Example for Performing In-Service Patch Installation

This section provides an example for installing patches without interrupting services.

Networking Requirements

In-service patch installation can be performed on a device if the device performance needs to be optimized without affecting the use of the current system software, and if the device must work uninterruptedly for a long time.

As shown in Figure 1, the performance of Device A needs to be optimized. Huawei has provided a patch file for the customer to install.

Configuration Roadmap

The configuration roadmap is as follows:

Upload a patch to the storage medium of AMB.
Load and run the patch.
Verify the configuration.

Data Preparation

To complete the configuration, you need the following data:

Name of the patch, which is V***R***SPH001.pat in this example
Patch file storage path on the main control board, which is cfcard:/ in this example

Procedure

Upload the patch matching the system software.

# Configure Device A as an FTP server.

<HUAWEI> system-view
[~HUAWEI] sysname DeviceA
[*HUAWEI] commit
[~DeviceA] ftp server enable
Info:  Enabling the FTP server configuration  succeeded. 
[*DeviceA] aaa
[*DeviceA-aaa] local-user user1 password cipher Hello-huawei123
[*DeviceA-aaa] local-user user1 service-type ftp
[*DeviceA-aaa] local-user user1 ftp-directory cfcard:/
[*DeviceA-aaa] commit
[~DeviceA-aaa] quit
[~DeviceA] quit

After the configuration is complete, run the display local-user command to view user information.

<DeviceA> display local-user

# On the PC, configure the binary transmission mode and set c:\temp as the working directory.

The following part uses the Windows system as an example.

Save the uploaded system software to the specified directory (for example, c:\temp).
Choose Start > Run. Enter cmd, and then press Enter
Enter FTP 10.1.1.1. In the user field, enter the user name; in the password field, enter the password.

The following configurations are displayed:

ftp 10.1.1.1
Connect to 10.1.1.1.
220 FTP server ready.
User <10.1.1.1:<none>>:user1
331 Please specify the password.
Password:
230 User logged in.

Specify a directory for the FTP client to store the uploaded files and specify the file transfer mode.

ftp> binary
200 Type set to I.
ftp> lcd c:\temp
Local directory now c:\temp.

# Upload the patch matching the current system software from the PC to Device A.

ftp> put V***R***SPH001.pat
200 Port command okay.
226 Transfer complete.

Load and run the patch.

<DeviceA> patch load V***R***SPH001.pat all run
Info: Operating, please wait for a moment......done.
Info: Succeeded in running the patch.

Verify the configuration.

After the preceding configurations, run the display patch-information command, and you can view patches in the running state on DeviceA.

<DeviceA> display patch-information
Patch Package Name    :cfcard:/V***R***SPH001.PAT
Patch Package Version :V***R***SPH001
Patch Package State   :Running   
Patch Package Run Time:2011-11-07 11:55:01
