3 Make sure that the Web server is running. • Execute the following command to check whether the Web
server is running. If the Web server is running, go to No. 4.
Command:
# ps -auwx | grep httpd
Check procedure:
If
/usr/local/sbin/httpd is displayed in the result of
the
ps command, the Web server is running.
• If the Web server is not running, check the
web-authentication web-port configuration
command.
• If the Web authentication configuration command has been
set correctly, use the
restart web-authentication
web-server command to restart the Web server.
• If the Web server does not start with the above operation,
stop Web authentication by using the
no
web-authentication system-auth-control
command, and wait about 10 seconds. After that, use the
web-authentication system-auth-control
configuration command to restart Web authentication.
4 Check the setting of the authentication IPv4
access list.
• If an unauthenticated terminal sends certain types of
packets to destinations outside the Switch, make sure an
authentication IPv4 access list is set.
When both a standard access list and an authentication
IPv4 access list are set, make sure the filter conditions in
the authentication IPv4 access list are also set in the
standard access list.
• Make sure a filtering condition for discarding IP packets
(such as
deny ip) is not set in the standard access list or
authentication IPv4 access list.
• Make sure addresses including the Web authentication IP
address are not set in the filtering condition in the
authentication IPv4 access list.
• Make sure
any is not set for the destination IP address in
the filtering condition in the authentication IPv4 access list.
• For other cases, go to No. 9.
5Use the
show web-authentication user
command to check whether the user ID is
registered.
• If the user ID is not registered, use the set
web-authentication user command to register the
user ID, password, and VLAN ID.
• For other cases, go to No. 6.
6 Check whether the entered password is correct. • If the password does not match, use the
set
web-authentication passwd command to change the
password. Alternatively, you can use the remove
web-authentication user command to delete the user
ID, and then use the
set web-authentication user
command to register the user ID, password, and VLAN ID
again.
• For other cases, go to No. 9.
