Cisco MGM automatically discovers network elements and displays them on the Map Viewer screen. From this screen you can view operational status and navigate to screens that support Cisco MGX 8000 Series CVG configuration and software upgrades.
Cisco MGM organizes MGX 8000 Series CVGs by site. A site contains all gateways that have the same value for the standard SNMP sysLocation object. If a gateway does not have a value set for sysLocation, Cisco MGM includes the gateway under CMGM_Site_default. If a gateway does have a value set for sysLocation, Cisco MGM includes the gateway under the site titled CMGM_Site_<sysLocation value>.
 |
Note A Cisco MGM site remains in the system even if you delete all its gateways. Use Deployment > Delete Objects to remove an empty site. |
To change the system location of a selected object, follow these steps:
Step 2 Click the Viewer button. The MapViewer screen opens.
Step 3 Click the tree of objects to display the list of sites and nodes.
Step 4 Right-click the desired site or node and select Open Object Configuration. The Object Configuration window opens. (See Figure 4-1.)
Step 5 Select the desired object from the Object Types list. The associated object parameters display in the Single Value Attributes tab.
Step 6 Enter the new system location in the sysLocation field, then choose File > Save. The system updates the location for the selected object.
Automatic discovery occurs in two phases:
1. Automatic discovery of Cisco MGX 8000 Series CVGs and associated media gateway controllers in a subnet.
2. Subchassis synchronization of MGX 8000 Series subcomponents.
You initiate automatic discovery from the Cisco MGM GUI by specifying the desired IP address range. Cisco MGM automatically discovers MGX 8000 Series CVGs and media gateway controllers with IP addresses that fall within this range. For more information, see the "Cisco MGM Community String and Security Configuration" section.
When you initiate automatic discovery, Cisco EMF pings each IP address in the given range. If a response is received, Cisco EMF initiates an SNMP GET request for the enterprise object id (OID). If the OID matches any of the predefined Cisco EMF class mappings, an object of that class is created and displayed. If no match is found, the process creates a generic SNMP device under the physical level of the hierarchy. You can't manage these generic devices.
To discover network elements, follow these steps:
Step 2 Log on to Cisco EMF. The Launchpad screen opens.
Step 3 Click the Discovery button. The Discover Network Devices screen opens. (See Figure 4-2.)
Step 4 Configure the discovery parameters:
Step 5 Click Start.
Step 6 At the end of the discovery process, click Close.
Subchassis synchronization searches for entities within a Cisco MGX 8000 Series CVG and displays them on the Cisco MGM user interface. The subchassis synchronization process is automatically invoked after auto discovery. The subchassis synchronization process inspects SNMP MIBs for the following configurable objects:
Cisco MGM uses the read-write community string for subchassis synchronization. You can change the default read-write community string in the cmgmvCtrlUserData.ini file. For more information about the cmgmvCtlrUserData.ini file, refer to "Cisco MGM Server Configuration Files."
When the subchassis synchronization process is complete, Cisco MGM adds the subchassis components to the site hierarchy display. You can expand the hierarchy to display cards and profiles by clicking the + sign next to the Cisco MGX 8000 Series icons. Similarly, you can expand the hierarchy to display lines by clicking the + sign next to each card. A number next to the object indicates the number of contained cards or lines.
You can manually invoke the subchassis synchronization process from the Cisco EMF menu bar. The subchassis discovery process retrieves subchassis component information from each Cisco MGX 8000 Series CVG and displays corresponding objects on the Cisco MGM user interface.
To synchronize subchassis components, follow these steps:
Step 2 Click the Viewer button. The MapViewer screen opens.
Step 3 Click the tree of objects to display the list of sites and nodes.
Step 4 Right-click the desired site or node and select SubChassis Sync Up. The Subchassis Sync Up window opens. (See Figure 4-3.)
Step 5 Select the desired nodes from the list.
Step 6 Click Start.
The system synchronizes the user display with subchassis components.
Periodic subchassis synchronization discovers the subchassis components of each node without user intervention. This background task runs on a fixed interval, once every 24 hours, rather than at a fixed time. Therefore, the time of day when this task runs depends on the last time the Cisco MGM controller was initialized.
Object configuration data for Cisco MGM supported objects are available through the Cisco EMF Object Configuration window. By selecting an object and launching the Object Configuration window, data specific to the selected object is available. Choose the appropriate option from the Object Type list to view the applicable data in the lower portion of the window. Because each type of object is modeled differently in the software, data is available through different object type selections for each type of object. For example, the available object type selections for a VISM card differ from those supporting a AXSM card.
Although the data presented in the Object Configuration window is modifiable, it is not recommended to save changes.
For further information on launching and using the Object Configuration window, see the Cisco Element Management Framework User Guide.
The software download feature facilitates the downloading of runtime and backup boot image files from a Cisco MGM workstation to a device. Depending upon the device type, the image is downloaded either via TFTP (PXM1-based card) or FTP (PXM1-E or PXM45-based cards.) The system reports whether the download was a success or failure; in the case of a failure, detailed information is provided about the failed TFTP or FTP commands. Downloading a software image does not automatically activate it; the selected gateway continues to operate on current software until you perform the upgrade procedure.
|
Note Runtime software image files are saved using the extension ".fw" and boot images are saved using the extension ".bt". |
To download software image files, follow these steps:
Step 2 Click the Viewer button. The Map Viewer screen opens.
Step 3 Click the tree of objects to display the list of sites and nodes.
Step 4 Right-click the icon for the desired site or chassis and select Image Download. The Image Download screen opens. (See Figure 4-4.)
Step 5 Enter the file information shown in Table 4-1.
 |
Caution Cisco MGM does not check for a match between the device and the image file entered. If you select an incorrect type of image for the device, the device does not function properly. Before installing images on your managed devices, check their compatibility by contacting the Cisco Technical Assistance Center. |
Table 4-1 Software Image Download
Step 6 Click Start. An action result dialog appears with status of the image download action for the selected devices. If successful, the software image files are sent via either TFTP or FTP (depending upon the device type) to the appropriate device directory.
|
Note Upon successful download of a PXM image file, another supporting file named ComMat.dat is automatically downloaded to the device as well. |
Step 7 Repeat steps 5 to 6 for other card images.
Step 8 Click Close when finished downloading the desired software images to close the Image Download window.
Once the desired software image files have been downloaded, you must telnet to the device and execute the necessary commands to fully activate the image. For more information on how to activate software image files that have been downloaded to the system, refer to the following documents:
You can back up and restore network card and chassis configurations using the Cisco MGM configuration save and restore feature. Files are saved one level above your <CEMFROOT> directory with the following file naming convention:
<CEMFROOT>/../ConfigData/<IPADDRESS>_<BACKUPID>/<NODENAME>.ZIP
|
Note You can change the default directory by editing the CMGMVConfigSaveDir setting in <CEMFROOT>/config/init/cmgmCtlrUserData.ini. |
The Cisco MGM configuration save function logs on to the selected device, invokes a saveallcnf command to generate the configuration file, and sends a tftp get command to transfer the device configuration file to your Cisco MGM workstation.
To save a device configuration file, follow these steps:
Step 2 Click the Viewer button. The Map Viewer screen opens.
Step 3 Click the tree of objects to display the list of sites and nodes.
Step 4 Right-click the icon for the desired site and click Configuration Save/Restore. The Configuration Save/Restore Dialog window opens. (See Figure 4-5.)
Step 5 Enter the required information. (See Table 4-2.)
