RATE SELECT is specific pin of the SFP slot interface that can be used to change operating rate of the SFP module. Low/High are actual voltage levels Mikrotik sets this pin to. If it actually does anything and what it does depends on the specific SFP. So check your SFP module specification... What ...

It would help if you post your config. Firewall rules can easily block them from establishing.

In the computer you're using to access the VPN, you can disable use of the VPN for default route in the VPN settings. I am trying it on PC with Debian and Android Mobile phone connected to AP in bridge mode. If the computer is initiating the vpn connection, then I believe you will need to figure ou...

We've reported it to Mikrotik on multiple occasions an they've been able to replicate it. Unfortunately now we have all the CCR2004's out of production so we cannot provide any further production testing - The risk was too high leaving it in the network. This is where I am at on the subject as well...

No solution yet. Even downgrading to 6.45.8 anyone?! I've been running the 6.47 variant in my 3011s and ccr1009s, without port flapping issues. They have uptime since I upgraded to either 6.47.7 or 6.47.8, so 45-60 days ago. All are running ospf and mpls /vpls. I've migrated to the later versions o...

mikeeg02

Just opened and supout sent, i believe it is something to do with ospf and or mpls. I have other 2004 routers but they don't reboot that often, some have uptime as much as 20 days. these instead restart every 7-8 hours (OSPF + MPLS, no firewall, mix of 10G 1G interfaces) Same here, 6..48 and a lot ...

mikeeg02

Yes, they suggested custom firmware and wanted serial out information. Though the response was unfortunately after I pulled the unit from service. This unit was located about two hours from my office. A little too far to gamble. I had two in a redundant setup that were ten minutes from my office, w...

mikeeg02

I havent tried 6.48, but the thread from 6.48 doesnt look stable at all. I pulled mine last 2004 from service for now until they are stable. I think I have about 6 of the dang things. They suggested custom firmware for them, but I cant let it keep running like that. I will have to setup a separate ...

Sent another one in. SUP-37419 (new) SUP-35544 (yours) SUP-30924 (my previous) Yeah and sent in some more too - one asking if 6.48 does in fact solve anything more but got a wierd response so I've asked for clarification.

Hi,

We had 2 reboots on 6.47.8 in the last 24 hours. Seems they last longer but still reboots.

/Mikael

Mine was going strong until you said that, it died 2.5 hours ago lol, time to pull it I suppose. Has anyone had better success 6.46 long term versions?

Mine is running an apartment complex providing internet to tenants. Nothing fancy. Just a few VLANs, NAT and firewall rules. Peak traffic is about 500mbps. What types of sfp's is yours using ?

mikeeg02

We've had one reboot since being on 6.47.8

Device was installed on the 12th this month and rebooted on the 14th :(

Do you have any logging running? CPU performance, etc? Traffic?

What sfp's are you using?

mikeeg02

Hi, Are any of you experiencing reboots still? We actually havent had any on 6.47.8 yet and the interfaces going down could have been from an RJ45 sfp plug which does makes me wonder about power in the sfp cages on the 2004, but it wasent even connected to anything so was easy to remove. /Mikael I ...

Thanks for the updates and fix!

Ive noticed lately as soon as I am logged in, the post button goes away for the software feedback in the announcements section. Anyone know whats going on? At first I thought it was my account, but I noticed that nobody has replied to the new 6.48RC thread, so maybe nobody else can either?

mikeeg02

Why do you keep only guaranteeing 10kb/s on these two queues anyways?

Is that all thats truly desired to have gauranteed?

Or maybe the whole goal is to learn service based limiting?

mikeeg02

I believe I have found how created my problem. I believe it was related to queue size. I was doing testing previously with larger queue sizes and higher bandwidth affects on processor performance and such. I outsmarted myself. My apologies.

mikeeg02

Interestingly enough. I was able to fully duplicate what the OP complained about this morning before I left the house. Now that Ive tested with the sub-parent, and returned to a queue more like described above, it works as it should. I know 6.47 does operate differently than 6.47.8 does. I've been ...

mikeeg02

With 6.47.8 and what hardware? 6.48 beta58, RB4011 wifi model, fasttrack disabled (of course) I don't think 6.47.8 should behave any differently. Interestingly enough. I was able to fully duplicate what the OP complained about this morning before I left the house. Now that Ive tested with the sub-p...

