Re: Uptime rollover bug/SNMP

Yep -- also we are always hesitant to upgrade firmware unless there is a specific issue to address. The risk of firmware upgrade and even just a reboot is not zero. We know that 6.44.3 & 6.44.5 work very well on hundreds of switches and thousands of customers. We're not in a hurry to change it e...

Uptime rollover bug/SNMP

Hello, About 497 days ago we deployed our first Mikrotik CRS326 switches running RouterOS 6.44.3 into production. Today they are one-by-one becoming unreachable via SNMP, and when viewing system uptime in the Web UI, it's becoming clear that the uptime counter is being measured in 32bits and has rol...

Re: CRS-3xx Learn Limit/Lock on first

Thank you for the reply -- but that's not quite what I'm looking for. Lock on first (https://wiki.mikrotik.com/wiki/SwOS/CRS317#Forwarding) does not require knowledge beforehand of the mac address. The port security feature for RouterOS requires static port-to-mac mapping, which requires knowledge o...

CRS-3xx Learn Limit/Lock on first

Hi, We need to restrict learned mac addresses per port on CRS326 using RouterOS. This was a feature in CRS1xx/2xx, and apparently is a feature in CRS326 using SwOS (Port Lock->Lock on first>. However, SwOS is too limited in other areas for us, so we use RouterOS on these devices. Is there no way to ...

Re: I'm unable to make flashfig work!

6.44.3 did not work for me, same problem with Hap AC2, unknown if other models affected.

6.39.3 worked.

CRS 3xx ethernet cable test

Do the CRS326 models not have the ability to perform cable test?

When I select cable test, it just says "Link OK" and doesn't give any additional information. This is on a CRS326-24G-2S+RM running 6.44.3

Appears to be just cosmetic. 8000 byte ping packet works when sourced from vrrp IP address with do-not-fragment set.

Re: CCR1009-8G-1S-1S+ how to monitor dual power supply?

For anyone who cares, you can in fact monitor both power supplies on a CCR-1009-1S-1S+ -- it's right there in system health, also available via SNMP.

access to more accurate UPS voltage via API or snmp?

It seems only the integer UPS voltage is available via SNMP: zabbix:~ # snmpget 10.10.5.10 SNMPv2-SMI::mib-2.33.1.2.5.0 -v 2c -c public SNMPv2-SMI::mib-2.33.1.2.5.0 = INTEGER: 13 And not at all via the API or CLI: <<< /system/ups/print <<< >>> !re >>> =.id=*1 >>> =name=ups1 >>> =port=usbhid1 >>> =of...

Re: CCR10009-8G-1S-1S+ Keeps Failing

We just lost 2 back-to-back that came in on the same order. They both were deployed in late February and died in early April within 2 days of each other. MAC addresses are only a few numbers apart. Both in air-conditioned, raised-floor data center environments. Have several in much harsher condition...

Did you ever figure this out?

I agree, two power supplies are useless if you don't know when one dies.

I'm using CCR routers, Mikrotik versions 6.23 and 6.24 I have an issue where, if a vlan interface is created with a bridge selected as it's interface, all tagged packets from the interface are flooded to all...

Re: Netbox 5 25.5 mile 5Gz Link

It must be something on your setup. I am doing a side-by-side comparison of Mikrotik NM5 AC and Rocket M5. The Mikrotik has about 4-6db better signal than the UBNT. These are connected to 2 RD30s on each end of a 22km link, mounted 5ft apart. The 3rd RD30 is for Chain2 but from what I read I need mo...
