Network Switch Pattern fails at various stages at SNMP provider on subsequent queries - Known Error

Network Switch Pattern fails at various stages at SNMP provider on subsequent queries Description Mainly this is noticed with the following error on the "SNMP Switch" pattern:

Error : "all commands failed on host: . 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" Steps to Reproduce

Run a discovery on a switch. Notice the "Network Switch" pattern fails in discovery logs.

Review the pattern logs. Find the following failure on the step with the error: all commands failed on host: . command type: SNMP_TABLE. command track: SnmpTableCommand\(Relevant) Workaround 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 S elect 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
