After enabling web proxy on a CCR1072 I'm seeing that it loads only one core up to a 100%, while others do nothing. Is there a way to fix this?

CCR-1072, 6.34rc39 Just now got this message in my console: jan/19/2016 10:25:21 system,error,critical System rebooted because of kernel failure jan/19/2016 10:25:21 system,error,critical router was rebooted without proper shutdown, probably kernel failure I can only attribute this to enabling fastt...

Here's the diagram:



Current Firmware 3.27 on both CCRs

We're seeing pretty weird situation doing NAT on our Linux boxes after CCRs. After we started using CCRs as BRASes we started seeing short sporadic traffic drops on our NAT boxes for no apparent reasons. One CCR is 6.33.3. The other is 6.33.5. Here's our scheme: - A bunch of BRASes that do PPPoE+Sha...

The SSH problem occurred once again. Here's the output of ssh -v and tcpdump: % ssh -v admin@10.1.1.1 130 ↵ [12:10:13] OpenSSH_6.9p1 Ubuntu-2, OpenSSL 1.0.2d 9 Jul 2015 debug1: Reading configuration data /etc/ssh/ssh_config debug1: /etc/ssh/ssh_config line 19: Applying options for * debug1: Connecti...

Sorry, I had to reboot the CCR before I had a chance to actually run a sniffer or 'ssh -v', since a lot of script logic was tied to being able to SSH to a device. The service failure happened completely on its own early in the morning and had nothing to do with any key regeneration or anything like ...

Hi,

For some weird reason SSH server stopped working.
I was unable to find any relevant alerts in logs.
Disabling/enabling SSH service does not help.

Web interface is accessible.
OS version is 6.33.3.

Any ideas?

Hi, 3000 users online is fine, but how much traffic they consume? I'm right now running 200 users and 1 core reaches 80%, 3-4 Cores are at 10% and rest are 0 or 1. Do you think that if 1 core reaches 100% is actually a problem and some service, for some customer degrades? Hi marlowbg, At peak momen...

All right, so here's a quick summary of our testing: At about 3900 online pppoe sessions and ~1900 shaping queues we started seeing very high cpu load for all 72 cores (and at some point we saw them ALL busy in the range between 90% and 100%). We also did speed tests: one under the account with spee...

Ok, so several hours ago, during night time, we set our CCR1072 up as a pppoe server. And are now monitoring the load. So far we diverted around 3.5k pppoe users on it. Here are the stats. Active sessions: /ppp active print count-only 3548 Queues: /queue simple print count-only 1713 Filters: /ip fir...

You shouldnt put more than 1000 users on a single CCR. You need 10+ CCRs (either 1036 or 1072 wont matter) to have 10k+ users terminated. RouterOS is simply not multi-threaded enough for such a scenario. Really? Is that your personal experience? Because before actually buying a CCR I contacted the ...

im curious whats the motivation to replace asr1004 with ccr1072?? Oh, it's quite simple. ASR was quite pricey when we were purchasing it in the first place. And now we're about to hit the 10G limit, which means another pricey upgrade. If the ccr1072 experiment works out, I'd be happy to sell our AS...

Thanks IPANetEngineer, I did read your blog regarding mikrotik stress-test. Probably your 80G bw post was the reason we decided to buy a 1072 in the first place. So thanks for your efforts, I hope we will enjoy replacing our Cisco ASR1004 with MT1072 once all the testing is over. Btw, why exactly do...

Thanks, pukkita

And is there a way to dynamically change data rate limit for a connection that got a dynamic queue based on RADIUS attribute?

Hi, I want to try CCR1072 as a pppoe server with shaping for ~10k simultaneous connections. There's roughly 10 different possible data rates that a client might get (e.g. 2Mb/s, 20Mb/s, 40Mb/s, 60Mb/s, 100Mb/s) After reading the Wiki I'm still confused about what kind of shaping to implement for lar...
