Thread: NIC Bonding 802.3ad troubles

    Default NIC Bonding 802.3ad troubles

    Im having an issue with the bonding with 802.3ad and dss v7. Ive correctly configured my switch for LACP, and it recognizes the LAG and everything seems OK, I created an 802.3ad bonding on the dss server, looks good, and status shows OK. My switch is transmitting to the dss over LAG OK, traffic looks evenly split across the bonded trunk, but I only ever receive from the dss on one network card. Any idea how to correct this?

    Also just a note, that the gateway in the network configuration is always stuck on eth1, I can select the bond0 interface and apply, but it always returns back to eth1.. Not sure that this has anything to do with it?

    Check the tests.log from the log file and check the ifconfig -a section and see if the MAC Addresses are the same.
    Also go to the Console screen and enter CTRL ALT N then change the Gateway there to see if holds.
    All the best,

    Couldn't figure out how to edit a post, but you can see that the server receives evenly the data, but eth1 has done all the transmitting.. I can't use the local console because its off site, any other way to set that gateway from eth1 to bond0 without driving there (and if I recall, the console showed the correct gateway anyway)

    Thanks!
