In my experience coding the SFP(+) for different vendors is only done to get around vendor lock-in. I even have a few original Cisco FET-10G modules that won't even work in non-Nexus Cisco boxes, which work just fine in my CRS-309 and get recognized for what they are, 100m reach 10GBASE-SR.

mbovenka

In the CRS305 that port is connected to the switch chip. In the CRS304 it's connected to the CPU.

mbovenka

Management-only ports are excluded from the count, as they aren’t meant for general-purpose I/O. Prior art: CRS312, with 4× combo ports, 8× 10GigE, and a 100M management port.

I have after my previous mail seen the block diagram. I guessed it would be something like that.

mbovenka

Why is the CRS304 not called the CRS305? It has 5 wired interfaces, just like the existing CRS305 does. And there are already two CRS326es, so that can't be the reason.

mbovenka

MT devices can be a bit picky when it comes to working with SFP modules ... I haven't had any problems with SFP(+) modules in my hardware (CCR1036, CRS305, CRS309, RB4011). TP-Link 1000BASE-BX-D BiDi, FS.com generic same, FS 10GBASE-SR generics or Cisco-coded, even Cisco FET-10G modules just work (...

mbovenka

No, neither is going to work. They are both SFP+ 10G modules (and to add insult to injury, the Cisco is a FibreChannel module, not an Ethernet one). The hAP ac only supports 1G SFPs. You probably need something like https://www.fs.com/de-en/products/11802.html?now_cid=89

CCR2004-16G-2S+?

$465,=, dual power and better BGP performance than the 1009.

mbovenka

MT should look at DPDK in my opinion: https://www.dpdk.org/

mbovenka

@mbovenka; Yeah, it should work unless routing to other subnets on the plant is needed.

Not even then, I think; it should act like a host and be able to accept a default gateway/route.

mbovenka

As the OP doesn't want any routing functions and just wants to have the box acting as a multihomed NTP server, isn't it enough to disable IP forwarding (/ip settings/ip forward=no)?

mbovenka

Yes, RouterOS uses source port 123, by their choice, when the NTP client is performing NTP requests (and so the response comes with destination port 123), but NTP servers don't care about the source port. Only about the destination port, of course, which must be 123. Perhaps MikroTik went this way ...

mbovenka

Are simplex transceivers only for singlemode long distance? Could I use them anyway with attenuators? If you get 10GBASE-BX-10 (10 km reach) modules you don't need attenuators, for them max Tx & max Rx are both 0.5 dBm so the transmitter won't overdrive the receiver even with a very short cable.

mbovenka

Personally I'd keep a proper router/firewall as edge device of my LAN. For one that's needed if NAT is required (I'm pretty sure NAT can't be offloaded to hardware). Yes, it can: https://help.mikrotik.com/docs/display/ROS/L3+Hardware+Offloading#L3HardwareOffloading-L3HWFeatureSupport I still intend...

mbovenka

I cannot imagine a situation where you would usefully have a port as an untagged member of multiple VLANs, which is a flexibility that this config provides. Most other manufacturers do not even allow such a configuration. I can't even imagine how such a config would work in practice. Destination IP...

I use a E3372h-320 on my CCR1036 that works like that as well. It only works in v7 (as documented in 'Peripherals').

mbovenka

Except crashing, that you mentioned? That's no big deal?

Not neccessarily. The OP talks about a home setup; the box randomly rebooting say, once a month may well be acceptable if it buys him the ability to use the 2.4Ghz band when needed.

mbovenka

My stick is a Huawei E3372 as well, the type that functions as a NAT router ("Config-less LTE interface" it says in the supported models list). It was really stable on v6 but on v7 (with the RB5009) there have been hickups. I use a E3372h-320 on my CCR1036 that works like that as well. It...

and the forced settings disables auto-negotiation. But it shouldn't.. The remote end should still autodetect what the local side it forced to. But it doesn't, at least not in my experience.

mbovenka

it's just autonegotiation or forced speed/duplex (which needs to be half-duplex if the other side has auto-negotiation and is not forced to full-duplex, otherwise we get a duplex mismatch with high packet loss) Why?

You're aware that the RB3011 has an SFP port, not an SFP+ one? You can use an SFP in an SFP+ cage, but not vice versa.

mbovenka

What about those users mistakenly buying the CCR1036 R1 ? i experienced 4 times of PSU failure since 2018, average 1.5 years a blow.

I very much doubt whether there are still r1's in stock anywhere. I already got an r2 when I ordered mine 4.5 years ago.

mbovenka

BGP convergence will be faster on the 2004 (more single-core performance). For forwarding performance the 1036 wins.

So it depends on what's important to you.

mbovenka

I think squeezing all that in and have it passively cooled to boot is going to be a tall order. Especially if you want PoE to boot. I wouldn't count on something like that appearing any time soon.

