# Permissions
A normal user has to be member of the _lldpd group in order to run lldpcli.
## Notes on lldpd_flags
Though lldpd_flags is not required to launch lldpd, remember that without
a specified "-I" option lldpd will be listening on _all_ physical interfaces.
Short examples:
* Listen only on em0 and enable CDP:
lldpd_flags="-I em0 -c"
* Listen on all interfaces, except em0:
lldpd_flags="-I *,!em0"
A whitelisted interface beats a blacklisted interface which beats a simple
matched interface. See lldpd(8), which contains the complete documentation.
## Compatibility
This port should work equally well on both FreeBSD and DragonFly BSD, though
the later might be a bit less regularly tested.
