CI getting classified into incorrect class

[Asmita7]

Hello friends,

I am facing an issue with discovery. 

Some SNMP devices are getting classified into incorrect class. It should be classified as a switch but is classified as a Router. What can be the reason ?

Please suggest

Thanks,

Asmita

The 'SNMP - Classify Initialization' pattern is used to determin what type of CI an SNMP device should be. 

The variables you should review conditions for are '

"isSwitch" and "isRouter"

Part of the conditions is querying this table: discovery_snmp_oid and updating the variable based on matches. 

In the first instance, have you reviewed your discovery pattern logs to understand why a device has been classified as a Router rather than a Switch? 

Please do share these if you want further help.

Hi @Asmita7 ,
Please navigate to SNMP System OID table and search for the OID which is being returned from the device. There you will find the record and then there you can select the correct table as Router and classifier as "Standard Network Router". Try running the discovery again and it should classify correctly.

Please mark the answer as helpful/correct if it helps.

Thanks,

@Asmita7 What is theOID of the device you are trying to classify? Once you get that, check in the table 'discovery_snmp_oid ' for that. Basing on this entry, the device will be classified.
