Aggregate Wireless PTP LInks
Posted on 2014-12-29
Brief - is it possible to aggregate two wireless PTP links in order to double throughput and potentially reduce latency between locations?
We have two pairs of wireless point to point links (Cambium PTP600) configured from one building to another. Both pairs are connected to HP Procurve V1910 switches. On both switches, I've created dynamic bridge aggregation interfaces with two selected ports. (Possible side note - I have also configured BAGG1 as either Trunk or Hybrid link type with no effect on the connection.)
When I plug the devices into the aggregated ports, the status of both member ports shows as "Selected". However, the connection still seems to be operating via only one of the two PTP links. The throughput nor latency are affected (exactly the same as when only one PTP link is connected). If I pull one of the links, the connection does cut over to the other link after about 30 seconds so there does appear to be fault tolerance. And lastly when all four Cambium devices are plugged into aggregated switches, I lose HTTP management access to three of the four (and it's restored when I unplug any one of them).
Does it sound as though I am not configuring the switches properly or is there something about wireless PTP links that would prevent them from configuring in the same way wired links would? Thanks very much in advance!
