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

uponsuccessfulauthentication.During
theauthenticationprocess,whentheRADIUSserver
returnsaRADIUSAccess‐AcceptmessagethatincludesaFilter‐IDmatchingapolicyprofilename
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.
Notes: The D2 supports up to two authenticated users per port.
The D2 cannot simultaneously support Policy and RFC 3580 on the same port. If multiple users are
configured to use a port, and the D2 is then switched from "policy" mode to "tunnel" mode (RFC-
3580 VLAN to port mapping), the total number of users supported to use a port will be reset to one.
RFC-3580 VLAN authorization is not supported by PWA authentication.
