10Gb networking

Hardware MikroTik hardware general

Hi,

I’ve noticed that Mikrotik have the MikroTik CRS305-1G-4S+IN but it’s still only got a 1 gig up link effectively, or it’s powered by that port which I believe is also the uplink?

What’s the point of that having a 1 gig uplink and 10Gb throughput on the switch itself?

1G ethernet port is mostly for management in this switch.
However it is connected to same switch chip (not directly to CPU), so you can you use it for effectively passing traffic too.
And as an uplink to the router as well, if you want.

If not - use any of 10G ports.

Thanks, so if you want to use the 10Gb uplink, you effectively lose a port and if you’ve only obviously got one port available, you also lose the PoE in

If it’s “just for management” and you do use it as an uplink too, aren’t you uplinking at 1Gb?

I specifically didn’t say, that it is “just for management”, because unlike many other Mikrotik switches, that have a dedicated management port (that is 100Mb and goes directly to CPU), on this switch you can use it for passing traffic too.

So, overall you can use 1Gb port for:

  1. Management
  2. PoE in
  3. Uplink
  4. Downlink
    Or any combination of that.
    Same for any other port on this switch.
    Except for PoE-in, that can’t be used on SFP+ cages, so this function is exclusive to 1Gb port.

If you don’t need it - don’t use it, use other ports.

There is no specific “uplink”
