Impact on the System

Messages of the services mapping the floating IP addresses in the file cannot be normally forwarded by HAProxy.

Possible Causes

  • The involved floating IP address and the HAProxy node IP address are not in the same network segment.
  • The involved floating IP address is configured only on one HAProxy node and not configured on another HAProxy node.


  1. Log in to ManageOne Maintenance Portal using a browser.

    • URL: https://Address for accessing the homepage of ManageOne Maintenance Portal:31943, for example,
    • Default username: admin; default password: Huawei12#$

  2. On the menu bar in the upper part of the page, choose Alarms > Current Alarms.
  3. In the alarm list, locate the alarm to be handled, and click on the left of the alarm. The Details page is displayed.
  4. Choose Location Info, obtain the host IP address, that is, the IP address of the node where the alarm is generated.
  5. Use PuTTY to log in to the VM in 4.

    The default username is ulb. The default password is cnp200@HW.

  6. Run the following command to disable user logout upon timeout:


  7. Run the following command to switch to the root user:

    sudo su - root

    The default username is root. The default password is Cloud12#$.

  8. Run the following command to obtain the configured floating IP address:

    cat /home/elb/keepalived/etc/keepalived/keepalived.conf

    Similar information to the following is displayed, record the IP address in virtual_ipaddress:

    ! Configuration File for keepalived
       vrrp_script chk_http_port {
       script "/home/elb/keepalived/script/"interval 2weight 20
        vrrp_instance VI_1 {
        state BACKUP
        interface eth0
        virtual_router_id 162
        priority 100
        advert_int 1
        virtual_ipaddress {
             IP address
       track_script {
        notify_master "/home/elb/keepalived/script/ master"
        notify_backup "/home/elb/keepalived/script/ backup"

  9. Run the following command to check whether the floating IP address is the same as that obtained in 8:

    ip a | grep global | grep inet

    • If yes, contact technical support for assistance.
    • If no, assign the floating IP address again.
