Managing networks with imc BIMS CPE devices in a WAN feature large quantity and dynamic IP addresses. Therefore, imc BIMS uses the OUI and serial number to uniquely identity a CPE device. To manage a CPE device in a WAN with imc BIMS, first complete these operations in the imc BIMS system: Configure system settings, add CPE authentication users, and add the CPE device. Then, log in to the CPE device, configure CPE WAN Management Protocol (CWMP) parameters, which must be the same as those configured in imc BIMS. After the CPE device configuration is complete, and the CPE device actively accesses imc BIMS, imc BIMS can manage it. You can manage the actively connected devices by their privilege, back up their configurations, and deploy the configuration file and device software for them. The following sections describe a typical imc BIMS configuration procedure. Log in to imc BIMS as an admin, and then perform the following configurations. System settings System settings needed include default polling time, periodic inform interval, device access parameters, CPE device adding policy, and common password. imc BIMS provides default settings for some parameters, and you can modify them as needed. Log in to imc BIMS, and then click the System tab to enter the page shown in Figure 6. Figure 6 System Configuration On the page, click System Settings in the System Configuration area to enter the System Settings page. 6

Figure 7 System Settings The following describes the system settings: File Server Parameters: Set the file server status, enabled or disabled. In a NAT environment, you can enable the file server function to perform device backup and deployment operations. When the file server is enabled, the IP address of the file server must be configured. Default Polling Interval: Interval for imc BIMS to poll the connection status of devices. If any device is found unreachable, imc BIMS changes the status of the device. Periodic Inform Interval: Default interval for the device to access imc BIMS. The device actively reports its current status when accessing imc BIMS. Device Access Parameters: Username and password used by imc BIMS to connect to a CPE device. imc BIMS can actively connect to the device only if the username and password are the same as those for the CPE to access imc BIMS. A newly added CPE device needs to use the username and password when accessing imc BIMS. CPE Device Adding Policy: Specifies whether to automatically add CPE devices that actively access imc BIMS Common Password: If the username and password used by imc BIMS to connect to a CPE device are not the same as those for the CPE to access imc BIMS, common password authentication is enabled. The common password is bims by default, and you can change it as needed. 7

Click OK to complete your configuration. Adding CPE authentication users CPE authentication user information corresponds to the username and password of the Auto-Configuration Server (ACS), namely, the imc BIMS server. imc BIMS provides a default CPE authentication user, and you can add CPE authentication users as needed. Click the System tab, and select CPE Authentication User in the navigation tree to enter the page for CPE authentication user management, as shown in Figure 8. Figure 8 CPE Authentication User Click Add to enter the Add CPE Authentication User page. Figure 9 Add CPE Authentication User Type the username, password, and description. Then click OK. Add CPE devices CPE devices can be added to imc BIMS either automatically or manually. Automatically On the System Settings page, select Yes from the Add CPE Device Automatically drop-down list. An automatically added CPE device is named as OUI + serial ID. 8

Manually The status of a manually added CPE device is unknown, or in other words, imc BIMS considers the device a virtual device before the device accesses imc BIMS. When the device accesses imc BIMS and passes authentication, imc BIMS updates the status of the device. You can define a name for a CPE device when adding the device to imc BIMS. Click the Resource tab, and select Add Device in the navigation tree to enter the Add Device page. Figure 10 Add Device To add a device to imc BIMS, input the following information: Device Name: Name of the device to be added. OUI: OUI of the vendor, which must be valid. Serial ID: Serial ID of the device. The combination of OUI and serial ID uniquely identifies a device. Device Group: Group to which a device belongs after it is added to imc BIMS. By default, a device does not belong to any group. Click OK after your configuration. Configuring CWMP parameters of a CPE To enable a CPE device to communicate with imc BIMS, you need to configure the following CWMP parameters for the device: ACS URL: URL that the CPE uses to access the imc BIMS server. ACS username and password: Username and password used by the CPE to access the imc BIMS server. The username and password should be the same as those configured in the imc BIMS system settings. CWMP status The following shows an example: # Enter CWMP view. [H3C] cwmp 9

# Configure the host name or IP address (http://10.153.129.5 in this example) and port of the imc BIMS server. The default port number for the CPE to access the imc BIMS server is 9090. [H3C-cwmp] cwmp acs url http://10.153.129.5:9090 # Configure the username used by the CPE to access the imc BIMS server. [H3C-cwmp] cwmp acs username vicky # Configure the password used by the CPE device to access the imc BIMS server. If the common password is disabled, a corresponding CPE authentication user must exist and the password must match to enable the CPE device to access imc BIMS. [H3C-cwmp] cwmp acs password 12345 # Configure the username used by imc BIMS to access the CPE. The username must be the same as that configured in Device Access Parameters. [H3C-cwmp] cwmp cpe username bims # Configure the password used by imc BIMS to access the CPE. The password must be the same as that configured in Device Access Parameters. [H3C-cwmp] cwmp cpe password imcbims # Configure the outgoing interface on the CPE to connect to imc BIMS.

When some commands configured in the Execute Command After Export field of the data export function were executed, the CPU utilization kept high for a long time. Why? Solution: Make sure that the commands have no GUIs included, are executed at the background, and can automatically exit after execution. When imc BIMS runs for a period of time, the memory utilization becomes extremely high and cannot recover. What shall I do? Solution: You can solve the problem by changing the maximum buffer size for the SQL server. Do the following: Run the setsqlservermaxmem.bat script in the installation directory\client\bin directory. The parameters are as follows: -server IP address: IP address of the server. This is an optional parameter. By default, the IP address of the current PC is displayed. -sapwd password: Password of the sa user. This is a required parameter. -maxmem maxmem: Maximum buffer size to change, in MB. This is an optional parameter. By default, the current buffer size is displayed. Suppose that the installation directory is G:\Program Files\iMC. To set the buffer size of the database to 1024 MB, run the setsqlservermaxmem -server 127.0.0.1 -sapwd sa -maxmem 1024 command in the G:\Program Files\iMC\client\bin directory. Note that: The buffer size in actual use may be greater than that you configured because the database itself uses some buffer. The preceding configurations become effective after you reboot the database. Can I modify the system time when imc BIMS is running? Solution: You are not recommended to manually modify the system time when imc BIMS is running. If you do so, data confusion or process errors may occur. If imc BIMS process errors are caused by system time modification, restart imc BIMS-related processes (including the Intelligent Deployment Monitoring Agent and the H3C imc Server services). When I try to log in to imc BIMS through the management PC, the system displays an insufficient system resource error. What shall I do? Solution: You can solve the problem by changing the Java heap size of the system. Do the following: The Java heap size is in the range of 256 to 1024 MB. You can change the Java heap size to 1024 MB, for example in a 32-bit operating system. Table 4 lists different Java heap sizes specific to the number of online operators in a 64-bit operating system.
