LLDP Configuration

About this task

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/define LLDP configurations:

Procedure

  1. Go to Configuration → Devices.

    The Device Configuration screen displays. This screen lists wireless controllers, service platforms and access points within the managed network.

  2. Select a device from the list displayed.

    The selected device's configuration screen displays.

  3. Expand Profile Overrides → Network and select LLDP.

    The LLDP configuration screen displays.

  4. Set the following LLDP parameters:

    Enable LLDP

    Select this option to enable LLDP on the access point. LLDP is enabled by default When enabled, an access point advertises its identity, capabilities and configuration information to connected peers and learns the same from them.

    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 extended power via MDI discovery TLV in LLDP PDUs. This setting is disabled by default.
  5. Click OK to save the LLDP configuration changes.

    Click Reset to revert to the last saved configuration.
