RB2011 runs wireguard just fine. It must be some issue with your config.
Btw current firmware should be upgraded.

Hi,

Other possibilities:

Wireless 4G modem and setup VPN access for remote managment.
Monitor UPS through USB.

As soon as a port is bridged performance suffer.

RB2011 with a couple of VLANs. Only low bandwitdh traffic so no load to speak of. Up to 7.8 no problems. With 7.9 two (of about 20) connected devices on different VLANS have problems. On one VLAN a Veriphone PoS device renew IP every 10 min despite 2h lease configured. It works but why? On another V...

Six years ago Mikrotik told us that "802.3ad compatible mode is currently not supported" viewtopic.php?p=524163&hilit=crs112+lacp#p523721.
This to me implies that LACP support could have been implemented, but for some reason never did.

Yes, as long no configuration changes are needed Unfifi AP's will still function. Of course configured hotspot etc.will not function if controller is offline. On UI controller you define vlan only network and tie those to SSID's (Wireless networks). Once AP's have provisioned they will bind SSID to ...

andkar

AP contacts controller for managment, not the other way around. This makes it possible to move AP to another network as long as it can reach the controller.
This is one of the functions that is good about Unifi. I do not like the other stuff (no to be discussed here).

andkar

" hybrid port everything" Default management is untagged. This can later be changed so AP only communicates through tagged VLANs (if desired). The important point is that AP needs initial connection to controller in order to be adopted. Then it is possible to assign management to a tagged ...

Yes, new 24-48 PoE switches would be nice. And with beefier managment resources than what latest MT switches has gotten.
Wanted - More RAM, more storage and more CPU.

Btw, it seems that new CRS510-8XS-2XQ-IN got 128MB RAM and 32MB storage (twice of what CRS 518 have).

Yes, managment though winbox can easily consume 25% CPU on this device. This load should not affect swiching performance (provided cpu does not take part in swiching, see below). 1. switch-1 cpu should only be member of VLAN 99 2. Only one VLAN interface needed: /interface vlan add comment=MGT inter...

andkar

Sorry I meant VLAN interfaces, not "bridge VLAN interfaces".

Here is an example where VLAN1010 is mangement VLAN.

andkar

Hi,

Why all bridge vlan interfaces? Only mangement is needed.
Try removing all bridge vlan interfaces except the management interface VLAN_99 and test again.

Hi,

CRS112 does not sopport Bridge HW offloaded VLAN configuration. VLAN configuration on CRS112 should be done on the swich, not bridge. At least if wirespeed if desired.

Hi,

See this thread viewtopic.php?t=185242 It seems to be bridge bandwidth issues with RB3011 and v7.

andkar

And if I do the same test with RB2011 there is no difference in performance, bridge or not.
Clearly performance issues with RB3011 and ROS 7.1.

andkar

Yes,
Test with internal interface outside of bridge: RB3011 performance increase from 280 to 520Mbit/s without fasttrack.

andkar

I did a quick test with IPerf3 ( -P 10) on RB3011 and RB2011. Both default config (netinstall).
RB2011 with it's weak cpu (600MHz) can almost keep up with RB3011 (2 x 1,4GHz). Just 80 Mbit/s more on RB3011 without fasttrack, 280 vs 200.
Something seems to be wrong with v7 and RB3011.
