You use the IPv4 Network or IPv6 Network editors to exclude IP addresses or ranges of IP addresses from discovery within the specified network. For more information, see Disabling Discovery for a Network.
Host records, fixed address and IPv4 reservations can be excluded from discovery. You may also exclude an IP address or a range of IPs within a network from discovery.
You may create a network and choose not to discover it at that time, by disabling both Enable Immediate Discovery and Enable Discovery. If you disable the Enable Discovery check box, the network will never be discovered unless you change the setting again at a later time.
Conversely, you can explicitly exclude specific IPs or IP ranges from discovery. Discovery will never take place on these IPs unless the admin specifically changes their exclusion setting.
Administrators can specify IPv4 and/or IPv6 addresses that must be immediately discovered by the appliance. Some devices may need exclusion because they do not support SNMP, or for other organizational reasons.
Devices matching IP addresses selected for immediate discovery (using the Discover Now feature described in Using Discover Now to Discover an Existing Object) are given one-time priority over other discovered devices, for data collection and counting toward any device found matching the license limits.
A device specified through an IP address can also be excluded from discovery or management.
You can use the IPAM IP Map or IP List page to quickly exclude IP addresses and selected ranges of IP addresses from discovery. For example, you may have Infoblox appliances or routers that provide the gateway to networks that are already managed by Grid Manager, or devices on which you do not wish to have discovery operations take place.
Click on any network or network container in the list. The IP Map appears for the selected network.
You may also use the List page for the selected network to exclude IPs or selected ranges of IPs. However, you have to page through or search through the pages comprising the list view to locate the IPs you want to exclude. (If you know the IP address value in the List view but it does not appear on the page, enter it in the Go to field to search for the IP.) The IP Map view allows you to view every IP address in a selected network, such as a /24 prefix.
You can click the Action iconfor any List record and choose Exclusion–>EnableExclusion.
To locate an IP to exclude within a network container:
A parent network container may exclude IPs, and you may add and remove discovery exclusions within network containers. You can drill down to the child networks in the Net Map view to perform exclusions on IPs. For example, consider a /16 network container that has a number of smaller /24 child networks within it. Right-clicking on any child network in the network container and choosing Edit from the popup menu, opens the editor with its Discovery Exclusions tab, where you can perform exclusions within the child network.
You can create a new object from the main Data Management –> IPAM or Data Management –> DHCP pages.
For DHCP, the home Networks page appears, showing all networks reachable by DHCP.
The network lists between IPAM and DHCP will likely differ, because networks can be set to be Disabled from DHCP. IPAM provides a complete list of all networks configured or discovered by Grid Manager.
2. Select a network from the IPAM home page: by checking the network's check box, searching for the network in the GoTo box, or using the Next Page, Previous Page and Last Page selectors.
a. Select a network from the DHCP–>Networks home page by clicking its check box.
3. Expand the Toolbar and click the Add button, and select the object type from the menu, such as Host, FixedAddress–>IPv4, or other object type.
4. In the second Wizard step, click NextAvailableIP to obtain the next available IP address in the chosen network. For more information about obtaining the next available IP address, see About the Next Available Network or IP Address.
For adding a host record, the first step in the Add Host Wizard requires adding an IP address.
5. If the network of the IP address is served by a Grid member, Grid Manager displays the AssignIPAddressby section, with its MACAddress, DHCPClientIdentifier and DHCPRelayAgent settings. Select the different options as needed to define a fixed IP Address or other object.
6. Click Next to continue to the DHCP Options page in the wizard.
7. If you do not wish to configure DHCP Options for this Fixed IP, click Next to go to the following Wizard step.
8. (Optional) In the DeviceInformation page, select the Device Type and the Device Vendor, or, if you do not wish to configure device settings for the current object, click Next to go to the next Wizard step, for defining discovery settings.
For more information about Device Information settings, see Creating Port Reservations for IPAM Objects.
9. Choose from the options on the Step 5 Wizard page:
You can apply a set of CLI Credentials to the specific fixed address object. To override the inherited CLI credentials from the Grid, select the Override CLI Credentials check box. You can enter the admin user Name and Password values and, if necessary, an Enable Password. The values you enter here are specific only to the current object.
Clicking Schedule for Later is a navigational button to allow you to skip quickly to the scheduling step in the Wizard. You can return at any time to complete remaining Wizard steps to finish creating the object. You may click the Schedule for Later button at any time in the Wizard process. For more information, see Scheduling New IPAM/DHCP Objects and Associated Port Configurations.
You may exclude IP addresses from discovery from within a number of different contexts in Grid Manager. Under IPAM, you can exclude in the IP Map and IP List pages. The IP List page provides an Exclude data column that directly shows the exclusion status for all IPs in the selected network. Various objects, such as host records, IPv4 and IPv6 fixed addresses, and IPv4 reservations, may be excluded from discovery.
You may view excluded IP addresses in the IP List page or in the network editor's Exclusions tab.
