How to run a basic health check on a Connectrix B-Series switch.


For initial diagnosis, running the supportshow command gathers the output from various commands.

If further investigation is needed, it may become necessary to run a supportsave as it contains the supportshow and additional information for engineering and attach it to the appropriate service request.

To collect the supportshow, see EMC Knowledgebase solution:
489144: Connectrix: How to collect a switch log file with a Putty session step by step.
Connectrix: How to collect a switch log file with a PuTTY session, step by step


Once supportshow has been completed, open the file with any text file editor. Listed below are the most useful commands that are part of the supportshow output.


Additional Information

Enter commands in lowercase only; mixed case is for readability.
- Examples are based on Fabric OS 8.2.x or higher, see the support by Product page (also for older firmware outputs): search for the product in questions, and check for the command guide in the documentation section.
- For detailed explanation of the commands sees also the command guide for the relevant Fabric OS version.

  1. Verify that the switch is Dell Technologies supported.

    This command inventories and displays the FRU header content for each object in the chassis and chassis backplane
    It provides details about the CHASSIS, FAN, POWER SUPPLY, SW BLADE (switch), CP BLADE (control processor), and WWN UNIT.
    This output is most useful to confirm this is a Dell Technologies supported switch, using its Serial Number.
    If it is a Dell Technologies switch, there are two places to check.
First, scroll to the output labeled WWN Unit: 1 and view the ID Field.
It should be nine characters long and there are different varieties. 
Most of them are beginning with the letters EMC. Second, two lines below is the field Serial Num
All Dell Technologies Connectrix B-Series switch SN's should begin with the letters BRC

WWN  Unit: 1
ED-8510_4S_001:FID128:admin> chassishow
WWN Unit: 1
Header Version: 2
Part Num: CONTRX0000DCX
  1. Firmware: Verify that the firmware is supported.

    This displays the Fabric OS versions on primary and secondary partitions. For systems with multiple control processor (CP) cards and AP blades, this command displays this information for both local and remote CPs and the AP blades. After verifying the firmware level, you can confirm that the code is currently DELL EMC supported using the Dell support site (look for the asset and check the availability of the code.).
Firmware inconsistencies can cause various issues and if switch firmware has gone EOSL, it is recommended that the customer schedule an upgrade to the Target (T) code.

  1. Switch Health:
    If the switch is Dell Technologies supported, and the firmware is a supported level, search for the following commands to verify switch health.
Note that the command guide (can be downloaded from the same support site above.) of each version of code gives a comprehensive explanation and examples.

- Monitoring and Alerting Policy Suite (MAPS) In Fabric OS 8.2.x and later use the command:
This command displays a summary of the events or rules triggered and the objects on which the rules were triggered over a specified period of time.
mapsdb --show
Dashboard Information:
Displays the dashboard start time, active policies, configured alerts, fenced ports, decommissioned ports, and the quarantined ports.

Switch Health Report:
Displays the overall status of the switch. If the overall status is not healthy, the contributing factors and the fenced ports are listed.

Summary Report:
Displays the status of the monitoring categories determine the current health of the switch. The health state of each category is contributed to by a group of monitoring systems or error counters, and the rules configured in the active policy.
The summary view displays the following information for each category: information collected since midnight of the current day and the historical information collected over the last 7 days.

The health state can be one of the following:
No Error No error has occurred.

In operating range: The errors are within the thresholds configured in the active policy.

Out of operating range: The errors are above the configured thresholds, and this triggers the rules configured in the active policy. This indicates that some attributes of the switch are operating out of the configured range.

Rules Affecting Health: Displays the conditions that contributed to the current switch status. The following information is displayed: number of rules triggered in a category, repeat count, triggered rules, execution time, the elements for which rules were triggered, and the triggered value.

History Data: Displays the following historical data for a specific time window: the monitoring system, the current value that triggered the rule, and the elements for which rules were triggered.

History Data for Backend ports: Displays the error statistics for the backend ports for a specific time window.
If no operands are specified, this command displays the usage.

UNKNOWN - The blade is inserted but its state cannot be determined.
  • errDump
    This command displays external error log messages for all switch instances and the chassis, without any page breaks.

If you are dealing with a dial home service request, this is where you can find the error that caused the dial home.
The errors are logged chronologically from top to bottom (oldest to newest), so if the switch dialed home, chances are the correlating error message is found closer to the bottom of the errdump output.
Each message displays the following:

Timestamp - Timestamp for the message.
Message ID - Message identifier.
External sequence number - Sequence number for the message
Security audit flag - Security audit logged. AUDIT displays in the field.
Severity - Severity of the message. Valid values include INFO, WARNING, ERROR, and CRITICAL.
Switch name - Switch name for the generator of this message, or chassis.
Message - Message body.

  • haDump 
    haredundancy --show
    Only for use on Enterprise Directors. Use this command to display information about the status of the High Availability (HA) feature on the switch or a chassis. This command displays the following information:

Time Stamp
Local CP state (slot number and CP ID)
Remote CP state (slot number and CP ID)

Type of recovery (warm or cold)
High Availability (enabled or disabled)
Heartbeat (up or down)

Health of standby CP (healthy, failed, or unknown), is defined as follows:
Healthy - The standby CP is running and the background health diagnostic has not detected any errors.
Failed - The standby CP is running, but the background health diagnostic has discovered a problem with the blade. The logs should be checked to determine the appropriate repair action. Failover is disabled until the standby CP is repaired. Information about the failing device in the standby CP will be displayed.
Unknown - The standby CP health state is unknown due because the standby CP does not exist, heartbeat is down, or Health Monitor detects a configuration file error.

HA synchronization status:
HA State Synchronized - The system is currently fully synchronized. If a failover became necessary, it would be non-disruptive.
HA State Not In Sync - The system is unable to synchronize the two CPs because the standby CP is faulty, a haSyncStop command was issued, or a system error occurred. If a failover became necessary, currently, the standby CP reboots, and the failover is disruptive.
IP and Fibre Channel addresses configured for the switch.
Other internal HA state information, subject to change.
