Network Switch Pattern fails at various stages at SNMP provider on subsequent queriesDescriptionMainly 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"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: < IP >. command type: SNMP_TABLE. command track:SnmpTableCommand\(Relevant) WorkaroundThis 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 Related Problem: PRB1378161
