Configuring 802.1X port security
34
For example, to re-authenticate Clients connected to interface 3/1, enter the following command.
PowerConnect#dot1x re-authenticate e 3/1
Syntax: dot1x re-authenticate ethernet <port>
Specify the <port> variable in the following formats:
•
PowerConnect B-Series FCX stackable switches – <stack-unit/slotnum/portnum>
Setting the quiet period
If the Dell PowerConnect device is unable to authenticate the Client, the Dell PowerConnect device
waits a specified amount of time before trying again. The amount of time the Dell PowerConnect
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 Dell PowerConnect device
When the 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 PowerConnect 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 PowerConnect 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 PowerConnect 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 PowerConnect device waits before retransmitting the
EAP-request/identity frame to the Client.
For example, to cause the Dell PowerConnect device to wait 60 seconds before retransmitting an
EAP-request/identity frame to a Client, enter the following command.
PowerConnect(config-dot1x)#timeout tx-period 60
If the Client does not send back an EAP-response/identity frame within 60 seconds, the device will
transmit another EAP-request/identity frame.
Syntax: [no] timeout tx-period <seconds>
where <seconds> is a value from 1 – 4294967295. The default is 30 seconds.
