Hello, We have sometimes hundreds / thousands mac addresses on WAN public interface that's not related to our gateway addresses, like 74.125.136.188, 92.62.130.180, 217.73.200.219, but mac address is same like our gateway. We need only one mac address on wan interface (only gateway mac). If we disab...

You are not only one people who need this feature

mindaugasr

I think You without Mikrotik RouterOS support of gepon does not have any possibility to implement this feature.

mindaugasr

Hello,
On this forum is several topics about olt/onu implementation. Mikrotik not confirmed that they work in this direction.
I think in near future we does not see this product line.
Regards

mindaugasr

Mikrotik, is any plan to release 12sfp 2 sfp+ with 36 core cpu?

mindaugasr

This solution can bring mikrotik to more advanced level like zte, huwaei
i agree this is fantastic feature!
We need to hear mikrotik verdict on pon solution on routeros

mindaugasr

Maybe mikrotik staff have some comments about OLT implementation on routerOS?

mindaugasr

Would be nice to see OLT on mikrotik aprox 1000usd solution!

mindaugasr

Do you are in same subnet with switch defaul IP?

mindaugasr

sergejs,
Can You tell me when will be fixed snmp bug? We have same problem as NAB
Traffic graphs in cacti is not correctly displayed.

mindaugasr

If You said Your swich is smarter than smart, we definitely need one feature: IGMP snooping!

If You add this, we can implement all network tasks.

Thanks.

For that issue, we also do not receive any reply from mikrotik support.

It is an indoor switch and it is not meant to be grounded. Try grounding via one of the mounting holes, if you want to use it outdoors.

Thanks for reply kirshteins, maybe You can send some picture with grounding example. My mounting hole seems to be plastic

mindaugasr

Hello,
I searched over forum, manuals and so on, but cannot find how proper ground RB 250GS switch?
Can anyone direct me to valuable info?

Very thanks.

Hello,
Thanks for suggestion. Can you tell on 500 meter link i should use tdma-period-size: 1? or lower? To archyve best ping latency? Maybe someone have config with best latency and throuput on very short link with 5.0rc1 and nv2? Maybe some recommendation on short links?

Hello, We have p2p link, rbb 433 ah + r52n on both sides. We use 4.6 firmware with exe config (nstreme + hw retries 15 + wds) it works prety good, stable CCQ average 97-99% connection speeds 270/270 mbps real speeds also pretty goods.

Solaris, I installed debian OS on virtual cloud on it arpwatch, aprox 5minutes try ping broadcast my network, and arpwatch resolves all ip and mac bindings in network and report changes via email, that simple my workaround. Native function i agree would be better.

Best regards,
Mindaugas R.

mindaugasr

gustkiller, where You get rc2

?

mindaugasr

Yes we have workaround, but native function would be nice.

mindaugasr

I have same issue as Inox, pleas see my screenshot, i post topic aprox 2 weeks but no reply

mindaugasr

I think ARPWATCH (or other MAC changes information via email) would be very helpfull. Pleas mikrotik guys implement this

Thanks

Thanks, You solved my problem, and exactly understand :) But strange if i use transparent proxy then all thing works without connection-bytes=10000-0.

Hello, We have for example 192.168.1.0/24 network and for each client want to give 5 mbps traffic, but some traffic like p2p and udp must be 4 mbps, but total traffic from user sounds like max-limit cannot go more to 5mbps. It is ability using pcq queues type limit many ports speed but not overrun t...

mindaugasr

Thanks for reply,
But why priorities start work if we queue5 set max-limit to 6mbps, for one user this situation is what we need, but second user have limited queue5 to 6 mbps, then 80,81 port traffic queue is full and all users share 6mbps not 100mbps.

mindaugasr

Hello, We try to build PCQ type queues for our network, we for example 192.168.2.0/24 network and need for each user to give 6mbps download traffic and prioritize for example to port 80 (max 6mbit traffic) and 81 (max 5mbit traffic), 80 port with 1 priority, 81 port with 8 priority.

Does RouterOS or SWos based router or smart swich support IGMP snooping?
Thanks for reply.

Don't use WDS with 802.11n. Use vpls tunnel and all thing go very well.

mindaugasr

1. First PPTP is very slow because our link is aprox ~100mbps; We can't use this slow encrypted tunnel. 2.
