NAME

6       APP - Show / manipulate APP TLV configuration
7

SYNOPSIS

9       lldptool -t -i ethx -V APP [-c app]
10
11       lldptool -T -i ethx -V APP [-d] app=prio,sel,pid

DESCRIPTION

15       The APP TLV is an informational TLV and will advertise the current con‐
16       figured application table. If the peer APP TLV  and  a  local  APP  TLV
17       match the same selector and protocol field the local parameter is used.

ARGUMENTS

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

Theory of Operations

28       The APP TLV is an informational TLV for most end stations.  It  is  not
29       expected  that  setting  APP data should be required. Peer data will be
30       processed and added to the application data table by  default  assuming
31       there  does  not already exist a local entry with matching selector and
32       priority fields.
33
34       By adding APP data to the application table it is available for  appli‐
35       cations,  eg iscsid, to query. Applications query for a specific proto‐
36       col and selector and may use this data to map  traffic  to  the  corre‐
37       sponding traffic class.
