The aggregation (sometimes also called distribution) layer is a real crossroad. Its primary goal is to increase network scalability by providing a single place to interconnect multiple access switches and the core layer. By bundling multiple network connections into a single high-bandwidth link, aggregation switches help. Function: Connection point for all devices on a segment of segment of a network that breaks down and absorbs the data flow between all of the connected devices rather than flooding it to all connected devices. Generally, these are used for two-tier or three-tier hierarchy networks. I'm not an employee of Cisco/Meraki.

If possible, check if the PD can turn on with another PoE switch or with an external power supply. Check that the Ethernet cable that you are using is of good quality. This document describes how to troubleshoot Power over Ethernet (PoE) on Catalyst 9000 PoE-capable switching platforms. Cisco recommends that you have knowledge of these topics: • Catalyst 9000 Series switches • Power over Ethernet This document is not restricted to specific software and hardware. When a problem occurs with PoE, in most cases, the error symptom can be simply shown as the PoE switch not providing power, and the powered devices will stop working. The cause of failure may be attributed to many factors, including hardware device factors and software factors. How to precisely. If PoE stops working, PDs simply shut off. Here are some relevant pointers. PoE (as a general standard, not referring to 802.
