XS724EM/M4200-10MG-POE+ & MS510TXPP - Can't Force 1GB on MGig Ports for incompatible MR53E MGig AP
We own 3 Netgear MGig switches XS724EM / M4200-10MG-POE+ and MS510TXPP with any of these Switches if we attempt to plug in a Cisco Meraki MR53E AP (Supports MGig 2.5) the switch will show a 2.5G 'up...
Again for the records: There is nothing that stops the switch vendors from implementing a switch port from limiting the announced speed capabilities. Still, there must be autonegotiation handshake taking place - this is IEEE 802.3 mandatory for Gb and up. The IEEE person won't change this for Meraki. Configuring a MultiGig port to GbE (or only 2.5G or only 5G or only 10 G for the sake of it) is not similar to setting a MultiGig or Gb port to a fixed 100 or 10 Mb rate.
As the messenger here I understand you look for a solution - however it should be up to Meraki to properly work with standards compliant MultiGig ports on their AP product in question. Netgear does look into changing the specs and updating the switch firmware - but I doubt there is a high priority. That's the problem with vendors like Meraki (ref. MultiGig negotiation) or Ubiquity (ref. non-standard PoE, another pain) coming from a "closed" world.
Just to recap - This is a Confirmed bug with how the Cisco Meraki MR53E AP handles MGig..(it doesn't work unless plugged into a 1G port)
I've upgraded the M4200 to the lastest firmware.. what I need is to "Force" Netgear to "1G" on a specific MGig port.. I also need to capture all the traffic on the M4200 from this specific port from the time the AP is physically plugged in (before it gets an IP) to look at the traffic (I assume Mirroring port#1 to port#2 with a PC running Wireshark - if you have specific instructions/suggestions - that would be helpful
Meraki is saying I need to "Force" the port to 1G on the Netgear switch - others are saying this isn't allowed per IEEE 802.3bz standard.. I've contacted the IEEE Chairperson of one of the 802.3 Working groups (who happens to work at Cisco) that is asking me to quote "chapter & verse" where it isn't allowed for a switch vendor to manually set speeds on MGig ports and Netgear should offer a firmware update to allow this.. and their MGig device will work at 1G.. (the AP works at 1G if plugged into a 1G switch)Then in "3-6 months" they will upgrade the AP Firmware to allow 2.5G MGig.. I'm pushing this gets fixed "in a few days" as a Sev1/Pri-1 bug... any help you can offer would be appreciated..
