This section explains how to connect a Qumulo cluster to multiple virtual networks by using VLAN tagging.

Each node in a Qumulo cluster has a single NIC labeled bond0 and creates a bond between two physical ports by using either active backup (a redundant configuration in which one port is active while the other is in standby mode) or LACP (the aggregation of multiple, parallel network connections).

When you create a Qumulo cluster, its configuration includes a network named Default. The configuration uses DHCP, the bond, and a single default gateway associated with the bond.

Step 1: Configure Default DHCP Settings

You can configure your Qumulo cluster from the default DHCP configuration. If you have already configured a single static network, skip this step and add another network.

  1. To assign a default gateway, run the qq network_mod_interface command. For example:

    qq network_mod_interface \
  2. To configure the Default network to use static (rather than DHCP) addressing, run the qq network_mod_network command. For example:

    qq network_mod_network \
      --network-id 1\ 
      --assigned-by STATIC \
      --ip-ranges \
      --floating-ip-ranges \
      --netmask \
      --dns-servers \
  3. Log in to the system by using one of the assigned IP addresses.

Step 2: Add More Networks

After you configure the first network for your Qumulo cluster, you can add more networks to it.

  1. To add a network, run the qq network_add_network command. For example:

    qq network_add_network \
      --name MyNetworkName \
      --ip-ranges \
      --floating-ip-ranges \
      --netmask \
      --dns-servers \
      --dns-search-domains \
      --mtu 1500 \
      --vlan-id 200
  2. To view the details your networks, run the qq network_list_networks command.

  3. To view the IP addresses assigned to the nodes in your cluster, run the qq network_poll command.
