Add a DHCP server to manage its scopes and IP address leases. A scope is a range of IP addresses that the DHCP server leases to clients on a subnet.

In this topic:

Add a DHCP server

 

Before adding a DHCP server to IPAM, it must already exist as a node. Therefore, verify that you have completed the following tasks:

The DHCP Server is added to the DHCP & DNS Management page, and begins scanning IP address and scope lease activity.

  1. Click Settings > All Settings > IPAM Settings > Add DHCP server.

  2. Select the server from the Choose DHCP Server drop-down menu.

  3. Select a credential type, and select the credential name, or else create a new credential.

    To create a new credential, you will need a valid user name and password for Windows or ISC credentials, plus an Enable password for the Enable Level for CISCO or ASA. For information on creating a new credential, see Credentials.

    The account specified in the credential must exist on the DHCP server and be a member of one of the three following groups:

    • DHCP Users

    • DHCP Administrators

    • Local Administrators

    IPAM impersonates the specified account on the local computer in order to gain access.

    If the IPAM computer is not within the same domain as the DHCP server, the IPAM computer must have the identical account and password.

  4. Click Test to verify the credential on the selected server.

  5. Select your default DHCP Server Scan Settings, and click Add DHCP Server.
  6. Select the scan interval. Default is set to four hours.
  7. If you want to automatically add new scopes and subnets after scanning, check the box.
  8. If you want to IPAM to scan using ICMP and SNMP to obtain additional IP Address details, check the Enable subnet scanning box and select the scanning interval.
  9. If you want to use or create an hierarchy group to which subnets discovered by this server are assigned, select it from the Hierarchy group name drop-down. If you leave this as IP Networks, all discovered subnets will go to the IP Networks hierarchy group.

    Hierarchy groups enables you to have overlapping IP addresses, which can happen if you have identical subnets in different locations monitored by different DHCP servers on the same network.

Edit DHCP server properties

  1. Go to My Dashboards > IP Addresses > DHCP & DNS Management.
  2. Click DHCP if not already selected.
  3. Select the DHCP server to edit.
  4. Click Edit.
  5. Edit the server properties.

    The properties available are specific to IPAM and not related to any settings on the DHCP server.

  6. Click Save.

Remove a DHCP server

Remove a DHCP server from the IPAM Web Console.

  1. Go to My Dashboards > IP Addresses > DHCP & DNS Management.
  2. Click DHCP if not already selected.
  3. Select the DHCP server to be removed.
  4. Click Remove.

    A pop-up window is displayed, asking if you also want to removes scopes and corresponding subnets.

  5. Click Delete Listed Items.
