What is the function of PoE pass-through?

  • allows multiple physical switch ports to be aggregated together and act as a single logical link to increase bandwidth on trunk links
  • allows a multilayer switch to forward IP packets at a rate close to that of Layer 2 switching by bypassing the CPU
  • allows switches, phones, and wireless access points to receive power over existing Ethernet cables from an upstream switch
  • allows a switch to disable redundant Layer 2 paths in the topology to prevent Layer 2 loops

Explanation: PoE or Power over Ethernet allows devices such as wireless access-points and IP phones to receive power from PoE enabled switch ports. PoE pass-through allows a switch to receive power from an upstream switch and pass it through to PoE devices.
