NAME

       APP - Show / manipulate APP TLV configuration

SYNOPSIS

       lldptool -t -i ethx -V APP [-c app]

       lldptool -T -i ethx -V APP [-d] app=prio,sel,pid

DESCRIPTION

       The  APP  TLV is an informational TLV and will advertise the current configured application table. If the
       peer APP TLV and a local APP TLV match the same selector and protocol field the local parameter is used.

ARGUMENTS

       app    Configures a local application data field using the three parameters:  priority  (prio),  selector
              (sel),  and  protocol  (pid).  The  -d option can be provided to remove an entry which matches the
              three parameters.

Theory of Operations

       The APP TLV is an informational TLV for most end stations. It is  not  expected  that  setting  APP  data
       should  be  required.  Peer  data  will  be  processed and added to the application data table by default
       assuming there does not already exist a local entry with matching selector and priority fields.

       By adding APP data to the application table it is  available  for  applications,  eg  iscsid,  to  query.
       Applications  query  for  a  specific  protocol  and selector and may use this data to map traffic to the
       corresponding traffic class.

EXAMPLE & USAGE

       Configure ISCSI application for priority 4 on eth2
              lldptool -T -i eth2 -V APP app=4,2,3260

       Configure FCoE application for priority 3 on eth2
              lldptool -T -i eth2 -V APP app=3,1,35078

       Remove FCoE application for priority 3 on eth2
              lldptool -T -i eth2 -V APP -d app=3,1,35078

       Display locally configured application table on eth2
              lldptool -t -i eth2 -V APP -c app

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