Hello Everyone, I am new to Open vSwitch. I would like to gain some insight into the way we can capture (i.e., detect) a link degradation (i.e., partial failure). For instance, if a link has capacity of 10 Gbps, but degrades to 1 Gbps, does OVS capture this?
>From what I understand, if we have *bond-detect-mode* set to "*carrier*" for all our links, a complete link failure will be sensed by the Open vSwitch, and this information can then by propagated to a centralized controller. But what happens if there is a degradation instead of a complete failure? Perhaps one way out is to use the LACP configuration and have multiple links with different capacities between nodes, and have one of them turned off. But I think that would not properly simulate the case of the real world issue of partial failure. Unfortunately I have not been able to install OVS correctly on my Ubuntu machine, so I cannot test this stuff at the moment, but it would be nice to gain an insight from senior OVS practitioners. Perhaps we may have to use a combination of other statistics that are on offer to gauge such a partial failure?
