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
