I have a intergration with Cisco Catalyst. When the Service Now Mid Tier runs and comes across a device wth more than one serial Number it attempts to make them all individual CI's I have set he recon to run the switch apart from the Grand Parent which must use Serial Number for all devices to maintain uniqueness. Since we want Cisco to be the Primary Source or Truth we want Service Now Pattern matches to not use Serial but use Mac address as uniqueness and update where needed. Right now it is aborting becuase of the look up assocating Serial only. has anyone come across this condition and what did you do to get around it
