Hi,

The CRS354-48P we installed 7 days ago in our office for prod/testing seems to be stable with 6.48.1. We have no rev2 on this one. Running like a charm with a bonding, VLAN, trunk and access ports, DHCP option 82.
No QSFP used indeed.

Best Regards,
Julien

I've replaced the CCR2004 with a CCR1072 and it's running like a charm !

I hope that Mikrotik will soon consider making a premium hardware product line in parallel of the cheap hardware race !
RouterOS has so much potential, it's a shame that this software has no more premium rock solid hardware...

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...

abyss

Hi,
Our CCR2004 has rebooted without proper shutdown during night with 6.47.8. Not fixed yet. It's not a power problem because this device is in a rack with dual power circuit.
Reboot happens after 3.8 days of running time the 04 December

Hi,

Any news about this topic ? Tried many settings but dude continues to disconnect/reconnect to devices.

Hi, WanOs has only gigabit solutions, seems to be too small... We have connected the fiber link directly on the 1072 and directly a server on each side, same result around 619 mbps.

It's routed, but the link was always on the CRS317 ad CRS326 attched to the 1072, this window problem impact the routed traffic on them. We made the crossing VLAN for tests. We will try to mount the link on the CCR1072 directly and see if routed traffic is subject to the same performance problem or ...

Even is we plug this link on both CCR1072 and do routing or VPLS you think so ?

Hi, Thanks for your replies, The link was on the CRS317 before, with another layer 2 provider with same ping time due to distance.

Thanks for your comment, I'm not a native english speaker as you can read

If you talk about brand, I'm asking if it's a good idea to make a test with another switch brand. To be sure that's the problem come from a configuration or a CRS cascade.

Sorry.

Hi, Is Capsman going the way of stacking Mikrotik routers ? It would be a great feature the ability to concatenate multiple Mikrotik devices in one.

Hi, Controlling clients with access list prevents bad signal clients and low bandwidth. The biggest difference with seamless roaming, multiple AP and unifi is the that clients see only 1 AP and 1 mac-address.

abyss

After Doing some tests:

Better configuration seems to be:

Disconnect timeout 00:00:15
