802.1X Protocol - Avaya G250 Administration

You can use the following commands to change the RADIUS parameters. These commands are
optional.
Use the set radius authentication retry-number command to set the number
●
of times to resend an access request when there is no response.
Use the set radius authentication retry-time command to set the time to wait
●
before resending an access request.
Use the set radius authentication udp-port command to set the RFC 2138
●
approved UDP port number. Normally, the UDP port number should be set to its default
value of 1812. Some early implementations of the RADIUS server used port number 1645.
To disable RADIUS authentication on the G250/G350, use the set radius
authentication disable command.
To display the RADIUS parameters, use the show radius authentication command.
Shared secrets are not displayed.

G350 RADIUS Configuration Overview.

802.1x protocol

The 802.1x protocol is a method for performing authentication to obtain access to the G250/
G350's LAN ports. 802.1x provides a means of authenticating and authorizing users attached to
a LAN port and of preventing access to that port in cases where the authentication process fails.
On the G350, you can enable 802.1x on the MM314 media module's 10/100 Ethernet ports. On
the G250, you can enable 802.1x on the eight Ethernet LAN PoE ports located on the G250's
front panel.
Note:
You cannot enable 802.1x on the MM314 media module's Gigabit Ethernet port
Note:
(port 51).
The 802.1x protocol defines an interaction between the following three entities:
Supplicant — an entity (the host) at one end of a point-to-point LAN segment that is
●
requesting authentication
Authenticator — an entity (in this case the G250/G350) at the other end of a point-to-point
●
LAN segment that facilitates authentication of the Supplicant
Authentication (RADIUS) Server — an entity that provides an authentication service to the
●
Authenticator. The Authentication Server determines, from the credentials provided by the
Supplicant, whether the Supplicant is authorized to access the services provided by the
Authenticator.
