MR52 and MR53 ports

can the second ports on these AP be used for downlink connectivity like Apple TV or printer etc, if yes is there a documentation on usecase ?

Re: MR52 and MR53 ports

Nope

That second port is for bonding both ports together via LACP, you know, for that elusive unicorn of being able to go over 1Gbps on wireless. Insert 'el oh el' symbol here.

You're clearly not using 80MHz channels.

Re: MR52 and MR53 ports

Thanks I saw that, so you are saying it can only be used for bonding and not individually for downlink connectivity ?

have you tested it, unfortunately I don't have one of these APs to test.

Re: MR52 and MR53 ports

@jdsilva  You sir are correct, at least not for enterprise. Rocking it at home, but I don't have any 3-stream clients, or 4 stream clients (not sure who does) and/or crystal clean RF always 5 feet away from my device =).

 

Actually...the datasheet for the MR53 touts that it can do 160MHz. Where? I see no option for this, not that I have any clients that support it. just curious

 

@ammahend I have not tested this, I am strictly going off the documentation. If it is/was possible, I would imagine that they would say so. If its a secret, then its a sneaky one.

Good find @BrechtSchamp 

 

Wish they would specify which model supports that. Unless that is some really old document from long ago.


I'm sure it 'CAN' be done via software though, if they wanted to.

Good link @BrechtSchamp , but I see a devil in the detail there:

 

"The wired port of an Access Point acting as a repeater"

I think the way you need to read that is that APs with one port can also do it, but only if functioning as a repeater (which is obvious because otherwise the port is in use).

 

That said, the reason I said it might work is exactly this, I haven't tested it.

Re: MR52 and MR53 ports

Actually the second port can be re-configured, but it can only be done by support, and you have to open a ticket to do it.  On the whole it is a pain in the arse, so I wouldn't do it unless you already have the kit and really need to.

 

If it is a for a small low density area, have you considered using the MR30H?

"although 160 MHz is not suitable for enterprise deployments or supported in the Meraki dashboard."

@jdsilva 


What the heck lol.  Well thanks for finding that for me.

Re: MR52 and MR53 ports

thank you all for your response, you are right, this ia a beta feature and have to engage TAC to enable it.I got to know from one of the SE.

Kind of a big deal

Re: MR52 and MR53 ports

Thanks for the feedback. I wonder if it works without the port profiles feature though. In other words, if you're okay with having one global setting that determines what happens when you wire up a client to an AP. The way I see it the port profiles feature allows extra configuration, i.e. specifying VLAN per port per AP.

 

From that link it's also mentioned that the global setting would be ignored for the MR52, MR53 and MR84 once that's enabled.
