Pattern content discovery is discovering common switches and not next gereration switches which are not supported today.
Steps to Reproduce
Run discovery of the network switch and verify if the needed information is coming back.
If information is not coming back please verify with customer with Version of switches is he using.
If customer is using the next gereration switches it will is not supported from OOB.
Customer can still excute the pattern but it will only discover the common CIs (if SNMP query where not changed).
Pattern content discovery will discover only common switches and next gereration switches are not supported today.
