3. Troubleshooting Functional Failures in Operation
94
For the configuration relating to the Web authentication, check the following:
11 Execute the show web-authentication
logging command to check to see if the system
operates correctly.
• If the log "The login failed because of hardware restriction." is
output by the show web-authentication logging
command, see "4.2.2 Action to Be Taken When VLAN
Identification Table Resource Shortage Occurs."
• In static VLAN mode, if authentication information of the port to
which the terminal connects is not displayed, check to see if data on
the port for authentication is correctly set by using the configuration
command web-authentication port.
In addition, make sure the status of the authentication port is neither
linkdown nor shutdown.
• Otherwise, go to No.13.
12 If no account is recorded in the accounting server, use
the show web-authentication
statistics command to check the
communication status with the accounting server.
• If the value of "TxError" of "[Account frames]" is "0", check to see
if aaa accounting web-authentication default
start-stop group radius and radius-server host in
the configuration command are set correctly.
• Otherwise, check Web authentication configuration.
13 Check to see if all the terminals are not able to be
authenticated.
• When all the target terminal are unable to be authenticated, restart the
Web server by using the restart web-authentication
web-server command.
• Otherwise, check to see the configuration of the Web authentication
and correct it if necessary.
14 Check to see the operation log by using the show
logging command.
• When you perform the following operations, Web server (httpd) stop
and restart messages might appear as operation logs.
(1) When Web authentication is activated by the
web-authentication system-auth-control
command soon after suspended by the no
web-authentication system-auth-control
command
(2) When the system changeover in IP8800/S6700(BCU), IP8800/
S6600(CSU), or IP8800/S6300(MSU) occurs
(3) When Web server is restarted by using the restart
web-authentication web-server command
