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.
Configuration guidelines
• 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.
• 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.
• If no critical VLAN is configured, RADIUS server unreachable can cause an online user being
re-authenticated to be logged off. If a critical VLAN is configured, the user remains online and in the
original VLAN.
