Setting the maximum number of EAP frame retransmissions
The Dell PowerConnect 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 PowerConnect 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
PowerConnect device receives RADIUS messages from the RADIUS server, encapsulates them as
EAPOL frames, and sends them to the Client. By default, when the Dell PowerConnect 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 PowerConnect
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 PowerConnect 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
Syntax: supptimeout <seconds>
<seconds> is a number from 1 – 4294967295 seconds. The default is 30 seconds.
