Configuring 802.1X Port Authentication
– 342 –
•
Tx Period – Sets the time period during an authentication session that
the switch waits before re-transmitting an EAP packet.
(Range: 1-65535; Default: 30 seconds)
•
Supplicant Timeout – Sets the time that a switch port waits for a
response to an EAP request from a client before re-transmitting an EAP
packet. (Range: 1-65535; Default: 30 seconds)
This command attribute sets the timeout for EAP-request frames other
than EAP-request/identity frames. If dot1x authentication is enabled on
a port, the switch will initiate authentication when the port link state
comes up. It will send an EAP-request/identity frame to the client to
request its identity, followed by one or more requests for authentication
information. It may also send other EAP-request frames to the client
during an active connection as required for reauthentication.
•
Server Timeout – Sets the time that a switch port waits for a response
to an EAP request from an authentication server before re-transmitting
an EAP packet. (Default: 0 seconds)
A RADIUS server must be set before the correct operational value of 10
seconds will be displayed in this field. (See “Configuring Remote Logon
Authentication Servers” on page 264 .)
•
Re-authentication Status – Sets the client to be re-authenticated
after the interval specified by the Re-authentication Period. Re-
authentication can be used to detect if a new device is plugged into a
switch port. (Default: Disabled)
•
Re-authentication Period – Sets the time period after which a
connected client must be re-authenticated. (Range: 1-65535 seconds;
Default: 3600 seconds)
•
Re-authentication Max Retries – The maximum number of times the
switch port will retransmit an EAP request/identity packet to the client
before it times out the authentication session. (Range: 1-10;
Default: 2)
•
Intrusion Action – Sets the port’s response to a failed authentication.
•
Block Traffic – Blocks all non-EAP traffic on the port. (This is the
default setting.)
•
Guest VLAN – All traffic for the port is assigned to a guest VLAN.
The guest VLAN must be separately configured (See “Configuring
VLAN Groups” on page 150 ) and mapped on each port (See
“Configuring Network Access for Ports” on page 285 ).
