It's a matter of preference. I think Hyper-V is crap and that VMware is the best hypervisor for CHR. In all seriousness, there are pros and cons of each. If you already have Hyper-V in your environment then use that. If you have a VMware environment - use that. Keep in mind BGP is single threaded so...

Contact Mikrotik Support I'd say but first hide your keys!

We've all been there. Sometimes it's easy to go blind and oversee the obvious.

elbob2002

Isn't there an incorrect IP address? If you're using /30 that gives you a maximum of 2 hosts. On R2-161 you have 10.39.255.4/30 and 10.39.255.2/30 10.39.255.2/30 is fine because your network is 10.39.255.0 and broadcast is 10.39.255.3 10.39.255.4/30 is wrong because your network should be 10.39.255....

I have three CHRs in production. Spanning two locations in two countries via EOIP tunnels. One runs on ESXi 6.7 (AMD Opteron 6344) and two are on 6.0 (Intel i7 7700) I've never had a problem with any of them and they're upgraded regularly as you can see by the near identical uptimes.

elbob2002

There is a limit of 10 NICs per VM in ESXi.

So unfortunately it can't be done.

Run your own NTP server?

My DNS servers also double as my NTP servers.

elbob2002

What version of RouterOS are you running?

There was an issue previously with port flapping when an 100Mb devices were connected.

elbob2002

To be honest if you're running RouterOS then make sure you're running the latest version and you won't have to swap out any fans. Whatever changes they made means mine is practically silent with fans running at 270RPM instead of 4000RPM. Of course this is at the expense of temperature which is now 5...

*) crs328 - adjust fan speed based on SFP and CPU temperature;
*) health - improved fan control on CRS3xx and CCR1016-12S-1S+r2;

Yes indeed. I should have known better than to upgrade. Edit: This is a CRS328-24P-4S+

The Hypervisor is the obvious difference. There are a few here who swear HyperV is better for hosting CHR and others (myself included) swear by VMware. But I'm biased slightly as I used to work for VMware. I'm assuming you are using the P unlimited license as on my ProLiant DL385p G8 I only get 9.2G...

elbob2002

Do you need 4 SFP ports? For almost the same price you could get more ports albeit with two SFP instead of 4.The CRS326 has SFP+ ports. More ports are always handy if you want to add cameras etc. mtikswitches.PNG (I have no involvement with the reseller above other than I buy my devices from them!)

v6.45.3 is released! but when I tried to update my system then it shows an error windows defender error 577 , I really have no idea how to remove this error. if you have any idea about it then please share with me. How are you updating? The device itself downloads the updates if you do it through W...

elbob2002

Yeah. I understand the NAT side of it. it would be nice to have something like Carp from the BSDs. I know that the features of Carp aren't fully achievable on routerOS but I was seeing how close I could get.

Thanks again for you help!

elbob2002

Thanks Sindy,

I've made those changes but they don't seem to have resolved my issue. I'll investigate further today.

elbob2002

Hi all, I'm tearing my hair out with this one. I'm trying to set up VRRP and have two CHRs (6.44.5) configured successfully with External VRRP interface (EXT) and internal (INT) VRRP interface Everything on LAN is configured to use the virtual IP on INT as their gateway (192.168.80.254) and can ping...

elbob2002

Glad to hear you got sorted.

elbob2002

Use a SRC-NAT rule on the IPsec interface (out interface). That way all traffic from your IP pool or corporate LAN should appear to come from the IP address of your IPSec Interface.

elbob2002

After 13 days and 18 hours following an upgrade to 6.44.3 my core switch had an unscheduled reboot. The switch is a CRS328-24P-4S+ running RouterOS as SwOS was causing so many issues. As this is a coreswitch, several devices powered by PoE also rebooted from loss of power resulting in considerable d...

elbob2002

You need to resize the disk before powering on the VM for the first time.

It should automatically resize on the first boot.

elbob2002

Can you check please the fan speed too?

Sure! From LibreNMS:

CRS328.png

elbob2002

Sounds good! One more question: does this also mean that if I have only a limited POE power request (8 devices with max 7 Watt/port) then my device won't turn on the fans? How it goes in your case? I only have 4 PoE devices connected to mine: ether1 ether2 ether11 ether24 poe-out: auto-on auto-on a...

elbob2002

I had the same issue and changed from SwOS to RouterOS which resolved the fan issue I was having. I had a thread here somewhere about it.

