NICs

This topic applies to Logger Appliances only.

The NICs tab enables you to set the IP addresses for the network interface cards (NICs) on your system. Additionally, you can configure the hostname and default gateway for your system.

To set or change the NICs settings:

  1. Click System Admin from the top-level menu bar.
  2. Click Network in the System section.

  3. In the NICs tab, enter the following settings. To edit the IP address, subnet mask, or speed/duplex of an NIC, select the NIC and click Edit above the NIC Name list.

    Setting

    Description

    Default Gateway

    The IP address of the default gateway.

    Hostname

    The network host name for this system. Make sure that your DNS can resolve the host name you specify to your system’s IP address. Performance is significantly affected if DNS cannot resolve the host name.

    This name must be identical to the domain specified in the Certificate Signing Request, described in Generating a Certificate Signing Request (CSR).

    Note: If you previously used a self-signed or CA-signed certificate on this system and are now changing its host name, you must regenerate a new self-signed certificate or CSR. A new certificate ensures that the connectors in FIPS mode which communicate with your system are able to validate the host name. For more information about generating a CSR, see Generating a Certificate Signing Request (CSR).

    Automatically route outbound packets (interface homing)

    When this option is enabled (checked box), the response packets are sent back on the same system interface on which the request packets had arrived. Enabling this option can improve performance as the routing decisions do not need to be made (using the default gateway information and static routes) to send packets out from your system. If you have static routes configured, they are ignored when this feature is enabled.

    When this feature is disabled (unchecked box), the static routes (if configured) are used to determine the interface through which the response packets should leave your system.

    If you configure only one network interface, this setting does not provide any additional benefit.

    IP Address

    The IP address for each network interface card (NICs) in your system. These IP addresses should be on separate subnets to avoid confusion and to allow load balancing between receivers and forwarders.

    Add NIC Alias

    You can create an alias for any listed NIC. To do so:

    1. Highlight the NIC for which you want to create an alias.
    2. Click Add.
    3. Create an alternative IP address for the alias.
    4. Click Save.

    You can identify the alias from its original by an appended colon alongside a digit indicating the number of aliases you have created on a particular NIC.

    Note: You cannot alter the speed of an IP alias.

    You can create as many aliases as you choose.

    Subnet Mask

    The subnet mask associated with the IP address you entered for an NIC.

    Speed/Duplex

    Choose a speed and duplex mode, or let your system determine the network speed automatically:

    • Auto (recommended)
    • 10 Mbps - Half Duplex
    • 10 Mbps - Full Duplex
    • 100 Mbps - Half Duplex
    • 100 Mbps - Full Duplex
    • 1 Gbps - Full Duplex
  4. Click Save.
  5. Click Restart Network Service to put the changes into effect.
