Edit Tab

In blue below is the crucial information: mac address, the status (which must be active if a device is allowed access) and the vlan assigned.
The red box is information about when the end-device was last seen, and where.

All other fields are informational, and thus an option. You need to decide what is best for your environment. We come back to the Edit Tab in more detail later
There are several optional modules (nmap, static inventory, patch cables, McAfee Anti-virus), if these are not enabled in your environment, they will be disabled or invisible.

Device expiry: With v2.2, one can set an expiry date for devices in NAC. This may be useful in limiting how long external visitors have access.
When an expired device is detected, its is set to the "killed" state, and an email alert is sent. In the killed state the device is blocked, but no alerts are sent.

Status: Is this system enabled, not yet authorised, not actively managed by NAC, or to be explicitly denied?

DNS forward/reverse lookups are used to verify naming consistency. The 'copy' button write the DNS name as the system name.
