Example for Establishing a CSS (Using CSS Cards)

Example for Establishing a CSS (Using CSS Cards)

Networking Requirements

An enterprise needs to build a network that has a reliable core layer and simple structure to facilitate configuration and management.

In Figure 3-35, SwitchA and SwitchB at the core layer set up a CSS through CSS card connections. 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. In this example, the core switches are the S7706 switches.

Figure 3-35  Establishing a CSS

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 to CSS card connection 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 has been 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 about how to install the hardware, 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
    

    # 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 has been established successfully.

    # View the indicator status.

    If the MASTER indicator on a CSS card of SwitchA is steady on, the MPU with the CSS card installed is the master MPU and SwitchA is the master switch.

    If the MASTER indicator on a CSS card of SwitchB is off, SwitchB is the standby switch.

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