A 911 PSAP must inventory campus switches in Catalyst Center with working credentials before those devices can be assigned fabric roles. Why is discovery and inventory a prerequisite?
Select an answer to reveal the explanation.
Short Explanation
You can’t promote a switch to fabric edge if the controller doesn’t even know it exists. Discovery and inventory are the “check-in at the front desk” step—credentials, reachability, software facts—before roles and intent land. Skip it and fabric provisioning has nowhere to push.
Full Explanation
Cisco Catalyst Center must discover devices, collect inventory, and establish manageable connectivity (credentials/SNMPv3/SSH as designed) before fabric provisioning workflows can assign roles or push underlay/overlay configuration. Discovery is therefore a prerequisite operational step, not an optional report. DHCP-only role assignment or skipping inventory is inconsistent with controller-based SD-Access workflows.
