Configuring 802.1X Port Authentication
– 363 –
◆ Quiet Period – Sets the time that a switch port waits after the Max Request
Count has been exceeded before attempting to acquire a new client.
(Range: 1-65535 seconds; Default: 60 seconds)
◆ 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 296.)
◆ 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 171) and mapped on each port (See “Configuring Network Access for
Ports” on page 318).
