Usually SFP's adhere to standards like 1000BASE-SX or 10GBASE-LR or special types like BiDi, BX, ER, ZR which describes several requirements like wavelength, type of led/VCEL/laser used to transmit signals and more.  All SFP's of the vendors then comply with these standards so a switch from vendor A will successfully make a connection to another switch/router/server's SFP module. Usually in ethernet standards you have ports running a single speed like 1 Gbps and only support SFP modules.  But you also have dual speed ports like 1/10Gbps SFP+ ports.  And even beyond 40/100Gbps ports.   If your customer has an old fiber plant you'll need to stick to 1 Gbps links but you could bundle 2 or 4 or 8 links to upgrade your inter switch bandwidth that way. ...

It's 2021 and this seems to be the same issue I'm fighting.  I have a ticket open to discuss with Meraki, now to clarify that the MX Content filter is indeed being applied to the MR WAP itself, preventing my group policy with relaxed content settings from having any affect on my wireless clients. If I follow your found fix, the only thing missing from the original config is the new SSID no longer prevents clients from seeing each other as it did when it was the Meraki NAT mode.  Is that correct? ...

I was wondering if it got any better, waiting for the IPV6 Beta so I can get my MX100 off the Shelf and try it out again.  I wasted over a year of licensing since we cannot use it due to the IPV6 limitations.  ... View more

Opening ticket to the support and they confirm the cause of network down is because MX overload, the event dropped log is because of spike of traffic that not getting logged on MX utilization. Maybe its time to look for bigger firewall. ... View more

Are you in the position you actually need a sustained 1GB of WAN traffic   There is also no law that says that site-2-site traffic has to use the same appliance than internet/guest internet traffic.   You could very well have your core switching have internal routes pointing towards SD-WAN MX appliances (enterprise license) and have internet traffic pointing towards another pair of MX'es (different org with advanced license).   I know it is expensive but having a 1 GB link is an investment. ...
