Supported LLDP Attributes
The Link Layer Discovery Protocol (LLDP) is a vendor-neutral Layer 2 protocol that allows a network device (for example, a Ruckus AP) to advertise its identity and capabilities on the local network.
LLDP information is sent by devices from each of their interfaces at a fixed interval (default is 30 seconds), in the form of an Ethernet frame. Each LLDP Ethernet frame contains a sequence of type-length-value (TLV) structures starting with Chassis ID, Port ID and Time to Live (TTL) TLV. Table 2 lists the LLDP attributes supported by the controller.

Each LLDP Ethernet frame contains a sequence of type-length-value (TLV) structures starting with Chassis ID, Port ID and Time to Live (TTL) TLV.The follwoing table lists the LLDP attributes supported by the controller.
| Attribute (TLV) | Description |
|---|---|
| Chassis ID | Indicates the MAC address of the AP’s br0 interface |
| Port ID | Identifies the port from which the LLDP packet was sent |
| Time to Live | Same as LLDP Hold Time. Indicates the length of time (in seconds) that a receiving device will hold the LLDP information sent by the selected AP model before discarding it. The default value is 120 seconds. |
| System Name | Indicates the name assigned to the AP. The default name of Ruckus APs is RuckusAP. |
| System Description | Indicates the AP model plus software version |
| System Capabilities | Indicates the AP’s capabilities (Bridge, WLAN AP, Router, Docsis), and which capabilities are enabled |
| Management Address | Indicates the management IP address of the AP |
| Port Description | Indicates the description of the port in alphanumeric format |
