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
