NAME

       LLDP-MED - Show / manipulate MED TLV configurations

SYNOPSIS

       lldptool -t -i ethx -V [ TLV_TYPE ] enableTx

       lldptool -T -i ethx -V [ TLV_TYPE ] enableTx = { yes | no }

       lldptool -T -i ethx -V LLDP-MED devtype = { class1 | class2 | class3 }

       lldptool -t -i ethx -V LLDP-MED devtype

TLV_TYPE : = {LLDP-MED | medCap | medPolicy | medLoc | medPower | medHwRev | medFwRev | medSwRev | medSerNum | medManuf | medModel | medAssetID }

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
