(7.1.0) Network interface selection criteria is not working for a duplicate IP addresses but one is down

XMLWordPrintable

    • Hide

      Suppose 2 NICs are added (by virt-manager) and recognised as "ens9" and "ens10" respectively. These need to be umanamged by NetworkManager. Then asign the same IP address and disable "ens10".

      # nmcli device set ens9 managed no
# ip addr add 192.168.1.1/24 dev ens9 
(Repeat the same for "ens10".)
# ip link set ens10 down

      In the standalone.xml, there are <up/> criterion which is sufficient to identify a unique NIC under the environment described above.

          <interfaces>
        <interface name="management">
            <up/>
            <inet-address value="${jboss.bind.address.management:127.0.0.1}"/>
        </interface>
        <interface name="public">
            <up/>
            <inet-address value="${jboss.bind.address:127.0.0.1}"/>
        </interface>
    </interfaces>

      But it says "ambiguous". WildFly 10.1.0.Final doesn't show this error.
