The Link Layer Discovery Protocol (LLDP) or IEEE 802.1AB is a vendor-neutral Data Link Layer protocol used by network devices for advertising of (announcing) identity, capabilities and interconnections on a IEEE 802 LAN network. The protocol is formally referred to by the IEEE as Station and Media Access Control Connectivity Discovery. Both LLDP snooping and ability to generate and transmit LLDP packets is provided.
Information obtained via CDP and LLDP snooping is available in the UI. Information obtained using LLDP is provided during the adoption process, so the layer 2 device detected by the access point can be used as a criteria in the provisioning policy.
To set a profile's LLDP configuration:
Select Configuration > Profiles > Network.
Expand the Network menu to display its submenu options.
Select Link Layer Discovery Protocol.
Check the Enable LLDP box to enable Link Layer Discovery Protocol on the device.
Refer to the Hold Time field and use the spinner control to define a hold time from 10 - 1800 seconds for transmitted LLDP packets. The default value is 180 seconds.
Refer to the Timer field and use the spinner control to define the interval between 5 - 900 seconds to transmit LLDP packets. The default value is 60 seconds.
Enable Inventory Management Discovery to track and identify inventory attributes including manufacturer, model or software version.
Enable Extended Power via MDI Discovery to provide detailed power information from end points and other connected devices.
Select the OK button to save the changes. Select Reset to revert to the last saved configuration.
