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 proto- col 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 SOURCE

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

lldptool(8) Linux lldptool(8) NAME
PFC - Show / manipulate PFC TLV configuration SYNOPSIS
lldptool -t -i ethx -V PFC { willing | enabled | delay | numtcs } lldptool -T -i ethx -V PFC <-c CONFIG_ARG ...> CONFIG_ARG := enableTx = {yes|no} | willing = {0|1} | enabled = [0..7],[0..7],... | delay = integer DESCRIPTION
The PFC TLV is used to display and set current PFC TLV attributes. ARGUMENTS
enableTx Enable the PFC TLV to be transmitted in the LLDP PDU for the specified interface. willing Display or set willing attribute. If set and peer TLV is received the peer PFC attributes will be used. If cleared locally config- ured attributes are used. enabled Display or set priorities with PFC enabled. The set attribute takes a comma separated list of priorities to enable. delay Display or set delay attribute used to configure PFC thresholds in hardware buffers. If PFC is enabled and frames continue to be dropped due to full hardware buffers increasing this value may help. Theory of Operations The PFC TLV uses Symmetric attribute passing meaning the attributes used will depend on the willing bit. If the willing bit is enabled and a peer TLV is received the peers attributes will be used. If the willing bit is set to 0 the local attributes should be used. When both the peer and local configuration are willing a tie breaking scheme is used. For more detailed coverage see the specification. EXAMPLE &; USAGE Enable PFC for priorities 1, 2, and 4 on eth2 lldptool -T -i eth2 -V PFC enabled=1,2,4 Display priorities enabled for PFC on eth2 lldptool -t -i eth2 -V PFC -c enabled Display last transmitted PFC TLV on eth2 lldptool -t -i eth2 -V PFC SOURCE
