I have a LACP setup on a Intel 82580 4 Port PCIe setup and an Unifi Switch.
Everything works for a while, sometimes a few days and sometimes a few weeks. At one point though it will just stop working. Doing a port monitor at the switch shows no LACP traffic going back and forth. Unplugging the interface cables does not get any negotiation going either.
Restarting the FreeNAS server brings everything back into a good state.
When my lagg interface is in a bad state it looks like this:
lagg0: flags=8902<BROADCAST,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500
description: lagg0
options=2400b9<RXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,VLAN_HWTSO,RXCSUM_IPV6>
ether ac:16:2d:9b:f2:01
inet 192.168.253.66 netmask 0xffffffc0 broadcast 192.168.253.127
nd6 options=9<PERFORMNUD,IFDISABLED>
media: Ethernet autoselect
status: active
groups: lagg
laggproto lacp lagghash l2,l3,l4
laggport: igb1 flags=0<>
laggport: igb2 flags=0<>
laggport: igb3 flags=0<>
The laggport flags are the indicator that they are empty.
What troubleshooting can I do from the CLI? I cannot seem to restart networking nor find the configuration for hte laggport outside of the GUI. I think those are the 2 best things to start looking at.
Any advice? Thanks in advance.
