MX250 and fiber aggregation?

[JMY34]

We use a couple of Meraki MX250 switches at the small school district I work in. Recently our ISP bumped us from 1Gbps to 10Gbps, and I was wondering if we can use our MX250s to aggregate Fiber connections between our schools to 20gbps. Does the MX250 support that, or can I just do 10Gbps? Thanks.

Yes, you can, the maximum stack bandwidth is 80Gbps.

To clarify, are you talking about MX250 security gateways, or MS250 switches?

The MX security gateway line does not support link aggregation.

The MS switch line does support link aggregation.

I was talking about the MX250s. I can see what kind of switches we have, but I think they're only MS75 at best, some are a smaller number as well. Can I at least see about changing our Fiber cables over to 10Gbps on the device our fiber internet comes in on?

[alemabrahao]

What you are talking about is confusing. MX is a firewall and not a switch. And MX doesn't support link aggregation.

Can you send a photo of the equipment so that we can help as best as possible?

Here is our main MX and first 48-port switch. I noticed that the Elementary School and High School are only getting one strand of fiber. MX48-port switch

Sorry buddy.

LACP & Link Aggregation

The MX does not run LACP or any link aggregation protocols. Connecting aggregated ports to the LAN of the MX is not supported; all connected ports should be un-aggregated. If multiple ports are connected to the MX from a single switch for redundancy, it is highly recommended that you run STP on that switch, to ensure that one of the redundant ports is safely put into a blocking state.

It's okay. Any problems you can see based on the photos? Should I look into adding another fiber strand to the Elementary School and High School? And is it still worth seeing if I can upgrade the fiber cables going to the MS250s in other locations? Thank you.

[alemabrahao]

Sorry, but I still can't understand exactly what you're wanting to know.

Taking into account only the images I cannot express any opinions about your network, first because I know absolutely nothing about your network, second because your question is very subjective.

[JMY34]

Our ISP just upgraded us from 1Gbps to 10Gbps, and I was wanting to make sure our other schools were getting the full 10Gbps if possible. The switches we're using are MS225s. I don't know if those support aggregation.

[alemabrahao]

Yes, the MS supports link aggregation. It has 4 SFP+ ports

You can easily check it on the datesheet.
