Profile Overrides - LLDP

The LLDP (Link Layer Discovery Protocol) provides a standard way for a controller or access point to advertise information about themselves to networked neighbors and store information they discover from their peers.

LLDP is neighbor discovery protocol that defines a method for network access devices using Ethernet connectivity to advertise information about them to peer devices on the same physical LAN and store information about the network. It allows a device to learn higher layer management and connection endpoint information from adjacent devices.

Using LLDP, an access point is able to advertise its own identification, capabilities and media-specific configuration information and learn the same information from connected peer devices.

LLDP information is sent in an Ethernet frame at a fixed interval. Each frame contains one m LLDP PDU(Link Layer Discovery Protocol Data Unit). A single LLDP PDU is transmitted in a single 802.3 Ethernet frame.

To override the access point profile's LLDP configuration:

  1. Go to Configuration → Devices → Device Overrides.

    The Device Overrides screen displays. This screen lists devices within the managed network.

  2. Select an access point.

    The selected access point's configuration menu displays.

  3. Expand Profile Overrides → Network and select Link Layer Discovery Protocol (LLDP).

    The LLDP configuration screen displays.

  4. Select the Enable LLDP option, and set the following parameters:

    Hold Time

    Use the spinner control to set the hold time (in seconds) for transmitted LLDP PDUs. Set a value from 10 - 1,800. The default hold time is 180 seconds.

    Timer

    Set the interval used to transmit LLDP PDUs. Define an interval from 5 - 900 seconds. The default setting is 60 seconds.

    Inventory Management Discovery

    Select this option to include LLPD-MED inventory management discovery TLV in LLDP PDUs. This setting is enabled by default.

    Extended Power via MDI Discovery

    Select this option to include LLPD-MED (LLDP - Media Endpoint Discovery) extended power via MDI (Media Dependent Interface) discovery TLV in LLDP PDUs. This setting is disabled by default.
  5. Select OK to save the LLDP configuration changes.

    Select Reset to revert to the last saved configuration.
