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

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

lldptool -T -i eth2 -V APP app=4,2,3260
lldptool -T -i eth2 -V APP app=3,1,35078
lldptool -T -i eth2 -V APP -d app=3,1,35078
lldptool -t -i eth2 -V APP -c app
lldptool -t -i eth2 -V APP
