APP - Show / manipulate APP TLV configuration
lldptool -t -i ethx -V APP [-c app] lldptool -T -i ethx -V APP [-d] app=prio,sel,pid
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.
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

Currently changing the default priority is not supported by default it is set to zero.
