How Can I Change the IP Addresses of UDS Planes?

1.Start the UDS Configuration Tool.
2.Choose File > Modify.
The Open dialog box is displayed.

3.Select the original project design file or the original network configuration file, such as UDS_V100R002C01.uds or UDSConfig.xml, and click Open.
4.Click Design Data Network.
5.Click Redesign.
The Network Design Wizard dialog box is displayed.

6.Follow the wizard instructions to change the IP addresses of the management plane or the service plane.
7.Click Export Project and select all options to export the new network configuration file to a local computer.

NOTICE:
If you also change the virtual local area network (VLAN) information about the management plane or the service plane when using the UDS Configuration Tool to change plane IP addresses, modify switch configurations accordingly to enable switch ports for new VLANs before proceeding with the following steps.
If no VLAN information is changed, keep switch configurations unchanged and proceed with the following steps.

8.Logging In to the DeviceManager as user admin.
9.In the navigation bar on the right, click .
The Maintenance page is displayed.

10.Click Change IP Address.
Wizard for Changing IP Address is displayed.

11.Follow the wizard instructions to import the new network design file.
A dialog box is displayed stating Succeeded in changing the IP addresses.

12.Use PuTTY to log in to the active OMS.

Log in as user opadmin using the OMS floating management IP address. Then, run the su - root command to switch to the root account.


13.Run the sh command to check whether any bussinessfloatip resource monitored by the POE HA is in a normal state.

sh /opt/obs/service/poe/ha/module/hacom/script/status_ha.shThe command output is as follows:

Check whether any ResHAStatus of resource bussinessfloatip is Exception.

If yes, go to Step 14.
If no, no further action is required.

14.Clear the bussinessfloatip resource in abnormal state.

/opt/obs/service/poe/ha/module/hacom/tools/ha_client_tool --ip=127.0.0.1 --port=61807 --clearrmfault --name=bussinessfloatip
15.(Optional) Change the value in /etc/resolv.conf to the customer-provided DNS server IP address.

NOTE:
If the UDS works in the single-DC scenario, you need to change the value in /etc/resolv.conf to the customer-provided DNS server IP address after changing the service plane IP address.


a.Use PuTTY to log in to OMS01.

Log in as user opadmin using the management IP address of OMS01. Then, run the su - root command to switch to the root account.


b.Change the value of nameserver in /etc/resolv.conf to the customer-provided DNS server IP address.

For example:
nameserver 192.168.182.3
nameserver 192.168.182.4
options timeout:1 attempts:5
c.Use PuTTY to log in to OMS02.

Log in as user opadmin using the management IP address of OMS02. Then, run the su - root command to switch to the root account.


d.Change the value of nameserver in /etc/resolv.conf to the customer-provided DNS server IP address.

For example:
nameserver 192.168.182.3
nameserver 192.168.182.4
options timeout:1 attempts:5
16.(Optional) Log in to the DeviceManager and clear the alarm about the abnormal access switch port.

After the IP address is changed, the switch may report an Access Switch Port Link Is Abnormal alarm. Because the monitoring process is not started yet, the message about the recovery of the switch port fails to be received. Therefore, you need to manually clear the Access Switch Port Link Is Abnormal alarm.

For details about how to clear the alarm, refer to the online help on the interface of the DeviceManager.
