Technical Tip: Host record creation methods
Description
This article describes about host record creation methods.
Solution
Rogue host records are created if any one of the following scenarios occur:
- Connected switch is L2 Polled by the appliance
- Connected switch sends a Link State Trap (which triggers the L2 Poll)
- Connected switch sends a MAC Notification Trap
The following methods will create host records regardless if connected switch is modeled in Topology/Inventory:
- DHCP fingerprint for the host is received on eth0 of appliance
- If connected switch is not in Topology/Inventory, adapter record will display offline with a blank Location field
- To verify if DHCP fingerprint was received, search for MAC address. Refer to the appropriate Administration Guide for details:
- Version 8.x: Hosts - > Device Identity
- Version 9.x: Users & Hosts - > Endpoint Fingerprints
- If fingerprint with an invalid MAC address is received, a rogue record will not be created.
- An Agent is installed on the host and communicates with the appliance.
