You can view and manage IPv4 address data in the IP Map and IP List panels. Grid Manager displays the IP Map and List panels for a specific network after you navigate through the network hierarchy, or when the selected network does not have subnets under it.

    IP  Map

The IPv4 Map panel provides a graphical representation of all IPv4 addresses in a given subnet. IP Map displays cells that represent IPv4 addresses. Each cell in the map represents an IPv4 address, and its color indicates its status as described in the legend section. You can run a network discovery on the selected network, and the status of each IP address is updated accordingly. For information, see About Discovery.
Each IP Map panel can accommodate up to 256 cells with each cell representing an IP address. If a given network has more than 256 addresses, additional IP addresses are displayed by paging to the next page. You can use the page navigation buttons to page through the IP addresses. To go to a specific IP address, you can enter the IP address in the Go to field or click a specific cell in IP Map. IP Map has a basic and an advanced view. You can toggle between these views by clicking Toggle Basic View or Toggle Advanced View. As illustrated in Figure 13.7, the status of an IP address is represented with a different color in the IP Map panel.
In the basic view, the IP Map panel displays the following IP address status:

  • Unused: An IP address that has not been detected and is not associated with any network device or active host on the network.
  • Conflict: An IP address that has either a MAC address conflict or a DHCP lease conflict detected through a network discovery.
  • Used: An IP address that is associated with an active host on the network. It can be a resource record, fixed address, reservation, DHCP lease, or host record.
  • Pending: An IP address that is associated with a scheduled task or approval workflow, and the associated operation has not been executed yet. This IP address is not considered when using the next available IP address function.
  • Selected IP Address: The IP address that you selected.
  • DHCP Range: The IP addresses within a DHCP range in the network. The appliance highlights the cells using a blue background.
  • Reserved Range: A range of IP addresses that are reserved for statically configured hosts. They are not served as dynamic addresses. You can allocate the next available IP from the reserved range when you create a static host.

 Figure 13.7 IP Map - Advanced View 

In the advanced view, the IP Map panel displays additional status as follows:

  • Unmanaged: An IP address that has a discovered host, is not previously known to the appliance, and does not have an A record, PTR record, fixed address, host address, lease, or is not within a DHCP range. You can change an unmanaged address to a host, DHCP fixed address, A record, or PTR record. You can also clear an unmanaged address. All existing administrator permissions apply to the unmanaged addresses.
  • Fixed Address/Reservation: A host that is either a fixed address or reservation.
  • DNS Object: An object that is configured for DNS usage.
  • Host Not in DNS/DHCP: An IP address that is associated with a host record, but is not configured for DHCP or DNS services.
  • Active Lease: An IP Address that has an active DHCP lease.
  • DHCP Exclusion Range: A range of IP addresses within a DHCP range. The appliance cannot assign addresses in the exclusion range to a client. You can use these addresses as static IP addresses. This prevents address conflicts between statically configured devices and dynamically configured devices.
    Note: For a Microsoft split-scope range, the appliance highlights the cells using a combination of orange and pink background colors when the network is managed by two Microsoft servers. For a DHCP exclusion range, the appliance highlights the cells using an orange background.

Under the IP map, Grid Manager displays the following information for the IP address that you have selected in the map:

  • Type: The object type that is associated with the IP address. For example, this can be Lease, IPv4 DHCP Range or Fixed Address.
  • Comment: Additional information about the IP address.
  • Lease State: The lease state of the IP address. This can be one of the following: Free, Backup, Active, Expired, Released, Abandoned, Reset, BootP, Static, Offered, or Declined.
  • Name: The name of the object type associated with the IP address. This field displays the name of the object type in the native character set if a host record contains IDNs. If a host record contains IDNs in punycode, this field displays the name in the punycode representation. For example, if the IP address belongs to a host record, this field displays the hostname. For IDNs, this field displays the name in the native character set. If punycode is used, then the appliance displays name in punycode.
  • MAC Address: The discovered MAC address of the host. This is the unique identifier of a network device. The discovery acquires the MAC address for hosts that are located on the same network as the Grid member that is running the discovery. This can also be the MAC address of a virtual entity on a specified vSphere server. The appliance displays an X mark beside the MAC address if it is invalid. For more information about invalid MAC addresses, see Synchronizing IP Addresses withInvalid MAC Addresses.
  • DHCP Fingerprint: The name of the DHCP fingerprint or vendor ID of the network device that was identified through DHCP fingerprint detection. This field displays No Match for devices that do not have any DHCP fingerprint information. For information about DHCP fingerprints, see DHCP Fingerprint Detection.

