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
thatspecifiesthenameofthepolicyprofileand/ormanagementleveltheusershouldbeassigned
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
configuredontheswitch,theswitchthendynamicallyappliesthepolicyprofiletothephysical

Filter-ID Attribute Formats
Enterasys NetworkssupportstwoFilter‐IDformats—“decorated”and“undecorated.”The
decoratedformathasthreeforms:
•Tospecifythepolicyprofiletoassigntotheauthenticatinguser(networkaccess
authentication):
Enterasys:version=1:policy=string
wherestringspecifiesthepolicyprofilename.Policyprofilenamesarecase‐sensitive.
•Tospecifyamanagementlevel(managementaccessauthentication):
Enterasys:version=1:mgmt=level
where
levelindicatesthemanagementlevel,eitherro,rw,orsu.
•Tospecifybothmanagementlevelandpolicyprofile:
Enterasys:version=1:mgmt=level:policy=string
