    Configuring DHCP Server Options in Basic Mode

    This procedure describes how to configure DHCP server options using Basic mode in the Selfcare Portal.

    Note: For a VPN site, you can configure either DHCP server or DHCP relay, but not both. You can configure DHCP server in one site and DHCP relay at other sites can point to the target DHCP server. Alternatively, you can configure the MX Series router DHCP relay option to point to a DHCP server located at your site.

    Caution: DHCP server is supported only for sites where all access links are connected to the same routing instance and the routing instances that are connected to the access links are for only one site. cCPE Selfcare Application does not enforce this restriction. If your access links and routing instances are not connected in this way, the DHCP server does not operate correctly.

    To configure the basic settings for the DHCP server:

    1. In the Selfcare Portal task pane, select Administration > Site Configuration.

      The Site Configuration page is displayed.

    2. From the Site selection list, select the site for which you want to configure the DHCP server.
    3. Select the DHCP Server tab.

      The DHCP Server dialog box is displayed.

    4. Select the Basic button.
    5. (Optional) Add an address pool:
      1. Select the Add (+) icon next to the Pools list.

        The Add Pool dialog box is displayed.

      2. In the New Pool Name field, specify a name for the new address pool and select Add.

        The Pools Settings dialog box is displayed, an example of which is shown in Figure 1.

      3. Specify the information for the fields in the Pool Settings dialog box described in Table 1.

      Table 1: DHCP Server Pool Fields for Basic Mode

      Field

      Action

      Pool Name

      Specify the name of the address pool. The pool name is an arbitrary label used to distinguish different address pools.

      Network

      Specify a network range in the form: x.x.x.x/mask; the IP address must be routable.

      Default Router

      Specify a default router.

      Note: To configure multiple default routers, use the DHCP server Advanced mode.

      Domain Name

      Specify the name of the domain in which clients search for a DHCP server host. This is the default domain name that is appended to hostnames that are not fully qualified. This is equivalent to DHCP option 15.

      Primary DNS Server

      Specify the primary Domain Name System (DNS) name server by IP address. The name server resolves hostname-to-client mappings.

      This is equivalent to DHCP Option 6.

      Note: To configure more than the primary and secondary name servers, use the DHCP server Advanced mode.

      Secondary DNS Server

      Specify the secondary Domain Name System (DNS) name server by IP address. The name server resolves hostname-to-client mappings.

      This is equivalent to DHCP Option 6.

      Note: To configure more than the primary and secondary name servers, use the DHCP server Advanced mode.

      Pool Range (low)

      Specify the lower limit of the address range.

      Pool Range (high)

      Specify the upper limit of the address range

    6. (Optional) Modify an existing address pool:
      1. From the Pools list on the DHCP Server page, select the name of the address pool you want to modify.
      2. Select the Pools Settings tab.

        The Pools Settings dialog box is displayed, an example of which is shown in Figure 1.

    7. Specify the information for the fields in the Pool Settings dialog box described in Table 1.
    8. Select Update to save the changes.
