Configuring 802.1X Port Authentication
– 360 –
The operation of 802.1X on the switch requires the following:
The switch must have an IP address assigned.
RADIUS authentication must be enabled on the switch and the IP address of
the RADIUS server specified.
802.1X must be enabled globally for the switch.
Each switch port that will be used must be set to dot1X “Auto” mode.
Each client that needs to be authenticated must have dot1X client software
installed and properly configured.
The RADIUS server and 802.1X client support EAP. (The switch only supports
EAPOL in order to pass the EAP packets from the server to the client.)
The RADIUS server and client also have to support the same EAP authentication
type – MD5, PEAP, TLS, or TTLS. (Native support for these encryption methods is
provided in Windows 7, 8 and10.)
Configuring 802.1X
Global Settings
Use the Security > Port Authentication (Configure Global) page to configure IEEE
802.1X port authentication. The 802.1X protocol must be enabled globally for the
switch system before port settings are active.
Parameters
These parameters are displayed:
System Authentication Control – Sets the global setting for 802.1X.
(Default: Disabled)
EAPOL Pass Through – Passes EAPOL frames through to all ports in STP
forwarding state when dot1x is globally disabled. (Default: Disabled)
When this device is functioning as intermediate node in the network and does
not need to perform dot1x authentication, EAPOL Pass Through can be
enabled to allow the switch to forward EAPOL frames from other switches on to
the authentication servers, thereby allowing the authentication process to still
be carried out by switches located on the edge of the network.
When this device is functioning as an edge switch but does not require any
attached clients to be authenticated, EAPOL Pass Through can be disabled to
discard unnecessary EAPOL traffic.
Default – Sets all configurable 802.1X global and port settings to their default
values.
