What type of SFP's are you using at both ends? Do they show up on the miktotik under the SFP option under the SFP interface?
Are you getting a link ? Send/Receive around the right way?

I've used a large number of different types of SFP's with mikrtik's and they don't seem to be fussy at all.

Hi there. I have a problem exactly the same as: http://forum.mikrotik.com/viewtopic.php?f=13&t=69858 My Set up 1) Mikrotik - Routed network with a /30 over the VLAN it and I can max our 100/50M connection 2) Miktotik - Run PPPoE over the VLAN and I get only about 50M/50M over the PPPoE Connectio...

I found what route marking didn't work properly after upgrading to V6.10 until I upgraded the Firmware (3.12) as well

There have been multiple discussions on the forums on the use of /127s with MikroTik. Its currently not supported, and as far as I remember, no support was promised. /31s for IPv4 are not supported either. Currently /64s should be used for PtP links. Yes /31's not working as most other routers and ...

first things first: initially /127 addressing where considered harmful for IPv6. http://tools.ietf.org/html/rfc3627 there are other RFC documents about IPv6 that will state that /127 address space should not be used. now when this is stated, you can use other than the address that ends with 0. for ...

I have a router.. 2 interfaces.. XXXX:f000:32:88::/127 XXXX:f000:32:89::1/127 I can route XXXX:f000:32:90::/127 -> XXXX:f000:32:88:1 fine... _but_ I cannot route XXXX:f000:32:90::/127 -> XXXX:f000:32:89:: it says XXXX:f000:32:89:: unreachable I'm actually trying to send ::/0 to the :0 address and sa...

I don't know if its a BUG on RC14 but I have a RB2011-UAS and I have a 3G USB Stick Attached to it via MicroUSB -> USB Adapter. When I go into PPP Client to set up the Dialer for it I don't get an option for the USB Interface.. only the serial interface. If I go into System/Resources/USB I can see t...

A couple of days ago I upgrade to rc13 and suddenly on my PS3 I would get disconnected from the PSN network all the time. So I downgraded back to rc12 and the problem has gone away. I have upgraded/downgraded a number of times and each time I go to rc13 the PSN network will disconnect after a short ...

I have a RB751U-2HnD running NAT to a PPPoE Connection on v6rc10 After a while (say 5-6 Hours) the web server gets slow and starts to kick me out of the web interface all the time. Then after a day or so the web server is not available at all. There is no excess memory usage. nothing in logs. Winbox...

You can do /31 on Mikrotik. Set interface to 10.99.99.1/32 and set broadcast to the remote end e.g. 10.99.99.2 do the opposite on the remote end. It is not clear to me. Can you please give us a config example? Thanks, oreggin Umm.. that is a work around (hack) for Mikrotik -> Mikrotik as far as I k...

People where talking about /31's not being useable on Mikrotiks quite a while ago. It is not like they are new in the internet world at all but when I was testing them even on recent software versions /31's would not work. With IPv4 being in short supply these dating using 2 IP Addresses on a PTP li...

Are you sure you used port 2-10 to connect, not port 1, which is firewalled? Your problem sounds slightly different than in the original post, as bhorrock wasn't able to reset it. I had no Link at all on the FE ports when anything was plugged in to when I got the Router . GE Ports came up but could...

I also tried a 100M Single Fibre SPF in our RB2011LS-IN and it didn't seem to pass traffic either . I tried changing all the settings and no data passed thru at all. (but link was up)

Looking for suggestions since my new RB2011L-IN is basically non-responsive. An RB751G purchased at the same time works perfectly. I received a 2011L-IN with exactly the same problem as you described. I had to reset it (with the little reset switch) before it started working. Maybe a common problem...

I have just experiences the same bug as you. I set it all up.. connected Cisco 887 Router and Assigned PD Network Correctly via PPPoE and I could surf the internet on IPv6 100% . Disconnected Cisco and reconnected and no PD now :-( Running 5.17 on same Hardware. Makes IPv6 via PPPoE useless as it do...

/ip firewall filter add chain=input protocol=icmp action=drop Place it at the top of input chain Blocking all ICMP is BAD.. I wouldn't suggest people doing this! Blocking all ICMP will breaks things Devil and is evil much better is: ip firewall filter add chain=input protocol=icmp icmp-options=8:0 ...

I also have come across this problem (RB1100AHx2 running 5.17) I think. Please can this be fixed in the next version :-) Also the "work around" for cisco.. I don't really like advertising connected routes into OSPF3 (and I don't use cisco anyway) :-) IPv4 OSPF works 100% IPv6 OSPF3 the bri...
