Configure the QSFP+ ports on the CR328-24S-2Q-RM

Tue Sep 13, 2022 12:49 am

I am trying to configure the (2) QSFP+ ports to support a 40G twinax (aka DAC) cable. By default, they seem to be configured to support a 4 x 10G break-out cable

Where do I find instructions on doing this?

I am consulting the following:
https://help.mikrotik.com/docs/display/ ... tswitching
https://wiki.mikrotik.com/wiki/Manual:S ... p_Features

But I don't see any discussion of an /interface/ethernet xyz command which even mentions the "qsfpplus1" and "qsfpplus2" ports

None of these options seem to allow me to change the port from "split into (4) 10G channels" to "present a single 40G QSFP+ port"

Im not sure personally but have you tried disabling auto negotiation and trying to set the interface 'main' interface speed to 40gb and see if the other 3 slave interfaces disaprear?

Hard-coding speed & duplex seems to work

[admin@MikroTik] /interface ethernet> set qsfpplus1-1 auto-negotiation=no speed=40Gbps full-duplex=yes
[admin@MikroTik] /interface ethernet>

Though the other subinterfaces still show up ...
[admin@MikroTik] /interface ethernet> print qsfpplus1-1 detail
expected end of command (line 1 column 7)
[admin@MikroTik] /interface ethernet> print detail qsfpplus1-1
expected end of command (line 1 column 14)
[admin@MikroTik] /interface ethernet> print detail

How do I print just the details for qsfpplus1-1?
And ...
How do I print the make/model of the transceiver which the switch sees inserted into qsfpplus1-1?

How do I print just the details for qsfpplus1-1?

This way:
/interface ethernet print detail where name=qsfpplus1-1
