Combo port with 4G on CCR1009

RouterOS General
1

Hello,

I’m using a CCR1009-4G-1C-S+ with a combo port including SFP/Copper port.

I was wondering if it’s possible to use the combo port with a Fiber on the SFP and a 4G via Chateau on the copper port?

If it’s possible;
will there be an automatic toggle when the fiber is down ?

Thanks

No my understanding on the combo port is that you can only use one of them at a time. Its not two ports its an either or port. I may be wrong but that is my understanding

Yes, you can change it with script:

/interface ethernet set [ find default-name=combo1 ] combo-mode=copper

/interface ethernet set [ find default-name=combo1 ] combo-mode=sfp

can be:

auto - the default
first plugged, first served
on reboot SFP take everytime the precedence
for SFP to considered active just be plugged the SFP (also not compatible) module

sfp - obvious, only the sfp

copper - obvious, only the ethernet

sfp-alt - I do not know what is for, I do not have any spare for test, only on productions…

Thanks rextended,
I reread the literature and its more than I thought.
Combo-port - a single 1Gbit software interface that has two hardware interfaces - an SFP cage and a Gigabit Ethernet port, allowing you to use any type of connection available to you. It is also possible to switch between both physical interfaces in RouterOS. In an event of disconnect the combo-port provides hardware fail-over feature.

I may have to rethink what I do with the combo port.

Thanks for replying.

I meant to use combo-port as a fail-over, with the Fiber wan as a main network and the copper (4G Link with Mikrotik Chateau) as a Backup.
The point is to toggle to the 4G if the Fiber is down.

With many researchs and some externals helps, i’m feeling confident with a very simple setup;

SFP port - Fiber link
Copper port - 4G Link

Route failover

/ip route add gateway=192.168.1.1 distance=1 check-gateway=ping
/ip route add gateway=192.168.2.1 distance=2

Check if primary link is up, and after 2 timeouts it will mark the gateway as unreachable and t hen default gw with metric 2 is used instead of the metric 1.

but you must change with script what interface is active, or all not work as you expect…

Alright,
Thanks