At the moment it's running perfectly on 6.44. as it's a core switch I haven't had a chance to update it in a while.

elbob2002

Most likely the firewall configuration prevents you from connecting on the public IP address:

You seem to have consistent results with and without hyperthreading (with the exception of the last MTU setting) . I'm wondering if you're not hitting a limitation elsewhere?

You could try using iperf on a couple of VMs?

elbob2002

Yes you can. With RouterOS only though.

elbob2002

I'd be curious to see what performance you would get with hyperthreading disabled on the hosts.

elbob2002

It would be helpful to know where you are.

I could make a recommendation but I doubt my Irish insurer would cover you if you are based in another country!

elbob2002

elbob2002

I had the exact same issue with the same model. I have a thread on it here somewhere. Turned out there was nothing wrong with the unit. It was SwOS. I changed over to RouterOS and it's been running fine since. SwOS 2.9 has been released since but unfortunately mine is in production now so I can't ma...

elbob2002

There is a setting in the swOS web admin to boot to RouterOS. I can't recall exactly where it is but it is there as I used it on my CRS328. License should be there automatically so you won't need to install one. It shouldn't void your warranty either. I would recommend changing from SwOS to RouterOS...

elbob2002

A SwOS device will appear in the neighbor list in Winbox but you cannot connect to it using winbox. Double click on the SwOS device in the list and it will open your default browser to the device's web page. However if it doesn't have an IP address then of course you will not be able to connect. As ...

elbob2002

A reset should do it for you. Quickset as WISP AP and make sure Bridge All LAN Ports is ticked.

elbob2002

SwOS isn't available for the CRS125.

To ensure it's in switch mode simply create a single bridge and have all ports (interfaces) as members of that bridge.

edit - I forgot mention you need to be running 6.41 or higher I think for that to work.

elbob2002

I ran in to similar issue in my lab setup.

Reducing the MTU on the MPLS interface from 1508 to something lower (1472) worked for me. Had to do it on all MPLS devices.

elbob2002

You will have to enable promiscuous mode on the vswitch or vswitches the CHR is connected to. On VMware that is.

elbob2002

are you using SwOS or RouterOS? Which verison? I did have an issue with one port not powering a device and just plugged it into another port and it worked. I thought maybe I hadn't pushed in the connector properly. I'm running RouterOS 6.43.7 on mine. Routerboard firmware is 6.43.4 because I can't r...

After seeing this thread yesterday I bought two CHR P10 licenses. Seamless order processing, outstanding value and I had the keys in my Mikrotik.com account this morning.

I'm based in the E.U. though so not sure if being outside the E.U. would make much of a difference.

elbob2002

I gave up on SwOS in the end. Booted to RouterOS and haven't had any issues since.

elbob2002

Mine says 2.8 (built at Fri Jul 13 2018 12:37:17 GMT+0100 (IST))

However I see there is now an update available:

Latest Available Version 2.8 (built at Wed Oct 03 2018 07:02:09 GMT+0100 (IST))

Will upgrade later this evening and see how it goes.

elbob2002

The only thing that worked for me was to reboot the switch.

I had a power failure here recently and since the power came back I've had no issues since. It's very strange.

elbob2002

The only way I got traffic across VPLS tunnels was to set the vSwitch to promiscuous mode anyway. Also had to change the MPLS MTU to 1478 on ESXi 6.7. Before making these changes I was only able to ping, traceroute etc. Transferring large data would stall. Also because of my own VLAN requirements I ...

elbob2002

What is the CPU usage? How many cores have you assigned to CHR?

Finally have you enabled FastTrack?

https://wiki.mikrotik.com/wiki/Manual:IP/Fasttrack

elbob2002

Forced a reboot of the switch and fans are working again!

CPU Temperature 39C
Board Temperature 35C
FAN1 4440 RPM
FAN2 4410 RPM

elbob2002

I’m out of the office now but thanks! I’ll try reinstalling the update and post my results here.

elbob2002

Buy a CHR license. It's only $45

elbob2002

SwOS 2.8 was released this morning and has several fixes for SFP. Time to upgrade and see?

I have a CRS328-24P-4S+ and I just noticed that on the download page that SwOS 2.8 is released. However there seems to be no version for the CRS328. Is one of the other firmware compatible?

You probably could but you may need to rename or remap interfaces and adjust firewall rules etc.

Also the RB3011 does not have a wireless card.
