CRS317-1G-16S+RM as a "Core" switch
Wondering if anyone has had a decent experience using one these as a core switch. We have 6 various CRS-226 & CRS-326 24port switches in our shop that are currently all daisy chained together and are looking for a better alternative (i.e. feed each switch individually from the CRS317). We're flipping over to new Netgate firewalls next week, so I thought now might be a good time to make the change. Appreciate any input.Thanks.

Re: CRS317-1G-16S+RM as a "Core" switch
I have 10-12 crs317 set up as core switches for running around 280 crs226 and crs326 switches in my isp Network
They have been rock solid since the first day we implemented them (when they became available)
They are all connected with 10 gbic modules to the crs226/326 and performs very well as core switches running about 150vlans so far
CPU usage is very low and the switch is very responsive

Hey thanks for the reply Carsten. Received the CRS317 this morning and have been testing it. Looking good so far.
Re: CRS317-1G-16S+RM as a "Core" switch
then You should expect slow speed from 10G to 1G port on the same switch, like 300mbps

Still with newest beta? I see higher numbers.then You should expect slow speed from 10G to 1G port on the same switch, like 300mbps

I get around 960mbit up and Down from the crs326 with 6.44beta20 so no speed issues anymore
Re: CRS317-1G-16S+RM as a "Core" switch
Interesting. I will test this on Monday. I didn't really test line speed on the 1G ports, just general connectivity.
Re: CRS317-1G-16S+RM as a "Core" switch
crs326 too with s+rj10, without any visual improvement, i tested on every beta, now it's 6.44beta40, do you reset the switch or do something particular?I get around 960mbit up and Down from the crs326 with 6.44beta20 so no speed issues anymore

and that "fix" - *) crs3xx - improved data transmission between 10G and 1G ports;
is due to my 1 month discussion with MT's customer support, their last response is
but I don't see any change in crs326, slow as alwaysI would like to inform you that the latest RouterOS v6.44beta6 contains further packet buffer allocation improvements on CRS326 to fix 10G -> 1G performance problem. We have also restarted the work for the same fixes in SwOS.

Thats weird, because I have tested it on 8 different crs326 all running beta20 and it works perfect, traffic shaping also does work, however the rate settings are still weird.
and a crs326 if I want to set a user to 250/250M speed, I have to set ingress rate at 400M and Egress Rate at 250M
On a CRS226 I can set shaper rate to 250M and Ingress port policer at 250M and they will give the user 250/250
But I can live with the weird settings on the crs326 for now, key thing is that it is working, and giving full speed with out traffic shaping.
all my crs226/326 are connected with the crs317 via singlemode fiber, some running on WDM Modules, and some on regular modules

Re: CRS317-1G-16S+RM as a "Core" switch
May be a MTU/SFP problem? S+RJ10 does only 1504 byte packets and does not show parameters to the switch depending on version of module. Try other modules e.g. the S-RJ01. I ordered another vendor for testing to get larger MTU.crs326 too with s+rj10, without any visual improvement, i tested on every beta, now it's 6.44beta40, do you reset the switch or do something particular?I get around 960mbit up and Down from the crs326 with 6.44beta20 so no speed issues anymore
Re: CRS317-1G-16S+RM as a "Core" switch
When I see your discussion I realize there may be something wrong with my setup. The problem is I always test 10G to 1G speed with intel X550 (10Gbe) on both sides, when I plug the 1G port to ordinary 1G ethernet card, the speed comes back to normal. The weird part is the both X550 works perfectly fine on 10Gbe.Thats weird, because I have tested it on 8 different crs326 all running beta20 and it works perfect, traffic shaping also does work, however the rate settings are still weird.
