Performance on CCR2216-1G-12XS-2XQ
by Shane Clay 19 Feb '24

19 Feb '24

Hi All I've got my hands on a couple of CCR2216-1G-12XS-2XQ fitted with XQ+85MP01D 100G transceivers. Just doing some initial testing using the built in BTest Server & SpeedTest tools as a bit of initial benchmarking. So far I haven't been able to get up to 100G. The instantaneous throughput I see in the interface list is round 50G for TCP and 75G for UDP. There is absolutely no config on the devices (queues, firewall rules, etc). Interfaces are showing auto-negotiation at 100G full duplex. My guess is that this tool isn't up to the job of maxing out the link but iPerf would probably get it up there. Thoughts?

CCR2216-1G-12XS-2XQ compatible with 10G SFP+
by Shane Clay 29 Jan '24

29 Jan '24

Hi All My research is coming up short! Can anyone confirm (or not) if the SFP28 ports in CCR2216-1G-12XS-2XQ are backwards compatible with SFP+ 10G transceivers?

EP06-E dropouts
by Jason Hecker 26 Jan '24

26 Jan '24

I have an LHG with an EP06-E module fitted running to a tower about 10km away connected to Telstra. It's been OK for the most part but lately the 4G link has been flapping several times a day, sometime with long periods of silence. The logs show nothing awry apart from the LTE link going down and DHCP not happening. Has anyone else noticed robustness issue with this module? I have set system reboots at 5am to try and help but it keeps happening through the day.

/31 Deployments for Point-to-Point links
by Christopher Hawker 09 Jan '24

09 Jan '24

Hey all, Trying to stand-up a BGP session between a CCR2004-1G-12S+2XS and a CCR2004-16G-2S+ using a /31 for the link. I'm able to ping across the link no problem, however, the BGP session doesn't establish. I'm attempting to move an existing session from a /30 where it works in order to conserve IP space. Is there some skullduggery going on, or is 7.13 just not RFC3021-compliant? Thanks, Christopher Hawker

RBwAPG-5HacT2HnD losing 5GHz radio?
by Damien Gardner Jnr 23 Dec '23

23 Dec '23

HI all, Kinda pulling my hair out with this one.. Hoping someone has a suggestion. I have a RBwAPG-5HacT2HnD, love this thing. But yesterday morning we started getting weird outage alerts from monitoring at home, with some devices being offline. (The main kicker was the cubby lol) When I got home from work I went looking, and finally tracked it down to wlan2 being missing.. A reboot brought it back.. But 10 mins later it was gone again. Rebooted it a few more times, then added remote syslog, and went to bed. Got up this morning, and remote syslog really wasn't any use at all (I assume there's some specific prefix I should have been punting to remote syslog to catch the device going away), and now reboots aren't helping, it has to be a physical power removal and re-application.. Thankfully I have a spare (Got one on ebay at the start of the year, and had meant to set it up at the back of the house), so have just finished copying the config to it, but would love to get this one working properly again.. Was hoping it was just mini-PCIe cards or something, but alas no. Has anyone had the 5GHz radio go away on these? And fixed it? It's 4 1/2 years old, so I'm pretty sure it's out of warranty period 🤣 Thanks, DG -- Damien Gardner Jnr VK2TDG. Dip EE.

Proscend PS180-T VDSL SFP Modem EOL
by Tim Sandy 12 Dec '23

12 Dec '23

I'm quite sad to have just discovered that the PS180-T is now EOL, does anyone know of a similar product out there? I've got them at quite a few sites and would really love to avoid running an external modem in bridge mode. Cheers, Tim

ROS6->ROS7 and BGP
by Tim Warnock 17 Nov '23

17 Nov '23

Hey Guys, I ran an experiment to upgrade a ROS6 box to ROS7 to see what it looks like and found at least the following things: 1 - route "check" tracking doesn't seem to work? 2 - no-exports set on routes towards EBGP peers are interpreted rather than forwarded - so you can't signal to EBGP peers to no-export your routes from outside of their ASN anymore. 3 - it appears that the route policy conversion bugs out if one of the entries is disabled so you have to be prepared to fix any entries that are missing. 4 - you can no longer set the ASN of a route being advertised. (would need to update RPKI information) 5 - non-synchronous network statements are gone, so you can't easily send scrub communities via BGP anymore (because a legit route now has to exist in table). 1,2 and 3 feels like bugs, the rest I'm not sure why the functionality was removed. Anyone successfully spoken to MikroTik about what their thought process was with the changes? (I opened a ticket for 2 and it was ignored.) Thanks Tim

Puzzled why forwarding no work
by Karl Auer 08 Nov '23

08 Nov '23

Some may recall I now have a Wireguard VPN between a Starlink-connected site and another site. The other site has a static IP address, the Starlink site does not. Inevitably, someone now wants to connect from outside to a server in TCP/85 in the Starlink site. No problem, thinks I. They can connect to the static IP and I will ship their connection over the VPN to the other network. Just dstnat plus srcnat. In the following, xxx is the static IP address, and 192.168.103.184 is the address they want to reach in the Starlink-connected network. /ip filter nat add chain=dstnat action=dst-nat \ dst-address=xxx dst-port=85 protocol=tcp \ to-addresses=192.168.103.184 to-ports=85 \ in-interface=e1-uplink log=yes log-prefix="A" add chain=srcnat action=masquerade \ ???? out-interface=wg0 log=yes log-prefix="B" I can't figure out what I should put in the srcnat rule that will limit it so it only src-nats packets coming from the public internet. The obvious one, filtering on "in-interface=e1-uplink", isn't possible with srcnat. What am I missing? Or do I have to add "accept" rules for all the networks I don't want NATted by wg0?

Sanity Check on Route Filters
by Christopher Hawker 06 Nov '23

06 Nov '23

Hey all, Just looking to get a sanity check done on a route filter. If an AS is receiving routes from an IX route server, will this allow routes from the RS to be received? I'm confident it will, however just looking for validation before we test it. /routing filter rule add chain=AS64496-V4-IN disabled=no rule="if ( bgp-input-remote-as 64496) { set bgp-local-pref 200; accept }" Regards, Christopher Hawker

40G QSFP+ Card Support on Mikrotik ROS x86
by Christopher Hawker 30 Oct '23

30 Oct '23

Hi All, I'm currently trying to source a dual-port QSFP+ card that is supported on ROS x86 (bare-metal). Are there any cards that people know of that are supported? We are trying to avoid the overhead of virtualisation that comes along with running CHR on a hypervisor. Thanks, Christopher H.