You can do the following in the IP Map panel:

  • Click Go to DHCP View to view DHCP properties of a selected network.
  • Select an address range by clicking once on a start address and then use SHIFT+click on the end address. Click Add -> Range from the Toolbar to add the selected range as an IPv4 or IPv6 DHCP range or reserved range.

    IP Address List

The IP address List panel displays all IPv4 addresses of a selected subnet in table format. The list provides information about the IP addresses in a hierarchy view. You can use this list to view detailed information about each IP address and its related objects in a selected network. This list provides information such as address status, object type, and usage.
You can configure filter criteria to display only IP addresses that you want to see in the table. For example, you can enter "MAC Address begins with 00" as the filter criteria to view only IP addresses that have associated MAC addresses that begin with 00. You can also enter a specific IP address in the Go to field to view information about the address.
Grid Manager can display the following information for the IP addresses. You can edit the columns to display information that is not shown by default.

  • IP Address: The IP address of the corresponding record. The appliance highlights disabled DHCP objects in gray. A DHCP object can be an DHCP address range, fixed address, reservation, host configured for DHCP, or roaming host with an allocated IP address.
  • Name: The name of the object type associated with the IP address. For example, if the IP address belongs to a host record, this field displays the hostname.
  • MAC Address: The discovered MAC address of the host. This is the unique identifier of a network device. The discovery acquires the MAC address for hosts that are located on the same network as the Grid member that is running the discovery. This can also be the MAC address of a virtual entity on a specified vSphere server.

  • Bridge Domain: The name of the discovered bridge domain. This column will display values only for IP addresses that are discovered from Cisco APIC through Network Insight or NetMRI. If discovered by NetMRI, the value will be populated through IPAM Sync. Otherwise, this column will be blank. For information about how to configure Cisco APIC, see Configuring Cisco Application Policy Infrastructure Controller (APIC).

  • Tenant: The name of the discovered tenant. This column will display values only for IP addresses that are discovered from Cisco APIC through Network Insight or NetMRI.

  • EPG: The name of the end point group. This column will display values only for IP addresses that are discovered from Cisco APIC through Network Insight or NetMRI. If discovered by NetMRI, the value will be populated through IPAM Sync. Otherwise, this column will be blank. For information about how to configure Cisco APIC, see Configuring Cisco Application Policy Infrastructure Controller (APIC).

  • DHCP Client Identifier: For an IPv4 address, the DHCP Unique Identifier of the host.
  • Port Reservation: Lists any Port Reservation from Network Insight that is associated with the IP address. The information takes the form of device name:interface name.
  • VIP: Indicates when the IP address is operating as a Virtual IP and operates in router redundancy.
  • Status: The current status of the corresponding record. This can be Used or Unused.
  • Type: The object type that is associated with the IP address. For example, this can be Broadcast, Lease, IPv4 DHCP Range or Fixed Address.
  • Discover Now: Indicates when the network is undergoing a current discovery process. A "Pending" icon appears in this column when you start the discovery and displays Completed after the completion of the discovery process.
  • Usage: Indicates whether the IP address is configured for DNS or DHCP.
  • Lease State: The lease state of the IP address. This can be one of the following: Free, Backup, Active, Expired, Released, Abandoned, Reset, BootP, Static, Offered, or Declined.
  • User Name: The name of the user who received the lease for the IP address.
  • Task Name: The name of the task that collected the discovered data. It is usually the ID or task name that collected the data. It is defined on the corresponding Trinzic Network Automation appliance when you import the discovered data to the NIOS appliance. The task name should be defined in the vDiscovery task manager for vDiscovery.
  • Comment: Additional information about the IP address.
  • First Discovered: The timestamp when the IP address was initially discovered. This data is read-only.
  • Last Discovered: The timestamp when the IP address was last discovered. This data is read-only.

