Very happy to see v7 finally coming together.

What's the kernel version?

as a workaround, ECMP works perfectly with OSPF instead of BGP, assuming your setup allows for it. alternatively, the tip provided by heribertos using routing filters forcing the "Next-Hop-in" to your desired multipath gateways might work, though you'll lose the fully dynamic aspect of BGP by essent...

i've required this feature several times already. i understand i could use a route reflector to give all my routes back to me and put then with a different routing mark, but that would require a separate router with extra physical connections, which makes no sense as it should be very easy to do a c...

still cant change any user names.
introduced in 6.43.0

Don't know if it's already been mentioned, but I can no longer change the name of a user in /user
It's not only the default user, it applies even to newly created users.

I need to know this as well.

Feature Request: With the use of interface-lists, set customized permissions to which interfaces a user (and preferably also snmp community) can see or make changes to. Some of our clients like to have read access to our routers, but sometimes it's a router supplying more than one client and giving ...

Do you have connection tracking turned on? how big is your connection tracking table? I found previously that port scanning created many connections to port 445 filling up connection tracking table and causing CPU spikes. Not sure if this is exposed to the Internet or not and whether you are blocki...

Do you have any masquerade rules? What is your OSPF topology like, is there anything that would cause frequent LSA's like /32 routes for PPP tunnels? Also I am wondering about the bonding - fastpath apparently on works with bonded interfaces on receive, and apparently even then only since RouterOS ...

OK.. also, good idea to check for certain bad settings that can kill your performance, for instance turning on "Use IP firewall" in the bridge settings kills the CPU, good to identify whether there might be some issue like that.

Good one.
In my case it was already disabled in all routers.

Trying to experiment with IPFIX instead of NetFlow, my monitoring software reported flows from 1504215292 seconds ago and promptly discarded them. First I thought it was some misconfiguration but after trying to change back to NetFlow and seeing everything working fine, it ocurred to me... As it tur...

OK.. also BTW I think you misunderstand fastpath - fastpath is automatically active when it is enabled and you have no firewall rules. Fasttrack is kindof a 'fastpath-lite' where you can fastpath some traffic in situations where you need to have firewall rules and other such things. It is not as ef...

Can you paste your config with the hide sensitive option? What did you learn from the profiler? You should be able to see when a CPU is maxed what process is maxing out that CPU. I need to update RouterOS, the current version in that CCR doesn't support per-core profiling. Will do that later tonigh...

What volume of traffic are you pushing through these?

5Gbps tops, adding all interfaces.

We're trying to activate a new peering connection with a partnet but we're being denied because, according to them, our SNMP is answering requests on v3 and this can be abused for DDoS attacks. Here's the results with snmpwalk. [root@dnslookup ~]# snmpwalk -v1 -c public 10.112.194.2 Timeout: No Resp...

Hello. From checking the logs this might indeed be the problem (the current RouterOS version doesn't support this, I'm yet to update it). http://puu.sh/xoj8D/fd901a6b65.jpg Also, I noticed that disabling IP Flow in this CCR (1016) reduced CPU usage from ~20% to ~15%, while on another CCR (1072) enab...

We have several CCRs and noticed small levels of packet loss (anywhere from 0.3% upwards of 2%) whenever CPU utilization is above 5%. One thing we noticed is the only scenario the packet loss doesn't happen is when the CCR is using Fast Path for all its traffic. If Fast Path is disabled (firewall ru...

I'm trying to get both VLAN Trunking and Q-in-Q working at the same time but to no avail. I can do either one just fine, the problem is configuring both at the same time in the same CRS. I cannot find any documentations on how to get it done, the ones for them separately do not help much as the conf...

Winbox has a bug - in Windows 10 64-bit with Anniversary Update cannot click on buttons inside DialogBoxes. can confirm this bug, though i suspect it's a windows bug rather than winbox. dialog/confirmation boxes cannot be interacted with on windows 10 creators update. examples of such boxes are "do...

based on our own needs here, i'd like to especially have more ports in a single router (given the CPU can handle it). example 1 (medium thoughput, actual router, not CRS): 24 SFP 2 SFP+ example 2 (high throughput): 8 SFP 8 SFP+ example 3 (very high throughput): 8 SFP+ 4 QSFP in all three cases, both...

did a quick search and only found a very old thread.

Add OID for SFP-specific port information such as:

Rx Power
Wavelength
Link Length
Connector Type
Vendor Name
Vendor Part Number
Vendor Revision
Vendor Serial
Manufacturing Date.

Thanks!

I didn't test it under load but the queues at least seem to be working.
Another question, is it possible to only limit the /32 host at 25 Mb/s if the /24 network is under full load but if it's using 0 Mb/s let the /32 host use as much as he wants, up to the 100 Mb/s?

Good evening. I'm having trouble with a certain QoS configuration. I've looked online for the past couple of hours but could not find anything that addresses it. My needs are very simple: I have a bandwidth traffic for a certain network, lets say 100 Mb/s for 10.0.0.0/24 . Keeping that queue above, ...
