i've seen similar but only once in all the years i've done networking
infrastructure... that was when adding a new switch to an existing network
made of apple-gear... it finally turned out that the new switch had a slightly
different implementation (read more modern) of jumbo-frames than the old apple
gear already in place... since these were all unmanaged switches, the only
solution was to replace the new one with one that understood the older format
being used...

the most common switch problem i've seen has been poor ventilation and heat
removal... the switches are simply overheating... i have actually removed
switch guts from their housings or even simply opened them up and the problems
have gone away... this is especially true with consumer-grade gear... some
cheap corporate-grade gear has the same problem, too... it is what happens
when you let decorators design your equipment housings to "make them pretty"...
