  • LACP mode 4 bonding not coming up on RHEL 7

    Posted on

    Hi Experts

    We followed RHEL documentation to configure bonding on RHEL7. However, the interfaces don't pass any traffic, not even ARP. Please advise.

    What does "port state=63" and "port key=13" mean? Bond1 has 10 GBps slave interfaces and has this issue. Bond0 has 1 Gbps slave interfaces and works fine in fault-tolerant mode.

    # cat ifcfg-bond1
    NAME=bond1
    DEVICE=bond1
    BONDING_MASTER=yes
    TYPE=Bond
    ONBOOT=yes
    BOOTPROTO=none
    BONDING_OPTS="mode=4 miimon=100 lacp_rate=1"
    NM_CONTROLLED=no
    
    #  cat /sys/class/net/bond1/bonding/mode
    802.3ad 4
    
    # cat /proc/net/bonding/bond1
