lldp

Profile Config Commands

Enables LLDP on this profile and configures LLDP settings

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.

Supported on the following devices:

Syntax

lldp [holdtime|med-tlv-select|run|timer]
lldp [holdtime <10-1800>|run|timer <5-900>]
lldp med-tlv-select [inventory-management|power-management {auto}]

Parameters

lldp [holdtime <10-1800>|run|timer <5-900>]
lldp Enables LLDP on this profile and configures LLDP settings
holdtime <10-1800> Sets the holdtime for transmitted LLDP PDUs. This command specifies the time a receiving device holds information before discarding.
  • <10-1800> – Specify a holdtime from 10 - 1800 seconds. The default is 180 seconds.
run Enables LLDP on this profile
timer <5-900> Sets the transmit interval. This command specifies the transmission frequency of LLDP updates in seconds.
  • <5-900> – Specify transmit interval from 5 - 900 seconds. The default is 60 seconds.
 
lldp med-tlv-select [inventory-management|power-management {auto}]
lldp Enables LLDP on this profile and configures LLDP settings
med-tlv-select [inventory-management| power-management {auto}] Provides additional media endpoint device TLVs to enable inventory and power management discovery. Specifies the LLDP MED TLVs to send or receive.
  • inventory-management – Enables inventory management discovery. Allows an endpoint to convey detailed inventory information about itself. This information includes details, such as manufacturer, model, and software version, etc. This option is enabled by default.
  • power-management auto – Enables extended power via MDI discovery. Allows endpoints to convey power information, such as how the device is powered, power priority, etc.
    • auto – Optional. Assigns default value based on device type
