Configure network teaming

You access the Network Teaming Management screen from the Network Configuration screen. Use the Network Teaming Management screen to create, delete, and edit network teaming configurations.

Note   Each NIC can belong to only one network teaming configuration.
  1. Connect to the console. See Connect to the console for more information. The Appliance Console menu is displayed.
  2. Type N, Network Settings.
  3. If necessary, type T on the Network Configuration screen to display the Network Teaming Management screen.
  4. Do one of the following:
    • Create a new network teaming configuration. Type C. A list of NICs available for network teaming displays. See Configure network teaming.
    • Remove an existing network teaming configuration. Type R. A list of existing network teaming configurations displays. Type the number that corresponds to the network teaming configuration you want to remove. See Configure network teaming.
    • Edit an existing network teaming configuration. Type E. A list of existing network teaming configurations displays. Type the number that corresponds to the network teaming configuration you want to edit. The same options that were available when you created the configuration displays. See Configure network teaming.

Create a network teaming configuration

Network teaming, or link aggregation, is a way to use multiple NICs to increase throughput or to provide redundancy in case one of the NICs fails.

  1. Type C on the Network Teaming Management screen to display the Create Network Teaming Members Configuration screen.
  2. Type the number of one or more NICs you want to configure as a network teaming configuration. NICs unavailable for network teaming configuration are grayed out.
  3. After you select NICs for configuration, type D, Done, to proceed to the Create New Network Teaming Configuration screen to finish creating the configuration. Alternatively, you can type B, Back, to go back to the Network Teaming Management screen without creating the configuration.
  4. On the Create New Network Teaming Configuration screen, select a protocol. If you select Static, specify an IP address and netmask for the configuration.
  5. Type e to display the Team Driver Options screen. Do the following:
    1. Select a Team Mode. See Configure network teaming.
    2. Specify a value in milliseconds for MII monitoring. The value you specify is how often the link state of each NIC is inspected for link failures.
    3. Type D, Done, to go back to the Create New Network Teaming Configuration screen with the opportunity to save your changes or type B, Back, to discard your changes and go back to the Create New Network Teaming Configuration screen.
  6. On the Create New Network Teaming Configuration screen, type S, Save, to save your changes and create the configuration, or type C to cancel without saving.

Edit a network teaming configuration

  1. Type E on the Network Teaming Management screen to display the Edit Network Teaming Configuration screen.
  2. Type the number of the network teaming configuration you want to edit. The Edit Network Teaming Configuration screen displays the options you can edit. Do any of the following:
    • Type M to display a screen where you can add or remove team members. After you have added or removed members, type S to save your changes or C to Cancel them.
    • Select a protocol. If you select Static, specify an IP address and netmask.
    • Type E to specify teaming driver options. See Configure network teaming.
  3. Type S to save your changes or C to Cancel them.

Remove a network teaming configuration

  1. Type R on the Network Teaming Management screen to display the Remove Network Teaming Members Configuration screen.
  2. Type the number of the network teaming configuration you want to remove.
  3. Type Y to confirm your selection, remove the configuration, and return to the Network Teaming Management screen; or N to return to the Network Teaming Management screen without removing any configuration.

Network team driver options

The following is a list of the available network team driver options.

Option Description
Round-robin (balance-rr) Transmit network packets in sequential order from the first available network interface (NIC) slave through the last. This mode provides load balancing and fault tolerance.
Active-backup (active-backup) Only one NIC slave in the bond is active. A different slave becomes active if, and only if, the active slave fails. The single logical bonded interface's MAC address is externally visible on only one nic (port) to avoid distortion in the network switch. This mode provides fault tolerance.
XOR (balance-xor) Transmit network packets based on [(source MAC address XOR'd with destination MAC address) modulo nic slave count]. This selects the same nic slave for each destination MAC address. This mode provides load balancing and fault tolerance.
Broadcast (broadcast) Transmit network packets on all slave network interfaces. This mode provides fault tolerance
IEEE 802.3ad Dynamic link aggregation (802.3ad) Creates aggregation groups that share the same speed and duplex settings. Utilizes all slave network interfaces in the active aggregator group according to the 802.3ad specification.
Adaptive transmit load balancing (balance-tlb) Linux bonding driver mode that does not require any special network switch support. The outgoing network packet traffic is distributed according to the current load (computed relative to the speed) on each network interface slave. Incoming traffic is received by one currently designated slave network interface. If this receiving slave fails, another slave takes over the MAC address of the failed receiving slave.
Adaptive load balancing (balance-alb) Includes balance-tlb plus receive load balancing (rlb) for IPV4 traffic, and does not require any special network switch support. The receive load balancing is achieved by ARP negotiation. The bonding driver intercepts the ARP Replies sent by the local system on their way out and overwrites the source hardware address with the unique hardware address of one of the nic slaves in the single logical bonded interface such that different network-peers use different MAC addresses for their network packet traffic.
