after a user passes the authentication/authorization begins being accounted, the switch
prompts that the user has been online when the user logs into the switch before CAMS
makes online detection. Therefore, the user cannot access network resources normally.
The user can access the network only after the network administrator deletes manually
the online information of the user.
To solve this problem, user re-authentication at reboot is designed. After this function is
enabled, each time the switch reboots,
z The switch generates an Accounting-On message, which mainly includes NAS-ID,
NAS-IP (source IP) and session ID;
z The switch sends to CAMS an Accounting-On message;
z Upon receiving the CAMS Accounting-On message, CAMS finds and deletes the
existing online information of the user based on the NAS-ID, NAS-IP (source IP)
and session ID in the Accounting-On message.
 Note:
The main attributes of the Accounting-On message –– NAS-ID, NAS-IP and session ID
are often generated automatically by the switch. However, you can configure the
NAS-IP using the nas-ip command. Make sure you set a correct and valid NAS-IP
address. Otherwise, the switch automatically selects the IP address of the virtual VLAN
interface as NAS-IP.
