Adding Member Interfaces to an Eth-Trunk

Adding Member Interfaces to an Eth-Trunk

Context

Before adding member interfaces to an Eth-Trunk, you need to learn about the configuration notes. See Licensing Requirements and Limitations for Link Aggregation.

When member interfaces on the same switch are added to an Eth-Trunk, they can be aggregated in intra-card or inter-card mode. In inter-card aggregation mode, member interfaces can be aggregated between cards with Eth-Trunk specification extension, between cards with and without Eth-Trunk specification extension, and between cards without Eth-Trunk specification extension. Table 3-8 compares the link aggregation modes.
Table 3-8  Modes for aggregating member interfaces on the same switch

Link Aggregation Mode

Advantage

Precautions

Intra-card

Higher bandwidth, higher reliability, and load balancing, which are the same as those of link aggregation

When the card is faulty, traffic on the Eth-Trunk interface is interrupted.

Inter-card

Between cards with Eth-Trunk specification extension

  • Higher bandwidth, higher reliability, and load balancing, which are the same as those of link aggregation

  • Eth-Trunk member interfaces are located on different cards. When a card is faulty, traffic on the faulty card is switched to the normal cards. Therefore, inter-card link aggregation has higher reliability than intra-board link aggregation.

The cards on which Eth-Trunk member interfaces are located must use the same hash mode.

Between cards with and without Eth-Trunk specification extension

The hash mode must be set to normal for cards with Eth-Trunk specification extension.

Between cards without Eth-Trunk specification extension

N/A

You can run the display eth-trunk load-balance hash-mode command to check the hash mode of a card.

NOTE:

On the card with Eth-Trunk specification extension, if the index of the Eth-Trunk is larger than 127 or the Eth-Trunk has more than eight member interfaces, the hash mode cannot be changed to normal. You can run the display trunk index-map command to check the index of an Eth-Trunk.

Cards with Eth-Trunk specification extension refer to the following cards:

  • S7700: FC series, SC series, EE series, and X series cards

  • S9700: FC series, SC series, EE series, X series, and EH1D2X48SEC0 cards

Figure 3-21  Recommended deployment mode (when the member interfaces of multiple Eth-Trunks are deployed on different cards)
Figure 3-22  Deployment mode that is not recommended (when the member interfaces of multiple Eth-Trunks are deployed on different cards)

You can add member interfaces to an Eth-Trunk in the Eth-Trunk interface view or member interface view.

Procedure

  • Add member interfaces to an Eth-Trunk in the Eth-Trunk interface view.
    1. Run system-view

      The system view is displayed.

    2. (Optional) Run eth-trunk load-balance hash-mode { advanced | normal } slot slot-id

      A hash mode of the card is configured so that interfaces on the card can form an Eth-Trunk with interfaces on another card.

      NOTE:

      Only the card with Eth-Trunk specification extension supports the hash mode configuration.

    3. Run interface eth-trunk trunk-id

      The Eth-Trunk interface view is displayed.

    4. (Optional) Run mixed-rate link enable

      Interfaces with different rates are allowed to be added to the same Eth-Trunk.

      By default, interfaces with different rates are not allowed to be added to the same Eth-Trunk.

    5. Run trunkport interface-type { interface-number1 [ to interface-number2 ] } &<1-8> [ mode { active | passive } ]

      A member interface is added to the Eth-Trunk.

      NOTE:

      When you add member interfaces to an Eth-Trunk in a batch, if one interface fails to be added to the Eth-Trunk, subsequent interfaces in the batch cannot be added to the Eth-Trunk.

  • Add member interfaces to an Eth-Trunk in the member interface view.
    1. Run system-view

      The system view is displayed.

    2. (Optional) Run eth-trunk load-balance hash-mode { advanced | normal } slot slot-id

      A hash mode of the card is configured so that interfaces on the card can form an Eth-Trunk with interfaces on another card.

    3. (Optional) Interfaces with different rates are allowed to be added to the same Eth-Trunk.

      1. Run the interface eth-trunk trunk-id command to enter the Eth-Trunk interface view.

      2. Run the mixed-rate link enable command to allow the device to add interfaces with different rates to the same Eth-Trunk.

        By default, interfaces with different rates are not allowed to be added to the same Eth-Trunk.

      3. Run the quit command to return to the system view.

    4. Run interface interface-type interface-number

      The member interface view is displayed.

    5. Run eth-trunk trunk-id [ mode { active | passive } ]

      The member interface is added to an Eth-Trunk.

    When adding an interface to an Eth-Trunk, pay attention to the following points:

    • An Ethernet interface can be added to only one Eth-Trunk. To add an Ethernet interface to another Eth-Trunk, delete it from the original one first.
    • After interfaces are added to an Eth-Trunk, the Eth-Trunk learns MAC addresses and ARP entries but member interfaces do not.
    • Before deleting an Eth-Trunk, delete member interfaces from the Eth-Trunk.
