Description

The LLDP-MED extensions support the Link Layer Discovery Protocol for Media Endpoint Devices defined in the ANSI/TIA-1057-2006 document. Each TLV can be configured as a class1 , class2 or class3 device. Class I devices are the most basic class of Endpoint Device, Class II devices support media stream capabilities and Class III devices directly support end users of the IP communication system. See ANS-TIA-1057 for clarification of class types.

Arguments

enableTx: Enables the TLV to be transmitted
devtype: Set or query the class type of the device.
