Session Reauthentication
The AAA server typically generates a session reauthentication request when a host with an unknown identity
or posture joins the network and is associated with a restricted access authorization profile (such as a guest
VLAN). A reauthentication request allows the host to be placed in the appropriate authorization group when
its credentials are known.
To initiate session authentication, the AAA server sends a standard CoA-Request message which contains a
Cisco VSA in this form: Cisco:Avpair=“subscriber:command=reauthenticate” and one or more session
identification attributes.
The current session state determines the switch response to the message. If the session is currently authenticated
by IEEE 802.1x, the switch responds by sending an EAPoL (Extensible Authentication Protocol over Lan)
-RequestId message to the server.
If the session is currently authenticated by MAC authentication bypass (MAB), the switch sends an
access-request to the server, passing the same identity attributes used for the initial successful authentication.
If session authentication is in progress when the switch receives the command, the switch terminates the
process, and restarts the authentication sequence, starting with the method configured to be attempted first.
If the session is not yet authorized, or is authorized via guest VLAN, or critical VLAN, or similar policies,
the reauthentication message restarts the access control methods, beginning with the method configured to
be attempted first. The current authorization of the session is maintained until the reauthentication leads to a
different authorization result.
Session Reauthentication in a Switch Stack
When a switch stack receives a session reauthentication message:
•
It checkpoints the need for a re-authentication before returning an acknowledgment (ACK).
•
It initiates reauthentication for the appropriate session.
•
If authentication completes with either success or failure, the signal that triggered the reauthentication
is removed from the stack member.
•
If the stack master fails before authentication completes, reauthentication is initiated after stack master
switch-over based on the original command (which is subsequently removed).
•
If the stack master fails before sending an ACK, the new stack master treats the re-transmitted command
as a new command.
