216 CHAPTER 11: 802.1X C ONFIGURATIONBy default, the default data unit is byte and the default data packet unit is onepacket.Configuring the LocalRADIUS AuthenticationServerRADIUS service adopts authentication/authorization/accounting servers to manageusers. Local authentication/authorization/accounting service is also used in theseproducts and it is called local RADIUS authentication server function.Perform the following commands in System View to create/delete local RADIUSauthentication server.Table 233 Creating/Deleting the Local RADIUS Authentication ServerBy default, the IP address of the local RADIUS authentication server is 127.0.0.1and the password is 3com.1) When using local RADIUS server function of 3com, remember the number ofthe UDP port used for authentication is 1645 and that for accounting is 1646.2) The password configured by this command must be the same as that of theRADIUS authentication/authorization packet configured by the command keyauthentication in RADIUS Scheme View.Configuring SourceAddress for RADIUSPackets Sent by NASPerform the following configurations in the corresponding view.Table 234 Configuring Source Address for the RADIUS Packets sent by the NASYou can use either command to bind a source address with the NAS.By default, no source address is specified and the source address of a packet is theaddress of the interface to where it is sent.Setting the Timers of theRADIUS ServerSetting the Response Timeout Timer of the RADIUS ServerAfter RADIUS (authentication/authorization or accounting) request packet hasbeen transmitted for a period of time, if NAS has not received the response fromthe RADIUS server, it has to retransmit the request to guarantee RADIUS service forthe user.You can use the following command to set response timeout timer of RADIUSserver.Operation CommandCreate the local RADIUS authenticationserverlocal-server nas-ip ip_address keypasswordDelete the local RADIUS authenticationserverundo local-server nas-ip ip_addressOperation CommandConfigure the source address to be carried in the RADIUSpackets sent by the NAS(RADIUS scheme view).nas-ip ip_addressCancel the configured source address to be carried in theRADIUS packets sent by the NAS(RADIUS scheme view).undo nas-ipConfigure the source address to be carried in the RADIUSpackets sent by the NAS(System view).radius nas-ipip_addressCancel the configured source address to be carried in theRADIUS packets sent by the NAS(System view).undo radius nas-ip
