Ok, we will have to wait until after hours again to repeat this exercise. There is only 60 seconds between crashes so I need to try to capture everything fast, upload the stable version and downgrade. I will try and email support when done.

I upgraded a CCR from 6.13 to 6.21rc22 and the router started rebooting on its own every minute. Was able to see in the logs that the router rebooted itself due to a kernel error but had to quickly go back to a stable version (now 6.20) as it was a production router.

Anyone seen this on rc 22?

tenenbaum

Thank you. Would you consider this as a feature request?

I'm trying to copy only one ip firewall address list from one router to another, but ip firewall adress-list export does not allow me to export only a portion. It exports everything. Anyway to export only one list?

When we check the button 'Store on Disk' in the graphing option, I am wondering if there is some limit and auto clean up that the system does, so that the graphs don't consume the entire disk after awhile? Or do we need to do the clean up ourselves with some script. If we need to do it, how do we cl...

Was there any follow up to this? We are passing 300mbit on a CCR with 6.10 and getting many reports about SSL timing out, etc. No issues with our x86 routers on a different network passing the same amount.

tenenbaum

We are still having issues on CCR1016 with 6.7. It is MUCH worse than 6.5 ever was. The CCR on 6.7 is now regularly rebooting on the watchdog timer. Our config is very basic, 2 ports set to the default Gigabit/AUTO and ether4 set to 100Mbit/FDX. On 6.5 it is stable but the 100/FDX port will randoml...

3fixes for CCR Note that having other interface queue than only-hardware-queue dramatically reduces performace, so should be avoided if possible; We are still having issues on CCR1016 with 6.7. It is MUCH worse than 6.5 ever was. Have you tried to disable the LCD. I know it's strange but ours has b...

tenenbaum

Actually this happens to us on the x86 RouterMax. We run the latest firmware and ever since we got these, and if you change an IP or disconnect a device and connect it again, it won't re-establish layer 3 and only a reboot will fix it. OSPF can take a few minutes to re-distribute. The port flapping ...

tenenbaum

Honzam, We only have CC on our backbone so I'm not sure I should test with 6.7 I am planning on taking one of the back-hauls down, allowing the primary to go over 300Mbit and see if it flaps with the LCD off. Problem is we can only "test" during peak hours as off hours the traffic is below...

tenenbaum

honzam,

I will see if I can put my hands on 6.7 and test it. We are seeing less flapping when LCD is disabled.

Using firmware 6.6 on a CC and it's still flapping. We disabled LCD and SNMP and it's a bit better. What we noticed is that these conditions will cause flaps: 1. Over 20,000 pps per interface 2. Over 300mbit per interface 3. SNMP 4. OSPF changes It's almost like there is a capacity limit that is eit...

tenenbaum

Same here. As soon as we cross 300mbit, it starts to flap non stop. Does not happen on x86 platform. Using 6.6 and it is worse than 6.5.

We have an RB493G router with 6.2 on it right now. Somewhere along the road something happened to it and anytime we bring up the DHCP server window, winbox crashes. It started in 5.x and we kept upgrading the firmware thinking it might go away, but no help. We can access the DHCP server settings jus...

tenenbaum

By the way normis, at every client now we have a RB, usually 750UP behind the wireless CPE and in-front of their router. We noticed that the speed test results the customers get at speedtest.net and speakeasy, are inline with the same speed tests we get with the RBs when TCP is checked. So while the...

tenenbaum

Thank you. Actually we test from end users browsers, routers, CPEs, demarcation MT board, single connection multiple connections, you name it, TCP always gets lower throughput (even on a cloud core connected directly to a gig fiber circuit or a Mac behind it with Iperf.) What is interesting that if ...

tenenbaum

I was getting similar results even with high end equipment like core cloud and power routers... what we found is that the problem was in the wireless legs. I am not sure if I am correct on this, but I think that the UDP packet does not need to transmit back while the TCP does... We were getting UDP ...

tenenbaum

So we got a couple of CCR1036-12G-4S and running latest firmware 6.1 Connecting with two different computer with shielded cables to all Ethernet interfaces, we are getting <1ms latency and then every 10 or 15 packets the latency jumps to 100ms, 200ms, etc. No errors on the interfaces Tested with the...

tenenbaum

Well, our situation is slightly different. We are using a board in bridge mode infront of every customers.

So while we can capture the customer now and redirect them to the /graphs of the bridge ahead of their network, it's not easy to mask the IP and make it friendly.

tenenbaum

Is there a way to auto redirect users that go to the router local address, to the /graphs directory? And further is there a way to customize the look of that page?

Ofer

tenenbaum

andriys and network pro, I thought our system was tagging things properly but I found out that the packets coming out of the pbx system were losing their tags in the router (I am still researching why.) So I made the router re-tag in postrouting and sure enough that addressed the issue. Mid day and ...

tenenbaum

interesting situation - this is a good question so you have a radio network with high pps rates ? If you test the same setup on Gigabit Ethernet what would be the result ? Thank you for the reply. The problem is increased number of packets during the work day with low bandwidth utilization. We are ...

tenenbaum

NetworkPro, Thank you for your input here and the article. Let me try and explain why I think LLQ is needed, and please correct me if I'm wrong. We have an extensive network of relays that connects residential and business customers. During the day we see only about 50% utilization of our network, s...

tenenbaum

I vote for LLQ

tenenbaum

Thank you RomelSan. However, your answer and example does not answer my priority question.

Ofer

tenenbaum

Anyone?

tenenbaum

I know it's probably so obvious but I looked around and could not find the answer. Let's say I have 10 PCQ queues. When I setup queue priority, is the priority considered within the tree or only within children of a parent or both? In other words, let's say I had the following queues: master priorit...

tenenbaum

winagain, that would be nice but it's not working like that.

Ofer

tenenbaum

I agree. We just started using the hotspot feature. We have a building where every user needs to get X amount of bandwidth for Y amount of devices. Problem is that while we allow the user to login with Y devices, the bandwidth the user is getting is X+X+X as many as Y is. So I agree with the origina...

tenenbaum

I have somewhat of a similar problem and hoping someone can help. When I create a limitation and set various rates, then I move to the next limitation and setup different rates, then open various limitations, some lose all their settings and display different values from different limitations. I tri...

I upgraded our router from 5.7 to 5.8 and now I get page not found at /userman

Help.

tenenbaum

Thank you for recent release and addressing a lot of issues we had with 5.6. A few months ago I asked if it would be possible to add back the ability to sort by port in the Torch. Back then I thought I was all by myself but now if I search on port sort, I see a lot more people complaining about the ...

tenenbaum

In version 4 the torch window had a separate column for dest and src ports. Since version 5 it is combined with the address. When you use torch to research connections, it is very hard to see what is going on because of that. Is it possible to add back the the two columns so that the ports can be di...

tenenbaum

I apologize if this is in the wrong place. In version 4.x the port had a separate column in Torch window. Now the port is merged with the src or dst IP. Any chance of allowing or giving the option to the user to have a separate column for the port in 5.x?
