MX450 : Do we have option to convert RJ45 port to a WAN port

[SobyKuruvilla]

Hi All,

I am in a such a scenario and  looking to see if there is an option to convert one of the 8 × GbE (RJ45) ports on MX450 device to a WAN port. Actual requirement is to get 2G uplink speed for the internet  and wanted to see if I can do a port-channel between one of the WAN port ( using 1G fiber SFP ie MA-SFP-1GB-SX module ) and one of 8 × GbE (RJ45) ports to get a total of 2G uplink bandwidth. Currently, i don't have any option procure any further sfp modules.

Welcome to any other ideas as well ( without adding any further SFPs modules 🙂 ) ..

Many Thanks,

Soby

Hi @SobyKuruvilla I'm not sure if you can change one of those ports to a WAN port.  I'll let another comment there.

However, for a Port-channel to work the media types need to be the same.  You can't bundle a fibre port with a copper port.

Thanks for prompt response. We can have port-channel of different media types. I have this scenario in production between Cisco catalyst and WLC with 2x 1G port-channel ( one fiber+one copper). Not sure if it is not possible for Meraki devices.

Thanks Again.

Hey @SobyKuruvilla ,

Unfortunately, you can neither convert a RJ45 port to be used for the WAN, or set up a port-channel as the MX does not support LACP. 

Your only option to get 2Gbps is to use an SFP+ module 😞

Thanks your reply.. 😞

Hi @SobyKuruvilla .  Apologies, my statement was incorrect.  It doesn't matter on the media types but comes down to Speed and duplex.  Doh