Without the intermediate queue on this release, the prioritized traffic it not queued/dropped/limited at properly. CIR works as intended, but the max-limit is the problem.

mikeeg02

Regarding prioritizing the upload direction, the connection-mark value is common for both directions of a connection. So you can translate the same connection-mark to a packet-mark e.g. depending on in-interface . But if the root parents of queues are interfaces, you can use the same packet-mark fo...

mikeeg02

I believe adjusting bucket size is where you will find your answer. I still have my test setup together. I can try to verify this evening.

Hi again, Today we again experienced a drop of interfaces on a 2004. The drop this time was not all the interfaces, but still all ospf was lost. The other 2004s we are running in test has less traffic and no problems, but one thing I realized is that we are using an SFP28 (DAC Cable) port and that ...

mikeeg02

If you feel like it then please mail Mikrotik support and reference SUP-35544 which is the ticket we have with this behavior. /M Ill have to put them back in service to do that lol. Ive since replaced them. I will have to try them and either with the older version you started with, or wait for a ne...

Hi, We havent seen any reboots in 6.47.8 but one 2004 dropped and reconnected all intefaces same second.

How long was 6.47.4 stable for you? I went right from 6.47 -> 6.47.7, then 6.47.8 and experienced the reboots in all. The longest uptime I saw was 14 or so days. I did NOT upgrade the routerboard firmware yet. I have gone ahead and ordered a different CCR model to replace the 2004. I think my longe...

What version were you on previously?

mikeeg02

Thats what I was afraid of. Were you able to log into it shortly before it rebooted? Or do you keep cpu statistics? If so were they higher than normal before reboot? Yes, of course, nothing really special. It's not related to trafic, because it happens during night when it's much lower. CCR2004_Upt...

mikeeg02

Hi this seems to have been fixed in latest stable - 6.47.8 Thanks for the update, but with the old version it would last up to ~20 some days before it would quit. Sometimes as quick as 8 or so.I do hope they figure it out soon, I have about 10 of these now that will hold paper down, until they are ...

mikeeg02

I have two 2004s (and a few spares on the shelf), which are neighbors to each other in a small (mid 20s) mpls network, not a lot of throughput, not a lot of firewall rules(typical usage ~1%). Started with 6.47, tried 6.47.7 (which was better) but every so often they would just reboot. And typically ...

mikeeg02

Don't know if that is related to this particular update, but RB3011 couldn't boot anymore after updating from 6.47.6, being restarted every time after "Starting services" stage. I've tried NetInstall to 6.47.8 and 6.47.7 without and with config wipe — no success. Long story short — I've r...

mikeeg02

That makes sense, and now that I know the secret to making the non chr routers properly utilize EXP/COS (as of your comments last night) I was thinking adding the second router as a P router would do as you said above. I havent tested the loss of QOS with php using implicit-null, but in the manual ...

mikeeg02

But I cant seem to queue the packets that originate from the router. Yes, this is not possible, unfortunately. The issue is that ingress-priority is only set automatically when the packet first arrives at the router, and you can only match ingress-priority in bridge filter rules (not priority). Any...

mikeeg02

Hi, Yes, we experienced this problem long ago. This works fine with CHR but not with any hardware routers - if you are running any hardware router and not CHR, it ends up being COS 0 after the second router. The only workaround we found was to add a single port bridge on the second router, with the...

Currently running 6.47.7 **Updated to hopefully make things a little clearer.** Ive been trying to track down an issue I have been having with priorities, and believe I have narrowed it down, but cannot figure out why its happening and need some advice.

Can you post details of the config? Heres a dev router. Effectively everything that comes in ether5 is being packet marked and priority set before it goes into the vpls tunnel that starts here.

The licensed links are all ~150 mb/s. The voice traffic is low, but all sites get the traffic at the same time. Each of the vpls tunnels should be capable of 10mb/s. The big thing is latency.

I guess we read that page differently. When I read it, they have listed that the 2004 is compatible with 1G and 10G sfp modules (which if memory serves me right sfp's all are 1G or better).

What is a stable/reliable trap manager then?

I've been using the dude because its on standalone hardware, not associated with a computer. And it will poll snmp traps, just not work as a manager where it can just accept them.

I have a couple of pretty extensively setup snmp monitoring systems using a few mikrotik routers. I have snmp polling setup, but the one thing I cant seem to figure out, is how to make the dude act as a "trap manager" where it reacts when a snmp message from a device is sent to it (outside...

The VPLS MTU is the size of the MTU you want to hand off to your customer. The interface MTU should be set to accommodate the overhead of VPLS.
