Configuring 802.1X port security
28
Syntax: [no] timeout re-authperiod <seconds>
The re-authentication interval is a global setting, applicable to all 802.1X-enabled interfaces. To
re-authenticate Clients connected to a specific port manually, use the dot1x re-authenticate
command. Refer to “Re-authenticating a port manually”, below.
Re-authenticating a port manually
When periodic re-authentication is enabled, by default the Dell device re-authenticates Clients
connected to an 802.1X-enabled interface every 3,600 seconds (or the time specified by the dot1x
timeout re-authperiod command). You can also manually re-authenticate Clients connected to a
specific port.
For example, to re-authenticate Clients connected to interface 1, enter the following command.
PowerConnect# dot1x re-authenticate e 1
Syntax: dot1x re-authenticate ethernet <portnum>
The <portnum> parameter is a valid port number.
Setting the quiet period
If the Dell device is unable to authenticate the Client, the Dell device waits a specified amount of
time before trying again. The amount of time the Dell device waits is specified with the quiet-period
parameter. The quiet-period parameter can be from 1 – 4294967295 seconds. The default is 60
seconds.
For example, to set the quiet period to 30 seconds, enter the following command.
PowerConnect(config-dot1x)# timeout quiet-period 30
Syntax: [no] timeout quiet-period <seconds>
Specifying the wait interval and number of EAP-request/
identity frame retransmissions from the
PowerConnect device
When the Dell device sends an EAP-request/identity frame to a Client, it expects to receive an
EAP-response/identity frame from the Client. By default, if the Dell device does not receive an
EAP-response/identity frame from a Client, the device waits 30 seconds, then retransmits the
EAP-request/identity frame. Also by default, the Dell device retransmits the EAP-request/identity
frame a maximum of two times. You can optionally configure the amount of time the device will
wait before retransmitting an EAP-request/identity frame, and the number of times the
EAP-request/identity frame will be transmitted. This section provides the command syntax for
these features.
Setting the wait interval for EAP frame retransmissions
By default, if the Dell device does not receive an EAP-response/identity frame from a Client, the
device waits 30 seconds, then retransmits the EAP-request/identity frame. You can optionally
change the amount of time the Dell device waits before retransmitting the EAP-request/identity
frame to the Client.
