Identification sections in pattern failed

[Sebastian18]

Hey guys,

so I´m trying to discover some CISCO Switches via SNMP.

The credential-test succeeds, so this problem should not be either the credentials nor the connection itself.

But if try to discover them, I´ll get the following error report:

Identifizierungsmodul: Discovery-Status ist FEHLER Identification sections in pattern failed: section: discovery, error: All command implementations (SNMP_TABLE) failed on host 10.21.96.251. Host might be down or unreachable. ()

I´ve attached two screenshots regarding the error logs.

If you need any further details, let me know!

Thank you all in advance!

Before you do anything else, I would recommend you check the SNMP OID Classification table.

...\nav_to.do?uri=%2Fdiscovery_snmp_oid_list.do%3Fsysparm_userpref_module%3D6d95d1380a0a0b0200a27fb1e8b5b214%26sysparm_clear_stack%3Dtrue

Make sure you have an appropriate record therein matching the OID of the device you are discovering.

Hey Curtis,

you´re right, I was missing the correct OID.

So I added that one and tried again but got the same result. No CI has been discovered / created...

Added a SS of the OID-Entry.

Hello Sebastian,

I had the same issue. There is a workaround resolution. Check out the knowledge base article KB0866577. I have included link for it below;

Known Error - Network Switch Pattern Fails at various stages (servicenowservices.com)

Hope this will help.

Hey Sedat, thanks for your answer!

I´ve checked the document. 
On page one it says:

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 )

I´ve checked my network switch pattern and I´m missing all of points mentioned above (as shown in the screenshot) - so I can´t edit them.

Did you ever get this issue resolved?  I am having the same issue.
