lldptool(8) Linux lldptool(8)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 con‐
figured 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 param‐
eters 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 appli‐
cations, eg iscsid, to query. Applications query for a specific proto‐
col and selector and may use this data to map traffic to the corre‐
sponding 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

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