Configuring the RADIUS Protocol 227
communicate, NAS returns to the primary server. The following commands can be
used to set the primary server to be active manually, so that NAS can communicate
with it immediately after troubleshooting.
When the primary and second servers are both active or block, NAS sends the
packets to the primary server only.
Perform the following configurations in RADIUS server group view.
By default, the state of each server in RADIUS server group is active.
Setting Username Format Transmitted to RADIUS Server
As mentioned before, clients are generally named in userid@isp-name format. The
part following “@” is the ISP domain name. The Switch 7750 will put users into
different ISP domains according to their domain name. However, some earlier
RADIUS servers rejected the username including ISP domain name. In this case,
you have to remove the domain name before sending the username to the
RADIUS server. The following command decides whether the username to be sent
to RADIUS server carries ISP domain name or not.
If a RADIUS server group is configured not to allow usernames including ISP
domain names, the RADIUS server group cannot be simultaneously used in more
than one ISP domain. Otherwise, the RADIUS server will regard two users in
different ISP domains as the same user by mistake, if they have the same
username (excluding their respective domain names.)
By default, the RADIUS server group acknowledges that the username sent to it
includes ISP domain name.
Setting the Unit of Data Flow that Transmitted to RADIUS Server
The following command defines the unit of the data flow sent to RADIUS server.
