H3C S3100-52P Ethernet Switch
Chapter 1 AAA & RADIUS & HWTACACS
Configuration
1-46
z
The user name is not in the userid@isp-name format, or the default ISP domain is
not correctly specified on the switch — Use the correct user name format, or set a
default ISP domain on the switch.
z
The user is not configured in the database of the RADIUS server — Check the
database of the RADIUS server, make sure that the configuration information
about the user exists.
z
The user input an incorrect password — Be sure to input the correct password.
z
The switch and the RADIUS server have different shared keys — Compare the
shared keys at the two ends, make sure they are identical.
z
The switch cannot communicate with the RADIUS server (you can determine by
pinging the RADIUS server from the switch) — Take measures to make the switch
communicate with the RADIUS server normally.
Symptom 2
: RADIUS packets cannot be sent to the RADIUS server.
Possible reasons and solutions
:
z
The communication links (physical/link layer) between the switch and the RADIUS
server is disconnected/blocked — Take measures to make the links
connected/unblocked.
z
None or incorrect RADIUS server IP address is set on the switch — Be sure to set
a correct RADIUS server IP address.
z
One or all AAA UDP port settings are incorrect — Be sure to set the same UDP
port numbers as those on the RADIUS server.
Symptom 3
: The user passes the authentication and gets authorized, but the
accounting information cannot be transmitted to the RADIUS server.
Possible reasons and solutions
:
z
The accounting port number is not properly set — Be sure to set a correct port
number for RADIUS accounting.
z
The switch requests that both the authentication/authorization server and the
accounting server use the same device (with the same IP address), but in fact they
are not resident on the same device — Be sure to configure the RADIUS servers
on the switch according to the actual situation.