I stand corrected. Doesn't have the grunt to use as a daily driver desktop, but as a dedicated router it would be great.

mbovenka

Hackers knocking on your door. When I still ran L2TP VPNs I saw those all the time.

mbovenka

Defaults are not applied by updates. Once you have made a setting it will be saved and restored at reboot, you need to change it to 30 seconds yourself when you want that. New installations will get the new default. Interesting. That's not what I am used to (working mostly with the Big C @$dayjob)....

mbovenka

If set US, mikrotik say 5400Mhz no supported channels

Set the frequency to 5400 and the mode to 'superchannel'. Assuming the L11UG-5HaxD radios can physically do 5400 MHz, that should work: https://help.mikrotik.com/docs/display/ ... properties

mbovenka

Veeam will take backup over this connection. As far as I understand from your description, the speed will not exceed 1g+ as it will create a single connection in veeam.

Yes. Unless Veeam has a way to use multiple TCP connections for a single host-backup, that is what will happen.

Balancing-rr is the only bonding method that sends packets from the same connection across different interfaces in the bond.

mbovenka

You should have bought something else. CRSes are switches first, not routers, even if they can do routing. With the advent of L3 hardware offload they can route at wirespeed, but not all can also do L3 offload for NAT and firewalling, and the CRS310 can't . Looking at the test results , 500M is abou...

With L3 offload it will. The CRS309 is the cheapest switch that will do full L3 HW offload (with FW/NAT handling). That's why I got it to play with; for now my CCR1036 does a good job

P.S: also why would you use another router, if this one can do everything?

The -325 is only supported on ARM CPUs (https://help.mikrotik.com/docs/display/ROS/Peripherals). Your hEX S has a MIPS CPU.

Does take a bit of digging, and I have been bitten by it when using a 1000BASE-BX-U SFP in my CCR1036.

mbovenka

I don't know why it doesn't autonegotiate, but it's in the docs that you need to fix the speed & duplex when using an optical SFP in an SFP+ cage, and autoneg won't work. A DAC isn't optical of course, but you are effectively trying to do the same thing.

mbovenka

Looks to me it should work. Have you tried setting speed & duplex to 1000/Full instead of Auto? I needed to do that when using an SFP in an CCR1036 SFP+ cage.

mbovenka

....those are sites that you only should touch with a very long set of pliers! The best is to find ASAP alternatives for them or just go back to before they existed.

Which is fine for your own little network, but of course not really an option for those that have actual clients to support.

mbovenka

It ought to work in any CRS3xx with Q+ (40G) or XQ (40/100G) ports. Whether it actually does, no idea, unless someone tries or MT chimes in about it.

Yes, pretty much. Technically, for the network definitions in your DHCP server config you could use any value for last octet, because ROS is smart enough to compute the network from the address and the netmask.

mbovenka

You could put the ports in a bridge, but note that the 1036 does not have a switch chip, so everything is done by the CPU.

mbovenka

Please confirm if it is true that the CRR1072 will be discontinued after this year

Given that the TILE CPUs are no longer made by NVidia (like @chechito already mentioned), and the CRS1036 is already discontinued, I would be almost surprised if it wasn't.

That layer 3 performance, at least from the brochure, is something I would not even use at home.

Looking at the test results for the CRS309, it seems that it's nowhere near capable of supporting 10Gbps with firewall rules in effect.

It is with L3 hardware offload. The CRS309 can do full L3 offload, including firewalling.

mbovenka

I use a Huawei E3372H-320 with my CCR1036 for exactly this purpose (backup). Needs ROS7 to work.

mbovenka

Your Huawei 3272 will probably work. I'm using a 3272h-320 that presents itself as an LTE interface with a NAT router and DHCP server 'at the other end' so to speak, on 7.1 and it works fine. Actually, I had to upgrade to ROS7 to get it to work to begin with, it wouldn't work with ROS6.

mbovenka

If you can pull cat6e (or cat7) UTP cables, then you could pull FO cables as well. And optical SFP modules generally don't suffer from the excessive heat generation problem.

mbovenka

SFPs in an SFP+ (such as the 4011 has) cage need fixed speed & duplex, as you found out. That is documented somewhere, but it's somewhat hidden. I've been bitten by that too. The 2011 has an SFP cage, which is why that worked with AUTO.

mbovenka

if you want no heat you have to use 1G Base T module

Or use 10GBASE-SX and multimode fiber. Cheaper, too.

mbovenka

I was looking at that CRS312-4C+8XG-RM, but I am guessing that it doesn't handle a 10 gig WAN port (Cause I tried with the 305) The CRS312 will do NAT in hardware, if that's what you mean by 'WAN port'. As you found out, the 305 will not. https://help.mikrotik.com/docs/display/ROS/L3+Hardware+Offlo...

I wasn't aware the S-85DLC05D could do 100M at all, and I can't find anything about it either. Same for the S-31DLC20D. So count your blessings if it works at all, I daresay. Where did you read that either SFP could do 100M?

mbovenka

If you want to run POE on all ports, probably. Note that it isn't at all unusual to ship a POE-capable box with a default PSU that won't power all ports.

mbovenka

Or you want to use an MBIM-driven 4G USB stick. I had to upgrade my CCR1036 to 7.x to get mine to work.

mbovenka

By adding the drivers for the Intel i225-V network chips for the x86 and CHR versions of RouterOS.

x86 ROS is dead or dying, and CHR leaves the hardware support to the hypervisor, as it should. I suggest using CHR.

