I configured a lacp (lagg0) with two 10G-Intel NICs. Latter I created 2 VLA=
N over lagg0.
When trying to ping from host vlan to any other hosts doesn't work.=20
I ran tcpdump on each interface, ix[0|1], lagg0 and vlan[52|908].
- On each physical interface I see packets coming from network. I can see m=
ainly broadcasts, correctly tagged, etc.
- On lagg0 interface I also see packets coming from network. When running t=
cpdump on vlanXX I only can see ARP requests from localhost.
It's seems packets doesn't "flow" from/to vnic and lagg.
Inbound=20
( network ) --> [ix0] --> [lagg0] ---X---> [vlan52]
( network ) --> [ix0] --> [lagg0] ---X---> [vlan52]
Outbound=20
( network ) <-- [ix0] <-- [lagg0] <---X--- [vlan52]
( network ) <-- [ix0] <-- [lagg0] <---X--- [vlan52]
Any idea what's wrong??
