1973obtain the RADIUS service. The NAS uses the RADIUS server response timeouttimer to control the transmission interval.■ A proper value for the RADIUS server response timeout timer can help improvethe system performance. Set the timer based on the network conditions.■ The maximum total number of all types of retransmission attempts multipliedby the RADIUS server response timeout period cannot be greater than 75.Related command: radius scheme, retry.Example # Set the RADIUS server response timeout timer to 5 seconds for RADIUS schemeradius1. system-view[Sysname] radius scheme radius1[Sysname-radius-radius1] timer response-timeout 5user-name-format (RADIUS scheme view)Syntax user-name-format { with-domain | without-domain }View RADIUS scheme viewParameter with-domain: Includes the ISP domain name in the username sent to the RADIUSserver.without-domain: Excludes the ISP domain name from the username sent to theRADIUS server.Description Use the user-name-format command to specify the format of the username tobe sent to a RADIUS server.By default, the ISP domain name is included in the username.Note that:■ A username is generally in the format of userid@isp-name, of which isp-nameis used by the device to determine the ISP domain to which a user belongs.Some earlier RADIUS servers, however, cannot recognize a username includingan ISP domain name. Before sending a username including a domain name tosuch a RADIUS server, the device must remove the domain name. Thiscommand is thus provided for you to decide whether to include a domainname in a username to be sent to a RADIUS server.■ If a RADIUS scheme defines that the username is sent without the ISP domainname, do not apply the RADIUS scheme to more than one ISP domain, thusavoiding the confused situation where the RADIUS server regards two users indifferent ISP domains but with the same userid as one.Related command: radius scheme.
