Group Settings

    This settings allows you to created various different kinds of groups based on device, interface, IP address etc for reporting purpose in NetFlow Analyzer.

    Options available in Group Settings:

    Setting Description
    Device Group Device Group allows you to create Device Group in NetFlow Analyzer to allows access to various diff users.
    Interface Group  Interface Groups allows you to create Interface groups in NetFlow Analyzer for reporting purpose and allowing access to different user.
    IP Group Allows you to create groups based on IP address for reporting.
    Application Group Allows you to create groups based on applications discovered in NetFlow Analyzer. 
    DSCP Group Allows you to create groups based on DSCP codes discovered in NetFlow Analyzer. 

    Device Group

    NetFlow Analyzer lets you create device groups, which consist of a set of routers. A device group can contain any number of routers, and a router can belong to any number of device groups.

    The Device Group Management option lets you create, manage, and delete device groups. Initially, when no device groups have been created, you will see a message that lets you start creating device groups.

    Note The options visible under the Admin Operations menu depend on the user level you have logged in as. Look up User Management to know more about user levels and the respective administrative operations allowed.

    Creating a Device Group

    Follow the steps below to create a new device group:

    1. Click the Add button to create a new device group
    2. Enter a unique name to identify the device group. The same name is displayed in the Device Group menu on the left, and will be listed under Available device groups when managing a user.
    3. Use the Device Group Description box to enter useful information about the device group

    4. Select the routers needed for this device group from the list of available routers displayed

    Once all values have been entered, click the Save button to create this device group and begin generating traffic reports for the same.

     

    Managing a Device Group

    Click on an existing device group to modify its properties. You can change all properties of the device group except its name. Once you have made changes to the properties of this device group, click the Save button to save your changes. 

    Select a device group and click the Delete button   under Actions to delete the device group. When a device group is deleted, it is removed from the Device Group List and the Device Group menu. All users assigned to this device group will not see this device group on their Dashboard.

     

    Interface Group

    Interface Group allows you to combine interfaces in order to monitor traffic. This can be useful for grouping multiple sub-interfaces into a single logical entity.Follow the steps below to create a new interface group:

    1. Click the Interface Group tab next to the Device Group tab
    2. Enter a name to identify the interface group in the Interface Group Name box .
    3. Use the Interface group speed box to enter the speed limit for the interface group

    4. Select the routers needed and the interfaces under them for this interface group. By selecting a router ,by default, all interfaces are selected. You can selectively unselect the unwanted interfaces from the list.
    5. Click on Add to save the changes. 

    The Interface group that is created is listed in the Dashboard view in the "Interface View" tab.The Interface group name, the In-Traffic & Out-Traffic for the last 1 hour can be seen in it.By clicking on the interface group name it is possible to further drill down to view further details. To delete a particular interface group select the interface group and click on delete

    Modifying an interface group

    You can modify any interface group, later, by selecting the particular interface group to be modified and clicking on the "Modify" tab.

    IP Group

    1. Navigate to the Settings option in NetFlow Analyzer UI.
    2. Click on NetFlow listed in the top menu bar.
    3. Navigate to the Group Settings option available in the left menu bar and select IPGroups.
    4. Click on Add button available on that page and make the selection as required. .
    5. Select the routers needed and the interfaces under them for this interface group. By selecting a router ,by default, all interfaces are selected. You can selectively unselect the unwanted interfaces from the list.
    6. Use the IP group speed box to enter the speed limit for the IP group
    7. Click on Add to save the changes.
    Field Description
    IP Group Name Enter a unique name to identify this IP group
    IP Group Description

    Enter descriptive information for this IP group to help other operators understand why it was created.

    IP Group Based on Select whether you want to define this IP group based on IP address, DSCP names or port-protocol or the combination of any of the three.
    Specify IP/IP Range/Network Select the IP address, address range, or network that this IP group is based on. Use the Add More option to add additional specifications.
    Include/Exclude/ Between sites

    Include option includes the particular the IP address, address range, or network.

    Exclude option excludes the particular the IP address, address range, or network.

    Between sites option allows you to group the traffic between sites, which can be defined by two networks or IP addresses.

    Filter based on DSCP names Allows you to set filters based on the DSCP names of the applications.
    Associated Interfaces If you need to filter this IP group further, based on devices or different interface combinations, click the "Select Devices" link and select the different devices and interfaces whose traffic needs to be included in this IP group.
    IP Group Speed Enter the interface speed (in bits per second) for calculating percentage of traffic for this IP group.
    Note If you add a new combination of ports and protocol, a popup opens stating that this combination of ports and protocol has not been mapped to any application. Add the combination as a new application in the same popup, and click Update to update the Application Mapping list with the new application.