This field displays No Match for devices that do not have any DHCP fingerprint information. For information about DHCP fingerprints, see DHCP Fingerprint Detection.
  • Site: The site to which the IP address belongs. This is a predefined extensible attribute.
  • Disabled (hidden): Indicates whether the DHCP or DNS record is disabled.

Note: For an IP address that falls within a DHCP range, Grid Manager displays extensible attribute values for the DHCP range and fixed address or host record. When you view the same IP address in the DHCP tab however, Grid Manager displays only the extensible attribute values associated with the fixed address or host record, but not the DHCP range. For example, when you define extensible attribute State with the value California for DHCP range 1.0.0.1 – 1.0.0.5, and then define extensible attribute State with the value of Alaska for fixed address 1.0.0.3, Grid Manager displays both California and Alaska in the State field for IP address 1.0.0.3 in the IP Address List view. However, when you view 1.0.0.3 from the DHCP tab, the State field displays Alaska only.

  IP List Neighbor Information

Other values will be available for display in the List page. Most of the hidden columns consist of information discovered by Grid Manager, to identify devices connected to the network interfaces neighboring the listed IP addresses in the table. These data columns are hidden and must be selected for display by the operator by selecting the Visible check box for each field when editing the columns for the table. (Most of this information will not appear unless a device is recognized in IPAM or is in managed state under IPAM.) Additional values include:

  • Discovered Name: The discovered name of the device bound to the IP address. The IP address may be just one of several or many IP addresses bound to the device on a specific interface.
  • Discovered MAC Address: The discovered MAC of the interface bound to the IP address.

Note: If you change the IP address of an existing record to a new one in the IP MAP tab when the Grid Audit Logging is set to Brief, then NIOS will not display modification or transition details about the new IP address in this tab. You can only view subsequent modifications and deletions to the new IP address. However, you can view the audit log history and transition details of the old IP address, but you cannot view the initial transition from an old IP address to the new IP address.

  Managing IPv4 Addresses

You can do the following from the IP Map and List panels:

Adding IP Addresses to Existing Host Reco rds

You can add unused and unmanaged addresses, including all their information, to existing host records. When you add an unmanaged address to a host record, the appliance adds the discovered data to the host record. You can select the desired host to which you want to add the unmanaged address.
To add an unmanaged IP address to an existing host record:

  1. From the IP Map or List panel, select an IP address, and then click Add -> Add to Existing Host from the Toolbar.
  2. In the Select Host dialog box, do the following:
    • In the table, select the host to which you want to add the selected IP address. You can also use the filters or the Go To field to narrow down the host list. For information, see Using Filters and Using the Go To Function.
    • Click the Select icon.
      Grid Manager displays the Host Record editor.
  3. In the Host Record editor, update the host properties as described in Choose one of the following from the Save & ... drop-down button menu.
  4. Save the configuration and click Restart if it appears at the top of the screen. To close the editor without saving the changes, click the Close icon.

Clearing Unmanaged Data

You can clear the status of unmanaged data at the network and IP address levels. When you clear an unmanaged address, the status of the IP address changes to Unused. An unmanaged address is an IP address with a discovered host, is not previously known to the appliance, and does not have an A record, PTR record, fixed address, host address, lease, or is not within a DHCP range. You can change an unmanaged address to a host, a DHCP fixed address, an A record, or a PTR record. You can also clear the unmanaged data associated with the address.
To clear unmanaged data:

  1. From the IP Map or List panel, select the IP address for which you want to clear unmanaged data, and then click Clear -> Clear Unmanaged Data from the Toolbar. You can select multiple IP addresses.
  2. In the Clear Unmanaged data dialog box, click Yes.
