Verifying a CSS Is Established

Verifying a CSS Is Established

After you complete the CSS configuration, check key indicators to determine whether the CSS has been established successfully. If the CSS has been successfully established, log in to the CSS and run commands to confirm the CSS status and configure enhanced CSS functions. If no CSS has been established, check the indicator abnormalities or log in to the CSS and run commands to locate and rectify faults.

Reviewing Indicators to Check Whether a CSS Is Established

Background

After a CSS is established, check the indicators on MPUs or CSS cards to view CSS status information, including the master/standby state of switches and link status.

Checking Whether Indicator Status Is Normal

Table 8-5 describes the indicator status after two switches establish a CSS successfully.

  • The CSS MASTER indicator on only one MPU is steady green, the MASTER indicators on all CSS cards installed on the same switch as the MPU are steady green, and the MASTER indicators on all CSS cards installed on the other switch is off.
  • On one switch, the CSS ID indicators numbered 1 on both MPUs are steady green. On the other switch, the CSS ID indicators numbered 2 on both MPUs are steady green.
  • The LINK/ALM indicators of ports on all CSS cards connected to cluster cables are steady green.

  • The CSS MASTER indicator on only one MPU is steady green.
  • CSS ID indicator 1 on an MPU of one switch and CSS ID indicator 2 on an MPU of the other switch are steady green.
  • The LINK/ALM indicators of ports on the SFUs connected to cluster cables are steady green.

  • The CSS MASTER indicator on only one MPU is steady green.
  • CSS ID indicator 1 on an MPU of one switch and CSS ID indicator 2 on an MPU of the other switch are steady green.
  • The LINK/ALM indicators of ports on the MPUs or SFUs connected to cluster cables are steady green.

For details about the indicator status and meanings, see Indicator Status in CSS Card Clustering.

Follow-Up Process
  • If the indicator status is normal, log in to the CSS and run commands to check CSS status information and configure enhanced CSS functions.

  • If the indicator status is abnormal, locate the fault according to Table 8-6 or log in to the CSS and run commands to locate and rectify the faults.

Indicator Status in CSS Card Clustering

Table 8-6 describes the indicators that show the status of a CSS set up by connecting CSS cards.

Description

All MPUs

CSS MASTER: master/standby status indicator

  • Steady green: The MPU is the master MPU of the CSS, and the local chassis is the master switch. The MASTER indicator is off on the standby switch. On the standby switch, the MPU with the ACT indicator steady on is the standby MPU of the CSS.

  • Off: The CSS function is not enabled or the local MPU is not the master MPU of the CSS.

CSS ID: CSS ID indicator

There are eight CSS ID indicators on the panel, but only one is on at a time.
  • CSS ID N is steady on: The CSS ID of the local chassis is N.

  • All CSS ID indicators are off: The chassis is not running the CSS service.

VS08 CSS card

MASTER: master/standby status indicator
  • Steady green: The local chassis is the master switch and the MASTER indicators on all the CSS cards in this chassis are steady on. All the MASTER indicators on the standby switch are off.

  • Off: The CSS function is not enabled or the local chassis is not the master chassis.

LINK/ALM: port status indicator
  • Steady green: The port is Up, and cable connection on the port is correct.

  • Steady red: Cable connection on the port is incorrect.

  • Off: The link status of the port is Down.

MPUB-integrated CSS card

SFUB-integrated CSS card

LINK/ALM: 10G optical port indicator

  • Steady green: The port is Up, and cable connection on the port is correct.

  • Steady red: Cable connection on the port is incorrect.

  • Off: The link status of the port is Down.

LINK/ALM: 40G optical port indicator

  • Steady green: The link status of all the internal four CSS ports is Up.
  • Steady yellow: The link status of some of the internal four CSS ports is Up, and the link status of others is Down.
  • Steady red: Cable connection on the port is incorrect.
  • Off: The link status of all the internal four CSS ports is Down.

A 40G optical interface is actually split into four 10G optical interfaces.

Logging In to a CSS to Verify that a CSS Is Established

Context

You can log in to a CSS and run display commands to check whether the CSS is established successfully. If the CSS fails to be established, you can locate the faults according to the command output.

Procedure

  1. Log in to the CSS.

    • Local login: Log in to the CSS from the console port on any MPU.
    • Remote login: After reachable routes are configured, you can remotely log in to the CSS from a management interface on any MPU or a Layer 3 interface using Telnet, STelnet, web, or SNMP.
    NOTE:
    • After a CSS is established successfully, the configuration file of the master switch takes effect. When logging in to a CSS remotely, access the IP address of the master switch.

    • If a CSS is not established, log in to the two member switches for troubleshooting.

  2. Check whether a CSS is established successfully.

    Run the display device command to check the card status. If the card status of two member switches is displayed in the command output, the CSS is established successfully.

    Alternatively, run the display css status command to check the CSS status. If CSS status of two member switches is displayed, the CSS is established successfully.

    • If the command output contains the status of cards on both switches, go to step 3.
    • If the command output contains the status of cards on only one switch, rectify the fault according to Checking Whether Cables Are Correctly Connected.

  3. Check whether the cluster links are normal.

    Run the display css channel command to check whether the cluster link connections are the same as the actual hardware connections.

    • If the displayed cluster link connections are the same as the actual hardware connections, all the cluster links are running normally and a CSS is established successfully.
    • If some cluster links are not displayed (abnormal cluster links), run the display css port brief command to check the status of all CSS ports.

    • If the CSS ports with abnormal cluster links are Up, the cluster cables may be connected incorrectly. Rectify the fault according to Checking Whether Cables Are Correctly Connected.
    • If the CSS ports with abnormal cluster links are Down, check whether the cluster cables on the ports are loose or damaged.

Rectifying Common CSS Faults
  • Checking Whether Cables Are Correctly Connected

    Run the terminal monitor and terminal trapping commands in the user view to enable the alarm function. Check whether an alarm on incorrect cluster cable connection is displayed.
    • S12704&S12708&12712: 1.3.6.1.4.1.2011.5.25.183.3.3.2.15 hwCssPhyVs08ConnectError
    • S12710: 1.3.6.1.4.1.2011.5.25.183.3.3.2.4 hwCssConnectError and 1.3.6.1.4.1.2011.5.25.183.3.3.2.19 hwCssPhyCardConnectError

    If no alarm is generated and the configuration is correct, a hardware fault may have occurred. For example, the MPU, SFU, or cluster cable is faulty.

    If such an alarm is displayed, connect cluster cables correctly according to the alarm message. You can obtain the following information from the alarm message:
    • CSS ID, slot ID, and number of the CSS port where the cluster cable is incorrectly connected
    • Correct connection of the cluster cable
