Enabling the quiet timer
The quiet timer enables the network access device to wait a period of time before it can process any
authentication request from a client that has failed an 802.1X authentication.
You can set the quiet timer to a high value in a vulnerable network or a low value for quicker
authentication response.

Enabling the periodic online user re-authentication function
Periodic online user re-authentication tracks the connection status of online users and updates the
authorization attributes assigned by the server, such as the ACL, VLAN, and user profile-based QoS. The
re-authentication interval is user configurable.

The periodic online user re-authentication timer can also be set by the authentication server in the session-
timeout attribute. The server-assigned timer overrides the timer setting on the access device, and enables
periodic online user re-authentication, even if the function is not configured. Support for the server
assignment of re-authentication timer and the re-authentication timer configuration on the server vary with
servers.
NOTE:
The VLAN assignment status must be consistent before and after re-authentication. If the authentication
server has assigned a VLAN before re-authentication, it must also assign a VLAN at re-authentication.
If the authentication server has assigned no VLAN before re-authentication, it must not assign one at re-
authentication. Violation of either rule can cause the user to be logged off. The VLANs assigned to an
online user before and after re-authentication can be the same or different.
