  • NIC Bonding 802.3 AD

    Posted on

    Would like to ask for your kind expertise please. Currently one of our servers is configure to have a bond of 802.3AD for ports eno1 and eno2. What we are expecting is that the traffic will flow for those ports but it doesn't work.

    Actual Traffic flow via sar - n DEV 1 command

    Here are the ports equivalent to the connected ports on switch

    GigabitEthernet 0/0/8 = eno1
    GigabitEthernet 0/0/17 = eno2