    Managing IP Groups

    Click the IP Group Management link in the Admin Operations box to view the list of IP groups created so far. The current status of the IP Group is also shown as Enabled or Disabled. Select the IP group that you want to modify, and click the Modify button to edit its settings. Once you are done, click Addto save and activate the new changes. To change a IP group's status from Enabled to Disabled or vice-versa click on the current status of the IP Group. It is possible to Enable or Disable all the IP Groups at once by using the "Enable All" and "Disable All" buttons.

    To delete an IP group, select the IP group and click the Delete button. Deleting an IP group removes the IP group from the list of IP groups managed. All users assigned to this IP group will not see this IP group listed on their Dashboard.

    Note
    Unmanaging an IP group will lead to bill generation for the particular IP group, IF that IP group has been selected for billing.

    Bulk loading IP Groups

    NetFlow Analyzer allows bulk loading of IP group using the XML file(ipGroup.xml) contained in the location: OpManager\troubleshooting. using this file it is possible to define multiple IP groups at once. A sample configuration code looks like:

    <CONF_IPGroup> <IPGroups ip_group_name="Engineering" ip_group_desc="description in detail" ip_group_speed="1000000"> <GrpIPAddress addr_id="12.12.12.12" flag="include"/> <GrpIPNetwork netmask_addr_id="255.255.255.0" network_addr_id="12.12.13.0" flag="include"/> <GrpIPRange netmask_addr_id="255.255.255.0" start_addr_id="12.12.14.1" end_addr_id="12.12.14.100" flag="exclude"/> <ApplicationNames port="80" protocol="TCP"/> <Selected_Devices> <Router Router_Name="192.168.111.113"> <Interface interface_name="IfIndex1" /> <Interface interface_name="IfIndex3" /> </Router> </Selected_Devices> </IPGroups> </CONF_IPGroup>

    Within this configuration it is possible to have any number of GrpIPAddress or GrpIPNetwork or GrpIPRange or ApplicationNames with Inteface selection.

    It is also possible to add specific criteria/exceptions to the group definition such as:

    • configuring an IP group with just one network
    • configuring an IP group with just one address
    • configuring an IP group with just one range
    • configuring an IP group with just port and protocol

    The user has to ensure that an IP group with the same name does not already exist and that the IP group name does not exceed 50 characters.

    If all the IP groups are loaded successfully, you can see the message "All ipgroups are succesffully loaded" in the User Interface. If you try to load the same IP groups twice, you can see the message "Error in loading. IPGroup with name ':grp1' Already exists." in the User Interface. If there is no such file in the directory, you can see the message "OpManager_HomeTroubleshootingipGroup.xml is not found." in the User Interface.

    After adding the IP group(s) it is possible to selectively include/exclude a IP Network/ IP Address/ IP Range from the user interface of the product.

    Enabling WAN using IP Group Management

    IP Group Management lets you monitor departmental, intranet or application specific traffic exclusively. You can create IP groups based on IP addresses and/or a combination of port and protocol.Now, using IP Group Management you can also monitor wan round trip time for specific IP address or IP range and analyze the latency and quality of service between two locations.

    In order to enable WAN RTT monitoring using IP Group Management you need to specify the individual IP address or IP range. You can also monitor range latency between two different sites under IP group option.The IP address under the specified IP group acts as the destination IP address while you have to specify the source IP address. Using the include and between sites option you can monitor WAN performance for individual and range of IP addresses but for for IP networks.The added monitor can be viewed under the traffic tab of IP groups along with the average WAN round trip time details. Click on the check box that reads "Also Enable WAN RTT" to enable WAN RTT monitoring under IP Group Management.

    Generate consolidated reports based on utilization for IP groups.

    Application Group

    Application Groups allow you to define your own class of applications by including one or more applications. For example, you might want to classify all your database applications like Oracle, MySql, MS-Sql in to one group called the DataBase group. Initially when no application groups have been created a message to that effect is displayed. The Application Group report can be viewed on the Application tab for each interface.

    DSCP Group

    Quality of Service is used to measure, improve and guarantee transmission rates, error rates and other characteristics in a networkes setting. The DiffServ model for DSCP Mapping was developed to differentiate IP traffic so that the traffic's relative priority could be determined on a per-hop basis. Using DSCP Mapping you can name the DiffServ code points and monitor their traffic in troubleshooting reports under the DSCP tab. Note that the DSCP reports can be viewed on the Troubleshooting page by clicking on the DSCP tab.The DCSP group is very valuable in the deployment of QoS.
