  1. From the Grid tab, select the Grid Manager tab -> Members tab -> Grid_member check box, and then click the Edit icon.
  2. In the Network -> Basic tab of the Grid Member Properties editor, click the Add icon of the Additional Ports and Addresses table and select LAN2(IPv4) or LAN2(IPv6) from the drop-down list. Enter the following:
    • Interface: Displays the name of the interface. You cannot modify this.
    • Address: Type the IP address for the LAN2 port, which must be in a different subnet from that of the LAN1 and HA ports.
    • Subnet Mask (IPv4) or Prefix Length (IPv6): Specify an appropriate subnet mask for IPv4 address and prefix length for IPv6 address.
    • Gateway: Type the default gateway for the LAN2 port.
    • VLAN Tag: Enter the VLAN tag ID if the port is configured for VLANs. You can enter a number from 1 to 4095.For more information about VLAN, see About Virtual LANs.
    • Port Settings: From the drop-down list, choose the connection speed that you want the port to use. You can also choose the duplex setting. Choose Full for concurrent bidirectional data transmission or Half for data transmission in one direction at a time. Select Automatic to instruct the NIOS appliance to negotiate the optimum port connection type (full or half duplex) and speed with the connecting switch automatically. This is the default setting. You cannot configure port settings for vNIOS appliances.
    • DSCP Value: Displays the Grid DSCP value. To modify, click Override and then enter the DSCP value. You can enter a value from 0 to 63. For more information about DSCP, see Implementing Quality of Service Using DSCP.
    • LAN2 Virtual Router ID (if HA): If the appliance is in an HA pair, enter a VRID number.
  3. Save the configuration and click Restart if it appears at the top of the screen.

  1. From the Data Management tab, select the DNS tab -> Members tab -> Grid_member check box, and then click the Edit icon.
  2. In the General -> Basic tab of the Member DNS Configuration editor, do the following:
    If you are running DNS for IPv4: In the General -> Basic tab of the Member DHCP Configuration editor, select the IPv4 check box for LAN2 under DNS Interfaces. If you have configured Infoblox Subscriber Services, you can tag the interface with an IP space discriminator in order to support multiple subscribers using the same IP address. Select an IP space discriminator from the IP Space Discriminator drop-down list for the LAN2 interface. Note that the IP Space Discriminator field is displayed only for Grid members that have the RPZ license installed. Otherwise, this field is hidden. For more information about IP space discriminators, see Adding IP Space Discriminators.
    If you are running DNS for IPv6: In the General -> Basic tab of the Member DHCP Configuration editor, select the IPv6 check box for LAN2 under DNS Interfaces. (An IPv6 address must also be provisioned for the port.) If you have configured Infoblox Subscriber Services, you can tag the interface with an IP space discriminator in order to support multiple subscribers using the same IP address. Select an IP space discriminator from the IP Space Discriminator drop-down list for LAN2 interface. Note that the IP Space Discriminator field is displayed only for Grid members that have the RPZ license installed. Otherwise, this field is hidden. For more information about IP space discriminators, see Adding IP Space Discriminators.
    You can run either or both protocols for DNS depending on your network deployment. 
    • Automatically create glue A and PTR records for LAN2's address: The NIOS appliance can automatically generate A (address) and PTR records for a primary name server whose host name belongs to the name space of the zone. Select this check box to enable the appliance to automatically generate an A and PTR record. 
    • Automatically create IPv6 glue AAAA and PTR records for LAN2's address: automatically generate AAAA and PTR records for the LAN2 IPv6 address. A glue record is the IP address of a name server held at the domain name registry. They are needed to set a domain's name server to a host name within the domain. Example: to set the name servers of ns1.corpxyz.com and ns2.corpxyz.com, provide the glue records, which are in effect the IP addresses, for ns1.corpxyz.com and ns2.corpxyz.com, within specific DNS record types.
      Without the glue records, DNS requests never resolve to the correct IP address because the domain registry does not associate the IP with the correct records.
  3. In the General -> Advanced tab (click Toggle Advanced Mode if necessary), select one of the following from the Send queries from and the Send notify messages messages and zone transfer request from drop-down lists:
    • VIP: The appliance uses the IP address of the HA port as the source for queries, notifies, and zone transfer requests.
    • MGMT: The appliance uses the IP address of the MGMT port as the source for queries, notifies, and zone transfer requests.
    • LAN2: The appliance uses the IP address of the LAN2 port as the source for queries, notifies, and zone transfer requests.
    • Any: The appliance chooses which port to use as the source for queries, notifies, and zone transfer requests.
      The Sendqueriesfrom drop-down list also includes loopback IP addresses that you configured. You can select a loopback address as the source for queries.
  4. Save the configuration and click Restart if it appears at the top of the screen.
  5. Click Restart to restart services.
