Example for Configuring Cluster Eth-Trunks

Example for Configuring Cluster Eth-Trunks

Networking Requirements

To simplify network structure and prevent network loops, core switches SwitchA and SwitchB set up a CSS to connect to upstream and downstream devices. The customer wants to expand the uplink bandwidth and requires that member switches in the CSS back up each other to improve reliability.

In Figure 3-37, a cluster Eth-Trunk can be configured for uplink ports of the CSS to expand the uplink bandwidth. SwitchC and SwitchD are dual homed to the CSS to improve reliability, and cluster Eth-Trunks can be configured for downlink ports of the CSS. In this example, the upstream and downstream devices of the CSS are Huawei S series switches.

Figure 3-37  Configuring cluster Eth-Trunks

Configuration Roadmap

  1. Configure a cluster Eth-Trunk between the CSS and its upstream device and add physical member ports to the Eth-Trunk to expand the uplink bandwidth.

  2. Configure cluster Eth-Trunks between the CSS and its downstream devices and add physical member ports to the Eth-Trunks, so that the member switches work in redundancy mode to improve network reliability.

  3. Enable Eth-Trunks to forward local traffic first to improve forwarding efficiency and reduce the load on the CSS cable between member switches. When an Eth-Trunk member port of a local device is working normally or when the traffic is not heavy, traffic is forwarded preferentially through the local member port.

Procedure

  1. Configure an Eth-Trunk between the CSS and its upstream device.

    # Configure an Eth-Trunk on the CSS and add uplink ports to the Eth-Trunk.

    <HUAWEI> system-view
    [HUAWEI] sysname CSS
    [CSS] interface eth-trunk 10
    [CSS-Eth-Trunk10] quit
    [CSS] interface gigabitethernet 1/1/0/4
    [CSS-GigabitEthernet1/1/0/4] eth-trunk 10
    [CSS-GigabitEthernet1/1/0/4] quit
    [CSS] interface gigabitethernet 2/1/0/4
    [CSS-GigabitEthernet2/1/0/4] eth-trunk 10
    [CSS-GigabitEthernet2/1/0/4] quit

    # Configure an Eth-Trunk on SwitchE and add member ports to the Eth-Trunk.

    <HUAWEI> system-view
    [HUAWEI] sysname SwitchE
    [SwitchE] interface eth-trunk 10
    [SwitchE-Eth-Trunk10] quit
    [SwitchE] interface gigabitethernet 1/0/1
    [SwitchE-GigabitEthernet1/0/1] eth-trunk 10
    [SwitchE-GigabitEthernet1/0/1] quit
    [SwitchE] interface gigabitethernet 1/0/2
    [SwitchE-GigabitEthernet1/0/2] eth-trunk 10
    [SwitchE-GigabitEthernet1/0/2] quit

  2. Configure Eth-Trunks between the CSS and its downstream devices.

    # Configure an Eth-Trunk on the CSS and add the downlink ports connected to SwitchC to the Eth-Trunk.

    [CSS] interface eth-trunk 20
    [CSS-Eth-Trunk20] quit
    [CSS] interface gigabitethernet 1/1/0/3
    [CSS-GigabitEthernet1/1/0/3] eth-trunk 20
    [CSS-GigabitEthernet1/1/0/3] quit
    [CSS] interface gigabitethernet 2/1/0/5
    [CSS-GigabitEthernet2/1/0/5] eth-trunk 20
    [CSS-GigabitEthernet2/1/0/5] quit

    # Configure an Eth-Trunk on SwitchC and add member ports to the Eth-Trunk.

    <HUAWEI> system-view
    [HUAWEI] sysname SwitchC
    [SwitchC] interface eth-trunk 20
    [SwitchC-Eth-Trunk20] quit
    [SwitchC] interface gigabitethernet 1/0/1
    [SwitchC-GigabitEthernet1/0/1] eth-trunk 20
    [SwitchC-GigabitEthernet1/0/1] quit
    [SwitchC] interface gigabitethernet 1/0/2
    [SwitchC-GigabitEthernet1/0/2] eth-trunk 20
    [SwitchC-GigabitEthernet1/0/2] quit

    # Configure an Eth-Trunk on the CSS and add the downlink ports connected to SwitchD to the Eth-Trunk.

    [CSS] interface eth-trunk 30
    [CSS-Eth-Trunk30] quit
    [CSS] interface gigabitethernet 1/1/0/5
    [CSS-GigabitEthernet1/1/0/5] eth-trunk 30
    [CSS-GigabitEthernet1/1/0/5] quit
    [CSS] interface gigabitethernet 2/1/0/3
    [CSS-GigabitEthernet2/1/0/3] eth-trunk 30
    [CSS-GigabitEthernet2/1/0/3] quit

    # Configure an Eth-Trunk on SwitchD and add member ports to the Eth-Trunk.

    <HUAWEI> system-view
    [HUAWEI] sysname SwitchD
    [SwitchD] interface eth-trunk 30
    [SwitchD-Eth-Trunk30] quit
    [SwitchD] interface gigabitethernet 1/0/1
    [SwitchD-GigabitEthernet1/0/1] eth-trunk 30
    [SwitchD-GigabitEthernet1/0/1] quit
    [SwitchD] interface gigabitethernet 1/0/2
    [SwitchD-GigabitEthernet1/0/2] eth-trunk 30
    [SwitchD-GigabitEthernet1/0/2] quit

  3. Enable local preferential forwarding on the Eth-Trunks. By default, local preferential forwarding is enabled on an Eth-Trunk.

    [CSS] interface eth-trunk 10
    [CSS-Eth-Trunk10] local-preference enable
    [CSS-Eth-Trunk10] quit
    [CSS] interface eth-trunk 20
    [CSS-Eth-Trunk20] local-preference enable
    [CSS-Eth-Trunk20] quit
    [CSS] interface eth-trunk 30
    [CSS-Eth-Trunk30] local-preference enable
    [CSS-Eth-Trunk30] quit
    [CSS] quit
    

  4. Verify the configuration.

    After the configuration is complete, run the display trunkmembership eth-trunk command in any view to view information about Eth-Trunk member ports.

    The command output shows information about member ports in Eth-Trunk 10.

    <CSS> display trunkmembership eth-trunk 10
    Trunk ID: 10
    Used status: VALID
    TYPE: ethernet
    Working Mode : Normal
    Number Of Ports in Trunk = 2
    Number Of Up Ports in Trunk = 2
    Operate status: up
    Interface GigabitEthernet1/1/0/4, valid, operate up, weight=1
    Interface GigabitEthernet2/1/0/4, valid, operate up, weight=1
