Hello community,
I Have a strange problem with network traffic over LACP after some time. When I configured the LACP and the VLANs everything worked fine, but after some hours some Host just can't reach the FreeNAS Server any more, the FreeNAS server can't reach them too. other systems on the same network, also same VLAN do still work! There is just no more response any more, it is like for one way the packets are just silently dropped.
My setup:
OS: FreeNAS 11.3-U2
2x Intel x520-da2 (I use 1 port (10G) from each card)
Switch: Juniper Ex4600 (JUNOS 17.3)
on FreeNAS
lagg0: 2 10G ports, mtu 9000
vlan33: vlan tag:33, IPv4 Address. / parent interface lagg0
vlan44: vlan tag:44, IPv6 Address (fd00::1/64). / parent interface lagg0
on the Switch:
mtu 9200;
aggregated-ether-options {
minimum-links 1;
lacp {
active;
}
}
unit 0 {
family ethernet-switching {
interface-mode trunk;
vlan {
members [ VM-Storage_44 SERVERS_PROD_33 ];
}
}
}
I have been looking into the Intel Nic drivers and today LACP hashing algorithm. But can't find the problem...
any Ideas.
thanks in advance
