RADIUS Filter-ID Attribute and Dynamic Policy Profile Assignment
IfyouconfigureanauthenticationmethodthatrequirescommunicationwithaRADIUSserver,
youcanusetheRADIUSFilter‐IDattributetodynamicallyassignapolicyprofileand/or
managementleveltoauthenticatingusersand/ordevices.
TheRADIUSFilter‐IDattributeissimplyastringthatisformattedintheRADIUSAccess‐
Accept
packetsentbackfromtheRADIUSservertotheswitchduringtheauthenticationprocess.
EachusercanbeconfiguredintheRADIUSserverdatabasewithaRADIUSFilter‐IDattribute

Note: To configure EAP pass-through, which allows client authentication packets to be forwarded
through the switch to an upstream device, 802.1X authentication must be globally disabled with the
set dot1x command.
Note: B3 devices support up to eight authenticated users per port.
