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. The following
table lists the LLDP attributes supported by the controller.
LLDP Attributes
| 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 |
