Hello,

Is there any news or draft spec on the hardware of the CRS317-1G-16S+RM and release date?

Will the CRS317 support VLAN ACL? and will it be suitable for use as a core switch in a high throughput network running a RIP, VRRP, bridge?

Thanks.

Any update?

Waiting for one of the >2 SFP+ port switches myself.... I'd just like a price and a timeframe.

It will be nice, if it would be available within the next few weeks/monhs, i.e. Q2/Q3 2017

It would be great if we could get any info at all on this product. Hardware specs, price, date for getting to market. PLEASE!!! something any data.

Can I use 1.25G SFP transceivers with CRS317-1G-16S + RM?
Do SFP+ ports support 10G ONLY?

It works also with 1.25G modules

Can you do interface bonding with the CRS317?

In SwOS the link aggregation on CRS317 is supported at hardware level. In RouterOS it will become available in future.

Great, thanks. Any information on the packet buffer size? We often have problems with packet loss to 1Gb hosts.

Does anyone know if this switch supports RoCE v2 or Priority Flow Control?

So if the 98DX8216 ASIC supports PFC/RoCE, does SwOS?

I tried it with 1.25G modules. It does detect them, but does not get link.

If I plug the same module out of the 317 and plug it into a 226 (sfp-sfpplus1 port), it works perfectly. ROS 3.41rc32.

I bought 3 crs317, but it turns out that I can't configure vlan like on crs212.
I was conected via ethernet, but when i was trying to install a new package, the transmission speed reached 20kbps (max),
system.npk I uploaded probably 5 times before all went through.
Tested on 2 crs, with different cables

Hi ,, I ran into the same problems. The way of doing the configuration has changed.

Read this for 6.40.1 and up: https://wiki.mikrotik.com/wiki/Manual:I ... N_examples
Beware .. VLANs will be done in CPU, not in hardware doing it this way.

Hardware offloading is not implemented until the latest release candidate. I've installed 6.41.rc32 on mine and it works fully with Hardware Offloading now.
Read:
https://wiki.mikrotik.com/wiki/Manual:I ... _Filtering
https://wiki.mikrotik.com/wiki/Manual:S ... Offloading

Also .. if you configured it as above under 6.40.1 and then go to 6.41rc32 or later, you will have to remove the bridge-partners and re-add them (so reconfigure your switch basically from scratch) to be able to enable hardware offloading.

If works though, afterwards. And I quite like the new way of configuring the VLans. Much tidier.

Did you try disabling auto-negotiation and forcing link speed to 1G on both sides?

I would have expected the same behaviour from either switches, so no, I didn't do that.

I've tried that now and that solves the problem. Is there any explanation to that behavior ?

My CRS317 is almost silent when used below 40℃. It can work with DACs from Cisco and Dell. But I’m using more cost-effective FS SFP-10G-DAC on it. Turns out it is fully compatible and works perfectly. BTW, I was also wondering if I could use this CRS317 as core switch as I planned for a upgrade in my server room to handle the increasing data traffic.

Hi,

I need to use the CRS317-1G-16S+RM in a TELCO environment (-48VDC).
What about the "internal voltage" behind the two bulit in AC power supplies? 24VDC, 48VDC?
Is it possible to replace the internal AC power supply with eg. https://shop.meconet.de/Stromversorgung ... 17098.html and feed it with NEGATIVE 48VDC? Or positive 48VDC with a DC/DC converter?

The same question is generally for the CCR1009 and CCR1036....

Thomas

We are developing new products with -48 V so I wanted to ask, for your specific environment. In a DUAL PSU device, would you prefer both PSU to be -48 V or rather have one -48 V and the other AC 110/220 V ?

Hi normis,

if we place this unit into a street cabinet together with a DSLAM, one PSU with -48VDC and one with 230VAC would be fine.
At our CO we have -48VDC and 230VAC both redundant.
I would prefer modular PSUs. So just give the unit two free slots and variants of PSUs, so we have ONE hardware that fits everywhere.

Do you have an answer to my question above?

Regards
Thomas

Modular PSUs like on the 72-core CCR definatly would be better.

And then offer a -48V and a 220V version. That way, you can swap as you need.

And definatly dual PSU, both modular.

/M

Definitely modular PS units. In most cases, we will do all AC or all DC.

With Cisco, you can't mix and match. It doesn't really matter anyhow. But yes ... modular is a must. And redundancy also.

/M

+1 to modular PSU.

Redundancy is pointless if you cannot swap out the dead PSU without downtime...

In many cases, the SFP optical module can be inserted into the SFP +. But there is a general confusion about the compatibility of them both. They may not work in all circumstances. The SFP optical module can operate in the SFP + slot whereas the reverse is not true. If you insert an SFP module on an SFP + port, the speed is brought down to 1G instead of 10G.
The port may lock itself to 1G speed and you may need to reprogram it for upgrading speed. SFP + ports usually can’t sustain speeds below 1G. Thus we can’t use 100Base modules on SFP+ ports.

If you are in a telco office, there will be an A and B -48dc feed. So you would want two -48 supplies. Most telcos I have seen do not have 110 at the rack.

What are the latency specs? They don't not seem to be published on official specs page..

I have a CRS317 and the bandwidth control is not working. I made the ACL per port controlling but the traffic goes much more on the client. I do not know what it can be since HITs normally count in the ACL. Version 2.7 swos

There you go

i want to know million packets per seconds.

i want to know million packets per seconds.

You can't get that data, it's confidential.

Perhaps data about thousands packets per second would do? It's there, in colums kpps (kilo=1000 packets per second). You might be able to calculate Mpps from that.
