LLDP Support on Cisco Meraki Products

Link Layer Discovery Protocol (LLDP) is a layer 2 protocol used to provide automatic discovery of connected devices and their capabilities. All Cisco Meraki devices support LLDP to varying degrees and send LLDP at 30 second intervals. This article will discuss each platform's LLDP support in more detail.

MR Series Access Points

All MR Access Points (APs) support the use of LLDP for both identifying themselves on the network and negotiating power needs when connected to a power over ethernet (PoE) capable switch. Below is an example (not representative of all deployments) capture of an LLDP frame from an MR16. Among other pieces of information, it indicates the AP's...

MS Series Switches

All MS Swtiches support the use of LLDP for both identifying themselves on the network, informing Voice of IP (VoIP) devices of a tagged voice VLAN, and negotiating PoE with compatible devices. Below is an example (not representative of all deployments) capture of an LLDP frame from an MS220-8P. Among other pieces of information, it indicates the switch's...

MX Series Security Appliances & Z1 Personal Gateways

All MX Security Appliances and Z1 Personal Gateways support the use of LLDP for identifying themselves on the network. Below is an example (not representative of all deployments) capture of an LLDP frame from an MX60. Among other pieces of information, it indicates the appliance's...

Note: Depending on the model MX, the LLDP port ID may not align with the physical LAN port numbering. Across all MX-Appliances, the port ID will begin at 0 for the first LAN port, then increment based on the number of LAN ports. However, this does not take offsets of the Internet ports into account. For example, an MX65 has Internet ports 1 and 2, and its first LAN port is labeled port 3. Therefore, the LLDP port ID 0 will still be reported for LAN port 3.

MX84s in some configurations will send their LLDP information on VLAN 4095

Legacy Access Points

Legacy access points, such as the OD2, Solar, or other wireless products listed on the End of Life (EOL) page, also support LLDP similarly to the MR Access Points. Please refer to that section for more information.

Note: Not all functionality may be available on EOL devices and can vary by platform.
