How to configure the interface to only use certain NIC

Solution Unverified - Updated -

Issue

  • There are 2 NICs with the same IP address, but one NIC is down.

    # ip address show
    ...
    3: ens9: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
        link/ether 52:54:00:ee:c6:16 brd ff:ff:ff:ff:ff:ff
        inet 192.168.1.1/24 scope global ens9
           valid_lft forever preferred_lft forever
    4: ens10: <BROADCAST,MULTICAST> mtu 1500 qdisc fq_codel state DOWN group default qlen 1000
        link/ether 52:54:00:52:78:ca brd ff:ff:ff:ff:ff:ff
        inet 192.168.1.1/24 scope global ens10
           valid_lft forever preferred_lft forever
    

    And my standalone.xml (or host.xml in domain mode) has <up/> criteria to identify a NIC uniquely.

        <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 my server is not able to start with the following errors.

    # $JBOSS_HOME/bin/standalone.sh -b 192.168.1.1 -bmanagement=192.168.1.1
