#17274: lldpd not work
---------------------------+----------------------------------
Reporter: keyman0413@… | Owner: developers
Type: defect | Status: new
Priority: normal | Milestone: Chaos Calmer (trunk)
Component: packages | Version: Trunk
Resolution: | Keywords: lldpd
---------------------------+----------------------------------
Comment (by anonymous):
I think I found what the problem is. The current way of running lldpd
(created by the lldpd init script) is more or less:
lldpd -I loop -I br-lan -M 4
This result in
2014-09-30T14:25:29 [ DBG/interfaces] driver for eth0 is `ag71xx`
2014-09-30T14:25:29 [ DBG/interfaces] driver for eth1 is `ag71xx`

2014-09-30T14:25:29 [ DBG/interfaces] blacklist wlan0
If I run instead:
lldpd -I eth0,wlan0
the result is:
2014-09-30T14:27:08 [ DBG/interfaces] driver for eth0 is `ag71xx`

So (I may be wrong):
1) br-lan is discarded because it's a bridge
2) adding multiple interfaces must be done by a single -I and multiple
interfaces separated by comma. A new -I will reset the list.
The issue must be solved in the rc script, I think, here:
for iface in $ifaces; do
local ifname=""
if network_get_device ifname "$iface" || [ -e
"/sys/class/net/$iface" ]; then
append args "-I ${ifname:-$iface}"
fi
done
