensed into the same JUNOS code. So regardless of the appliance, you still have the same thing. As example, you could mock up L2VPN on SRX 100 unlike Cisco where you need to have ASR series to do so :)

But since its a generic x86 (Celeron in fact) based box with a run of the mill 3-wire fan, I could potentially find a slower speed quieter fan to clip on top of the heat sink. Maybe even one with blinky lights to "pimp my Juniper." :-P

As for the SRX instead of M7i, the low end SRX's dont do logical systems, which is the feature I am after - support starts from the SRX3400 it seems, according to this document I am readin. You also need licenses to run them on SRX but not on the M series.

Im looking at co-lo'ing them at work in the comms room instead of home, so I dont think the fan noise will be an issue. That way I can run them all the time, with console access. Unfortunately only console access via the corporate console server on the corporate network, but hey, cant have everything. :-)

said by TomS_:

Looking at picking up an M7i or two soon, logical systems are a really intriguing feature, allowing you to run up to 15 individual routers on a single box, very much like a VM. Good for building complex topologies without the mess! :-)

M7i? Compared to SRX100B you bought, the M7i probably costs 4 times more; still a lot of money for some of us not to mention the fan noise :)

If you want to play around with the virtualization, you can just buy another SRX100 since JUNOS uses the same technology between the routers, SRX firewalls, and EX switches.

TomS_ posted : Juniper is very popular among big ISPs. I remember taking a walk through a very large DC in San Jose California, and I reckon I saw more Juniper kit in there than Cisco.

Even if you dont "switch" from Cisco to Juniper, being multi skilled in multiple vendors can only be good for you when it comes to job hunting. That might be the edge you have over the other guys...

I picked up my first Juniper router back in 2008 or so, just a lowly J2300, and compared to traditional IOS, JunOS blows Cisco way out of the water, especially from a configuration point of view.

If you want something new and cheap, the SRX line is quite competitively priced. I picked up a SRX100B for a little over AUD$500, brand new. It runs all of the latest JunOS versions, whereas my J2300 is limited to 9.3. Newer J series (like the J2320, basically anything thats not a Jx300) also run the latest images but are a bit more expensive.

Still, its good for getting a foot in the door, and I still use my J2300 in my lab. Looking at picking up an M7i or two soon, logical systems are a really intriguing feature, allowing you to run up to 15 individual routers on a single box, very much like a VM.

You can always get another 1811 router off ebay. Or you can switch to Juniper SSG 5 (ScreenOS). SSG 5 with unlimited user license these days is cheap since ScreenOS is going away due to the fact that Juniper's plan is to use JUNOS for their firewall product by starting the SRX line.

I know there are Juniper guys and gals lurks around this forum, so you won't be alone. Furthermore there should be no problem in tackling ScreenOS if you feel you are savvy-enough Cisco person and has at least networking concept understanding.

I found a sealed juniper SSG 5 router on Ebay at 179 pounds in UK and i don't know what to do if i switch to it or still go for a Cisco router if the 1811 will fail completly..I still have my 851 but that is very slow for 100mbit pipe...

Juniper SSG 5 is a decent product that you can do lots of things with. As with any vendor (Cisco, Juniper, or else) you should have a contract with them so you can always open up technical case or at very least have ability to download code (IOS for Cisco, ScreenOS for SSG) to find the stable one.

Ok...
i got more information...

*May 12 20:38:38.043: %ENVMON-3-FAN_FAIL_SYSTEM_HALT: Router traps to ROMMON to avoid over heat by fan malfunction -Traceback= 0x803D4250z 0x803D4450z 0x801110DCz 0x8011499Cz *** System received a Software forced crash *** signal= 0x17, code= 0x200, context= 0x84a76850 PC = 0xffffffff, Vector = 0x200, SP = 0xffffffff

Is unusual this happens now.I am already acustomed with the message from 1 minute to another that the "Fan is malfunctioning"..
The case is open and it stayed many days without reseting itself....
Weird..
Now i got the explanations why i find the router in Romon many times after a self-reset..
Any idea how i can deactivate this auto reset..

According to the error message, the router detected failed fan. From your description, it looks like the failed fan issue has been ongoing one. At this point I think the router can no longer tolerate the issue and demand a fix :)

When there is an active Smartnet contract on the router, simply open up a TAC case to RMA the router for free. If you are unsure of the active Smartnet contract situation, you can always hit ebay to find 1811 fan replacement :)

It may be a problem on the circuit that trip the router to reset or go to Romon..The bad thing is i can't find an explanation why it stay for days without a reboot and sudenly begin to reboot..I played games and torrenting much but i can't find a pattern for the resets...

HELLFIRE posted : Genuine hardware fault... uh-oh, that's never good.

So if I read this right, with or without the RAM the router's still crashing?
