Configuring 802.1X port security

For example, to cause the Dell 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.
Setting the maximum number of EAP frame retransmissions
The Dell device retransmits the EAP-request/identity frame a maximum of two times. If no
EAP-response/identity frame is received from the Client after two EAP-request/identity frame
retransmissions (or the amount of time specified with the auth-max command), the device restarts
the authentication process with the Client.
You can optionally change the number of times the Dell device should retransmit the
EAP-request/identity frame. You can specify between 1 – 10 frame retransmissions. For example,
to configure the device to retransmit an EAP-request/identity frame to a Client a maximum of three
times, enter the following command:
PowerConnect(config-dot1x)# auth-max 3
Syntax: auth-max <value>
<value> is a number from 1 – 10. The default is 2.
Specifying the wait interval and number of EAP-request/
identity frame retransmissions from the RADIUS server
Acting as an intermediary between the RADIUS Authentication Server and the Client, the Dell
device receives RADIUS messages from the RADIUS server, encapsulates them as EAPOL frames,
and sends them to the Client. By default, when the Dell device relays an EAP-Request frame from
the RADIUS server to the Client, it expects to receive a response from the Client within 30 seconds.
If the Client does not respond within the allotted time, the device retransmits the EAP-Request
frame to the Client. Also by default, the Dell device retransmits the EAP-request frame twice. If no
EAP-response frame is received from the Client after two EAP-request frame retransmissions, the
device restarts the authentication process with the Client.
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, when the Dell device relays an EAP-Request frame from the RADIUS server to the Client,
it expects to receive a response from the Client within 30 seconds. You can optionally specify the
wait interval using the supptimeout command.
For example, to configure the device to retransmit an EAP-Request frame if the Client does not
respond within 45 seconds, enter the following command.
PowerConnect(config-dot1x)# supptimeout 45
