Purpose of this charm is to install and configure LLDP daemon (lldpd). LLDP is used by network administrators to detect how machines are connected to switches and routers.
Start by installing the lldpd charm and relating it to another application, e.g.
juju deploy ubuntu juju deploy lldpd
juju integrate lldpd ubuntu
Being a subordinate charm it needs to be related to an application running on physical machine, in the above case the Ubuntu charm.
By scaling your application, subordinate charm will get installed automatically.
Deploying LLDP to an LXD container or virtual machine may not work as expected due to network bridges for virtual infrastructure not passing through LLDP frames.
By default, LLDPd will listen on all interfaces. The interfaces-regex option selects which interfaces LLDPd listens on and sends discovery frames from. The systemid-from-interface option selects which interfaces LLDPd considers when computing the chassis ID.
One additional option, i40e-lldp-stop, is included because some Intel NICs block user-space LLDP generated data and instead broadcast their own. By setting this option to True (default), NIC's built-in LLDP daemon will be disabled, if such a NIC has been discovered on the system.
CDP, SONMP, and EDP support is disabled by default. The cdp-mode option provides automatic peer-driven operation, modes that force CDPv1 or CDPv2, and peer-driven or forced CDPv2-only operation. The sonmp-mode and edp-mode options can enable or force their respective protocols.
