MLT using 4 AP7532 Bridge

[Phil_storey]

Does anyone know if it possible to use 4 AP7532 setup as bridge between two buildings 2 at each site, as MLT ? Also to get highest throughput is it better to leave it as smart or set the channel to xxWW at both ends. Below is output for current bridge. I sure someone will understand this better than me )

Hi Phil,

I believe this would be as easy as having all VLANs as "allowed" while keeping one as "controll".
Consider it analogy to dot1Q.

Ondrej

Hi MLT = Multi link trunk, this would be at the network switch level

Hey Phil,

not sure what you mean by MLT, but you have probably two options:

PTP - Wireless Bridge

PTMP - MCX

The throughput is supposed to be validated first so once you have the link, do a stress test and decide on used datarates (considering LOS etc.)
