MX250 - WAN Port 1G & 10G?

[NickSpeechley]

As per the the MX-Family Data sheet https://meraki.cisco.com/product-collateral/mx-family-datasheet/?file

It mentions that the MX250 has 2x 10GbE SFP+ WAN ports. Can a 1Gbit SFP work on these ports or only 10GbE SFP's? This is important to know as only our DC services have 10Gbit interface handoffs.

Hi Nick,

Yes, this question was just recently handled, but the question was if the 1 GbE coppar SFP was compatible. Have a look on this thread below. As I understand it has been tested and it does work with 1 Gb SFP in the 10 Gb SFP ports.

Here are the compatible SFP matrix to Meraki also for your reference.

@NickSpeechleywe use Cisco GLC-T modules in the SFP+ ports of our MX250s and they have been good for over a year now with the 15.x firmware train.

Thanks Claes_Karlsson, i did see the SFP datasheet but i didn't find it mention whats compatible for the WAN SFP ports in comparison to the LAN SFP ports and the MX datasheet just says 10GbitSFP+ for the WAN ports without specifying the 1Gbit so i was a little thrown off.

We also have MX250 running at a customer in three DC's..

Same "problem" because wou only could connect at 1Gbit with copper (at least preferred by co-lo partner)

We also used  the original meraki rj45 convertor on 1gbit.

Works like it should.
