Mainly this is noticed with the following error on the "SNMP Switch" pattern:

Error : "all commands failed on host: < IP >. command type: SNMP_TABLE. command track:
SnmpTableCommand\(Relevant)"

The steps that seem to fail are :

• 35.17 Handle FDB for Cisco ( SNMP-Switch-Vlan )
• 35.30. Handle bridge ports for Cisco ( Cisco_SNMP-Switch-Vlan )
• 35.34. Handle STP for Cisco ( Cisco_SNMP-Switch-Vlan )
• 39.1   Get entPhysicalTable1 ( Stacked Switches )
• 39.14  Do Slaves Have A Name ( Stacked Switches )

UPDATE:

- Also include systemObjectID, this is not included in images: "1.3.6.1.4.1.9.1.1208"

- The precondition logic is incorrect. The condition should be $PRB1378161 NOT EQUALS "true".

-- Because we do not set the variable to false, it is null. So the condition "$PRB1378161 EQUALS false" (null===false) will not be passed.

Some device systemObjectIDs that are impacted seems to be:

• "1.3.6.1.4.1.9.1.1745"
• "1.3.6.1.4.1.9.1.2494"
• "1.3.6.1.4.1.9.1.1287"
• "1.3.6.1.4.1.9.1.1226"
• "1.3.6.1.4.1.9.1.283"
• "1.3.6.1.4.1.9.1.2501"
• "1.3.6.1.4.1.9.1.1934"
• "1.3.6.1.4.1.9.1.516"
• "1.3.6.1.4.1.9.1.1732"

1. Run a discovery on a switch.
   Notice the "Network Switch" pattern fails in discovery logs.
   
   
2. Review the pattern logs. Find the following failure on the step with the error:
   

   all commands failed on host: < IP >. command type: SNMP_TABLE. command track:
   SnmpTableCommand\(Relevant)

This problem is fixed in an upcoming release. If you are able to upgrade, review the Fixed In section to determine the latest version with a permanent fix your instance can be upgraded to.

If an upgrade is not possible and the symptoms are seen as reported in description, add/update the below steps as a workaround:

• Add a new step 1.48 after 1.47 : "Get sysObjectID".
• In the new step 1.48 

                         Select Operation = "Set parameter value

                         Check "precondition" check box

                        Select Meet=Any

                        Add all the above SysObjectIDs as shown in the below screenshot.

 

 

• Updated below steps preconditions with PRB1378161 variable added in 1.48 :  
  
  
  
  • Step : 35.17 Handle FDB for Cisco ( SNMP-Switch-Vlan ) ------- Add ($PRB1378161 equals false) in the condition as shown in the below image.

 

 

• • Step : 35.30. Handle bridge ports for Cisco ( Cisco_SNMP-Switch-Vlan ) --- Add ($PRB1378161 equals false) in the condition as shown in the below image
    (Please only Add ($PRB1378161 equals false) apart from your OOTB as the below image shows the Orlando pattern - this step is different in Paris)

 

 

• • Step 35.35 : Handle STP for Cisco ( Cisco_SNMP-Switch-Vlan ) - Add ($PRB1378161 equals false) in the condition as shown in the below image

 

 

• • Step : 39.1   Get entPhysicalTable1 ( Stacked Switches ) - Add ($PRB1378161 equals false) in the condition as shown in the below image

 

 

• • Step : 39.14  Do Slaves Have A Name ( Stacked Switches ) - Add ($PRB1378161 equals false) in the condition as shown in the below image
