The only reason I am wanting to set it is because there  issues when it isn't set. I am in control of both ends but the Cisco optical port doesn't allow for being set to auto, it only allows for 10Gb Full with auto-negotiate.  It's common with Cisco because the standard only specifies auto negotiate for twisted pair.   I understand the argument "SFP+" can only run at their designated speed. That being the case, the ports should only be able to do 10Gb Full. I understand auto is easier BUT when you have a device with a 10Gb SFP+ port that doesn't support being set to 10Gb Full BUT does allow you to set it to 1Gb Full. That's renders those arguments moot.   I mean why would they be totally out of compliance and allow the port run at 1Gb Full but not let it it beset to 10Gb like its designed?         ...

We have already troubleshoot all of this with Meraki support fiber and SFP are all fine. The connection works fine when Meraki's are not part of the equation.   What get's me is in multiple firmware release they acknowledge the issue:   Updated the range of port settings available for MX95 appliances on the device local status page.   Added more speed and duplex configuration options for 2.5Gbps-capable ports on the device local status page.   Yet they say: Hello, Setting 10G through the Dashboard manually is not currently supported. You can submit this as a feature request using the "Give your feedback" button at the bottom of Dashboard pages. These requests are regularly reviewed by our developers and help shape the future of our products.    When the issue exist locally and from the dashboard.   ... View more

If that were true, the 10GB fiber links would shows they are running at 10GB full and not 10GB Auto-negotiate and advertising available speeds.   ... View more

Except they do negotiate do, at least Meraki's do. ... View more

I don't know10GB SFP+ isn't supposed to run at 1GB either but they do. And the SFP+ are 10gb because if I use them to connect two  Meraki's they run at 10Gb.   ... View more

Yes, the reason I am bothered by it is because I have multiple Cisco core with 10GB SFP+ ports.  Using compatible SFP+ on both ends of the link the connections is not stable be the Meraki runs at Auto-negotiate on the optical link and the Cisco runs at Full.   It's been tested with multiple Meraki firewalls, multiple MS switches, and multiple Cisco cores. It would not be an issue if Meraki devices supported something as  basic allowing a person to set all supported speed and duplex on the port.   It bothers me because it would seem like the should focus on getting just the basics working correctly before throwing features at the devices. ...

I can agree you are wrong.  A switch Identifying a port is set to auto-negotiate is not the same as the port identifying as not auto-negotiate full.   The point isn't moot either because I can make 10Gb SFP+ work at 1GB if I set both ends statically to 1GB. Problem is Meraki doesn't provide the option to do 10GB Full only 1GB Full.   That's cool the lower end Cisco auto-negotiate. The higher end gear doesn't. ... View more

Fortinet doesn't follow the standard. They clear state they support auto-negotiate.   ... View more

That just mean you don't use much fiber because fiber doesn't support auto-negotiate.  ... View more

I've been configuring Cisco devices since back when FE ports were considered fast. It's pretty difficult to screw up setting port speed and duplex on a port.     ... View more

Correct 10Gb auto-negotiate is only supported with twisted pair its not supported on optic   https://ieee802.org/3/10GBT/public/jan04/lynskey_1_0104.pdf https://www.ieee802.org/3/an/public/jul04/lynskey_2_0704.pdf This also means 10Gb optic ports are not supposed to support 10GB auto-negotiate and only support  10GB Full Duplex. There is a difference between the two. .    But Meraki doesn't adhere to that. So if a person uses a device like Cisco Catalyst that does adhere to the standard and won't allow a 10gb optical port be set to auto-negotiate you run into a port speed/duplex mismatch.   The problem here is the Meraki don't adhere to standard like other enterprise gear.    ...

10gb copper connections act as expected. They support 10Gb auto-negotiation which falls in line with IEEE standard.    The issue is Meraki doesn't follow IEEE standard when using fiber. Fiber should be manually set or only support 10g Full Duplex not 10G auto-negotiate. The Cisco devices we use follow the standard and require the port be set manually. The Meraki doesn't allow the port to be set manually.   In fact accessing the local interface of the  devices you wouldn't even know they support 10G.    ... View more

The issue isn't supporting Meraki branded or non-Meraki brands parts. The issue is more basic than that. If I buy a device, be it managed switch or firewall at the prices we are paying for these devices, I should have the fundamental basic capability to set speed and duplex on a port. I should have the ability to set a 10Gb optical port to 10Gb full.   Setting speed/duplex on a port is one of the most basic functions of a managed network device. ... View more

No that's not true because they are optical ports. 10Gb isn't supported on optical ports IEEE standards even says as much.   The very reason why the devices dont work with other network devices is because  they follow IEEE standard and Meraki doesn't. ... View more
