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

       enableTx
	      Enables the TLV to be transmitted

       devtype
	      Set or query the class type of the device.

TLV_TYPE
       List of supported TLV specifiers applicable to Media Endpoint Devices.

       LLDP-MED
	      apply arguments to all supported MED TLVs.

       medCAP LLDP-MED Capabilities TLV

       medPolicy
	      LLDP-MED Network Policy TLV

       medLoc LLDP-MED Location TLV

       medPower
	      LLDP-MED Extended Power-via-MDI TLV

       medHwRev
	      LLDP-MED Hardware Revision TLV

       medFwRev
	      LLDP-MED Firmware Revision TLV

       medSwRev
	      LLDP-MED Software Revision TLV

       medSerNum
	      LLDP-MED Serial Number TLV

       medManuf
	      LLDP-MED Manufacturer Name TL

       medModel
	      LLDP-MED Model Name TLV

       medAssetID
	      LLDP-MED Asset ID TLV

EXAMPLE &; USAGE
       Enable class1 MED device on eth2
	      lldptool -T -i eth2 -V LLDP-MED enableTx=yes devtype=class1

       Query class type of MED on eth2
	      lldptool -t -i eth2 -V LLDP-MED -c devtype

       Query transmit state of medPolicy on device eth2
	      lldptool -t -i eth2 -V medPolicy -c enableTx

NAME

       PFC - Show / manipulate PFC TLV configuration

SYNOPSIS

       lldptool -t -i ethx -V PFC { willing | enabled | delay | numtcs }

       lldptool -T -i ethx -V PFC <-c CONFIG_ARG ...>

	   CONFIG_ARG :=

	    enableTx = {yes|no} |

	    willing = {0|1} |

	    enabled = [0..7],[0..7],... |

	    delay = integer

DESCRIPTION

       The PFC TLV is used to display and set current PFC TLV attributes.

ARGUMENTS

       enableTx
	      Enable the PFC TLV to be transmitted in the LLDP PDU for the specified interface.

       willing
	      Display  or  set willing attribute. If set and peer TLV is received the peer PFC attributes will be used. If cleared locally config-
	      ured attributes are used.

       enabled
	      Display or set priorities with PFC enabled. The set attribute takes a comma separated list of priorities to enable.

       delay  Display or set delay attribute used to configure PFC thresholds in hardware buffers. If PFC is enabled and  frames  continue  to	be
	      dropped due to full hardware buffers increasing this value may help.

Theory of Operations
       The  PFC TLV uses Symmetric attribute passing meaning the attributes used will depend on the willing bit. If the willing bit is enabled and
       a peer TLV is received the peers attributes will be used. If the willing bit is set to 0 the local attributes should be used. When both the
       peer and local configuration are willing a tie breaking scheme is used. For more detailed coverage see the specification.

EXAMPLE &; USAGE
       Enable PFC for priorities 1, 2, and 4 on eth2
	      lldptool -T -i eth2 -V PFC enabled=1,2,4

       Display priorities enabled for PFC on eth2
	      lldptool -t -i eth2 -V PFC -c enabled

       Display last transmitted PFC TLV on eth2
	      lldptool -t -i eth2 -V PFC
