3750 vs 3560

  • 3560's and 3750 are eventually the same switches.The only difference is that 3750's switches are based on stacking capabilties. They have a High-Speed stacking bus to give stacking capabilties.
  • Switching capacity (ignoring stack ring) is the same
  • 3750X can be stacked 2x (unidirectional 32Gbit)
  • the 3750X can also share power across stack member

C3850

  • WS-C3850-48T-L + 4xSFP+ module.
    • length 45cm !
    • stacking 480Gb/s

expansion module2

  • X2 - older (Catalyst 3750-E, 3560-E, older 4500 / 4600) - it is only “converter”
    • CVR-X2-SFP10G (Adapter OneX)
    • one X2 slot = one SFP+ port
  • Catalyst 3750-X / 3650-X only - network module (connected to dataplane)
    • C3KX-NM-10G
      • 2x 1GB SFP or
      • 2x 1GB SFP or 10GP SFP+ (dual role)
  • C3850 - network module (connected to dataplane 480mbit)
    • C3850-NM-2-40G 2x40G QSFP+
    • C3850-NM-2-10G
