Example for Establishing a CSS

Example for Establishing a CSS

Networking Requirements

An enterprise network requires high reliability on the core layer, but a simple network structure is required to facilitate configuration and maintenance.

As shown in Figure 8-32, two S12700s SwitchA and SwitchB at the core layer set up a CSS by connecting the CSS cards on the SFUs. SwitchA and SwitchB are the master switch and standby switch respectively. Switches at the aggregation layer connect to the CSS through Eth-Trunks and the CSS connects to the upstream network through an Eth-Trunk.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Install CSS cards on SwitchA and SwitchB, and connect cluster cables.
  2. Set the connection mode on SwitchA and SwitchB and set their CSS IDs and priorities to 1 and 2, 100 and 10 respectively, so SwitchA has a higher probability to be the master switch.
  3. Enable the CSS function on SwitchA and then on SwitchB to ensure that SwitchA becomes the master switch.
  4. Check whether a CSS is established successfully.
  5. Configure downlink Eth-Trunks for the CSS to improve forwarding bandwidth and reliability. (The detailed configuration is omitted in this example. For details about how to configure Eth-Trunks, see Example for Configuring Cluster Eth-Trunks.)

Procedure

  1. Install hardware.

    Install CSS cards on SwitchA and SwitchB, and connect cluster cables. For details, see Installing Hardware and Connecting Cluster Cables.

  2. Configure the CSS ID, CSS priority, and CSS connection mode for SwitchA and SwitchB.

    # Set the CSS ID, CSS priority, and CSS connection mode to 1, 100, and CSS card connection for SwitchA.

    <HUAWEI> system-view
    [HUAWEI] sysname SwitchA
    [SwitchA] set css mode css-card
    [SwitchA] set css id 1
    [SwitchA] set css priority 100
    

    # Set the CSS ID, CSS priority, and CSS connection mode to 2, 10, and CSS card connection for SwitchB.

    <HUAWEI> system-view
    [HUAWEI] sysname SwitchB
    [SwitchB] set css mode css-card
    [SwitchB] set css id 2
    [SwitchB] set css priority 10
    
    NOTE:

    To use two switches to set up a CSS using integrated CSS cards (providing two types of CSS ports: 4*10G and 40G ports), you need to run the css port media-type command to set the CSS port type to the actual port type used for cluster connections.

    # Check the CSS configuration.

    NOTE:

    After the configuration is complete, run the display css status saved command to check the CSS configuration.

    # Check the CSS configuration on SwitchA.

    [SwitchA] display css status saved
    Current Id   Saved Id     CSS Enable   CSS Mode    Priority    Master force     
    ------------------------------------------------------------------------------  
    1            1            Off          CSS card    100         Off             

    # Check the CSS configuration on SwitchB.

    [SwitchB] display css status saved
    Current Id   Saved Id     CSS Enable   CSS Mode    Priority    Master force     
    ------------------------------------------------------------------------------  
    1            2            Off          CSS card    10          Off              

  3. Enable the CSS function.

    # Enable the CSS function on SwitchA and restart SwitchA.

    [SwitchA] css enable
    Warning: The CSS configuration will take effect only after the system is rebooted. T
    he next CSS mode is CSS card. Reboot now? [Y/N]:y

    # Enable the CSS function on SwitchB and restart SwitchB.

    [SwitchB] css enable
    Warning: The CSS configuration will take effect only after the system is rebooted. T
    he next CSS mode is CSS card. Reboot now? [Y/N]:y

  4. Check whether a CSS is established successfully.

    # View the indicator status.

    The CSS MASTER indicator on an MPU of SwitchA is steady on, indicating that the MPU is the system master MPU and SwitchA is the master switch.

    The CSS MASTER indicator on an MPU of SwitchB is off, indicating that SwitchB is the standby switch.

    # Log in to the CSS through the console port on any MPU to check whether the CSS is established successfully.
