   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"...
