Why do I have over 500,000 Switch Forwarding & Rule Switchport CI's in CMDB?

[Balaji Chandras]

I only have about 10000 computers, servers, and network devices in the CMDB, but have over 500,000 of Switch Forwarding Rule and Switchport CI's.   Is this normal, or is there something I don't have configured right?

Hi @Balaji Chandras,
the structure and amount of your CI's strongly depends on your infrastructure setup. 

If you use Discovery, a huge amount of CI's may be created and maintained. Per se, there is nothing wrong with that. I am still surprised sometimes what discovery can bring to light 🙂

If you still have some doubts you should check with you IT Infrastructure/Network team and review your CI's. Hope this helps a bit.

In order to stop data to be collected on forwarding rules, and CI's being created we can disable the corresponding sensor reacting to the probe. 

Probe: SNMP - Switch - Forwarding table - https://<instance-name>.service-now.com/nav_to.do?uri=discovery_probes_snmp.do?sys_id=409d4625eb31310020ee20b6a206fe0b