Does sound like a transceiver issue. I use an S+RJ10 in my CRS305 to connect to my PC, and it autonegotiates and shows 2.5G just fine.

Thank you for your detailed answer! Thus, if we use the S+85DLC03D SFP+ modules instead of the Q+85MP01D ones, we'll have 10G connectivity between the "low speed" CCR2216 ports and the respective "low speed" ports of the CRS354. Otherwise, as we have only 2x100G spare ports on t...

mbovenka

So the same SFP+(10G) port will fit into SFP28925G) ports as well? and if that is Yes
Then i will assume QSFP+(40G) will also fit into QSFP28(100G) also?

Yes to both, I think, but I'm not 100% sure on the latter.

mbovenka

S+RJ10 should work in the SFP28 cages.

mbovenka

Will this router be fast enough to handle some modest routing, including IP masquerading and some basic filter rules at 1Gbps through the WAN port? No. Not by a long shot. A rough estimate of real-world performance of a given MT router is the '25 IP filter rules' test results with 512 byte packets....

mbovenka

Hap ac is a bit hybrid. It can easily be used for both. Quite so. I I'm using one as an AP, but it's a reasonably capable router if you want to use it as such.

However, CRS305 has potential to surpass that mark by large margin, ROSv7 enables L3 HW offloading which means that in optimal scenario CRS305 will route traffic wirespeed (but only between SFP+ interfaces, ethernet port will always bog CPU).

A good question but the BT engineer I spoke to didn't offer that as a option. Esp. as whilst it's a 1G fibre link, the client has only licensed 300Mbps.

Makes no difference technically. It's probably just a question of "you didn't order it terminated on copper, so you get fiber".

mbovenka

Never really worked with fibre but I think I need a short fibre cable and an article I found suggested I needed a SingleMode LC SFP transceiver. Does this sound right? I think you can use SFP in SFP+ but not the other way around. Looking at the color of the SFP clasp (black), it's probably multimod...

I'm curious if there will be any 48V models of the CRS2004, it will they be AC-only? Preferable fanless models as well.

RB911: Series 9 board, 1 10/100 Ethernet port, 1 wireless interface
RB912G: Series 9 board, 1 10/100/1000 Ethernet port, (potentially) 2 wireless interfaces

That's how the board naming comes out. How many wireless interfaces does the 912 actually have? If 1, that may be why it shows as a 911 in ROS.

Something else that I'm thinging It may didn't work because the setting were applied only on my side.

Quite possible. If the other end is a similar setup, it may well have to be done there as well.

Thanks. I have tried this bit it didn't work. The transceiver that the ISP gave me is quite old so I'm thinking of buying a new one and try again.

Probably best, those 1G SFPs aren't very expensive. I can vouch for it working with multiple 1000BASE-BX-U BiDi SFPs in my CCR1036-8G-2S+.

mbovenka

The 317 with L3 HW offload will do the trick for IPv4, but offload has as yet no support for IPv6.

mbovenka

You can use the 1000BASET port on the 305 to uplink to your gigabit switch. ROS makes no difference between the ports.

If you want 10G as uplink you'll need something like a 326, yes.

I'm guessing CRS326-24S+2Q+RM?

mbovenka

Assuming you need a router, you need something with an SFP+ cage and use a copper SFP+ like the S+RJ10 in it. Cheapest option is a RB4011, cheapest with multiple ports is a CCR2004.

Switches with 10G copper ports will also do 2.5G.

Nonetheless, you are right that CRS317 or CRS309 is a better choice (than CRS312/326) for hardware-accelerated stateful firewall, but for a different reason: CRS317 and CRS309 have twice larger hardware memory .

Or arguably CRS317 if you count it as mediocre router. Which is quite dated performance level.

On a PC does it show up as a storage USB drive with software in? If it does, you need to reflash it to 'Stick' mode which I found impossible.

How does the hAP AC compare to the hAP AC2 ? Better WiFi, slower CPU.

Interesting as I have mostly default configuration out of the box. Only changed IP for LAN interfaces and done. Did you do anything to enable HW Offload on yours? No, nothing. I use mine as a plain wired switch & AP, so all interfaces in a single bridge, STP disabled. That's pretty much it.

mkx I disagree with your statement. I have an RB4011 with no VLANs (all ports on the bridge interface only) that I support for a client that doesn't get HW Offload even with no VLANs: So I don't expect wired speeds between LAN ports inside of the RB4011.

Is it possible to flash to the standard firmware on the device wiping it completely without being able to actually get into the web interface of the device?

You could try a netinstall.

mbovenka

OK, I stand corrected, if that's your experience. But just saying 'no, it only has 4 cores' isn't very helpful...

mbovenka

Yes, and those 4 cores are a *LOT* more powerful than the ones in the CCR1009. The CCR2004 has close to 3 times the forwarding performance of the 1009.

That may not entirely map into a 3 times lowering of the CPU load of the OP, but the CCR2004 will no doubt be a step up.

mbovenka

If it still appears in Winbox, you could try connecting through the MAC address. If not, a netinstall with an older ROS version might indeed fix it.
