The only "security risk" i see there is number 1, and that is all to do with physical security. > Disadvantage #1 – Open ports on unmanaged switches are a security risk Why? Is there something that would prevent an attacker with physical access from unplugging an existing cable? Does the average managed switch config have mac limits and auto shutdown if a link is lost for just a few seconds? Mac limits are easilly by…
> If your switch is dropping packets, you don't have enough bandwidth.
this isn't true, there exist more bottlenecks than just bandwidth, e.g. try sending 10 byte packets instead of 1500 byte packets and watch as your switch starts dropping due to CPU exhaustion
> Ultimately it comes down to how big your buffers are whether your packet gets through or not
not really, traffic prioritisation is about deciding which packets you drop when hitting your limits (or close to), not making sure that you never drop anything
obviously if you're never hitting any bottlenecks: the prioritisation does nothing
