Mismatched MTU, Bad Modules, Power Failure and Missing Routes This lesson continues to cover trouble shooting common wire and switch issues and discusses the following:

  • Mis-matched Maximum Transmission Unit (MTU)/Black Hole: packets are too large for a certain 'hop' and are dropped. If no error about the packet is received, essentially we've hit a Black Hole.
  • Bad Modules (SFP, GBIC): Bad port module on device
  • Power Failure: Device may have lost power
  • Bad/missing routes: routing information is incorrect
