LLDP

Link Layer Discovery Protocol (LLDP) is defined by the IEEE 802.1AB standard and allows the UAP to advertise information about itself such as the system name, system capabilities, and power requirements. This information can help you identify system topology and detect bad configurations on the LAN. The AP also supports the Link Layer Discovery Protocol for Media Endpoint Devices (LLDP-MED), which standardizes additional information elements that devices can pass to each other to improve network management.

1. To configure LLDP settings, select LAN > LLDP in the navigation area.
2. Configure the following parameters:
• LLDP Mode—The administrative mode of LLDP on the AP. When LLDP is enabled, the AP transmits LLDP Protocol Data Units to neighbor devices.
• TX Interval—The number of seconds between LLDP message transmissions. The valid range is 5 to 32768 seconds. The default value is 30 seconds.
• POE Priority—The priority level transmitted by the AP in the Extended Power information element. The PoE priority level helps the Power Sourcing Equipment (PSE), such as a switch, determine which powered devices should be given priority in power allocation when the PSE does not have enough capacity to supply power to all connected devices. The PoE priority can be one of the following:
• Critical
• High
• Low
• Unknown
3. Click Save. The settings are saved to the system.
