Works, Observium now shows BGP Peering sessions, ASNs, Peer address, and session up/down and time established.

On which version please?

CyberDaeng

You mean OSPF, BGP routes or OSPF,BGP neighbor/peer status? SNMP support for OSPF and BGP peer status will be added in ROSv7. Currently BGP routes cannot be monitored over SNMP because it can cause slowdowns and route crash. Hi, is this works already in V7.13? Cause I still dont see any BGP Peer st...

I have exactly the same issue…

CyberDaeng

So its actually not hang. It just my keyboard is not functioning as well all the onboard LAN. So onboard USB and LAN doesnt work. I can access winbox thru the PCIe SFP+ card that I use with this server.

Maybe any advice for the onboard usb and LAN can be functioning?

CyberDaeng

Well, I have several routers run Mikrotik x86 with Dell Server with SSD SATA with no issue at all.

CyberDaeng

Hope someone can help me here... So I just bought Supermicro SYS-1019C-FHTN8 and everytime I try to boot Mikrotik x86 with this device, it always hang when coming to login. Probably it doesnt accept old kernel.

Does anyone have same issue and know how to deal with this matter?

CyberDaeng

Im also having the same problem with Dell Force10 S4810 and S60. Do you have the answer for this yet?

Incase anyone else asking, Finisar FTL4C1QE1C 40GBASE-LR4 QSFP+ Transceiver is perfectly useable for CRS354. I have tried it my self.

Does anyone ever tried Finisar FTL4C1QL1L 40GBASE-LR4 QSFP+ with CRS354? Can this works together?

CyberDaeng

Does anyone ever use Finisar FTL4C1QL1L 40GBASE-LR4 41.2Gbps 2km Duplex LC QSFP+ Transceiver Module in CRS354? Can it be use in Mikrotik CRS354?

CyberDaeng

it´s work. Pay attention to module compatibility. Use only intel compatible.

Thanks for the advice...

Hi, does anyone ever tried to use Supermicro AOC-STGN-I2S 10GbE SFP+ with Mikrotik x86? Because I have IBM X3250 M4 and one of the PCIe are half size so it can only use compact PCIe card. I was trying to get compact LAN Card but its also difficult and I accidentally found this Supermicro AOC-STGN-I2...

CyberDaeng

So what does /ip dhcp-client export and /ip dhcp-client print on that CCR show? Could it be that you normally use Winbox or WebFig with "skins" (or someone experimented with them in the past at least) and access to DHCP client configuration is hidden on the GUIs for the user name you use ...

CyberDaeng

Since the transaction ID is shown, dissection of the DHCP part must have succeeded at least partially although a malformed packet is reported, so open any of these packets in Wireshark (GUI) rather than tshark, unfold the DHCP dissection and find the client-id. Sorry I really dont have any idea rea...

If something else, what does /interface bridge nat export show? And what does /ip dhcp-relay export show? Nothing... It only shows the CCR type, system id and serial number So if you are bullet-proof that no /ip dhcp-client row exists on that device itself, run /tool sniffer set file-name=dhcp-rq.p...

Yes, the IX claims received DHCP broadcast from that MAC. And that is our MAC Address which used connect to IX BGP Session.
