No.

Troubleshooting Steps and Command

Action

 

 

 

1

Confirm that VLAN with VLAN authentication

Since communication is enabled only with the VLAN on which VLAN

 

(static) set and other VLANs are not provided on the

authentication (static) is set, exclude the port from authentication or set

 

trunk port.

the VLAN with VLAN authentication (static) and other VLANs on

 

 

different ports.

 

 

 

2

Check to see of the authenticated terminal has moved

If the terminal authenticated on this system moves to the

 

to the non-authentication port in the same VLAN.

non-authentication port, communication is disabled unless

 

 

authentication information is released. Execute the clear dot1x

 

 

auth-statecommand to release the authenticated state on the target

 

 

terminal.

 

 

 

3.12.2Communication Failure on Using Web Authentication

Isolate the problem according to the failure analysis method described in "Table 3-50: Failure Analysis Method for Web Authentication."

For checking Web authentication configuration and accounting information, isolate the problem according to the failure analysis method described in "Table 3-51: Checking Web Authentication Configuration" and "Table 3-52: Web Authentication Failure Analysis Method" each.

Table 3-50: Failure Analysis Method for Web Authentication

No.

Troubleshooting Steps and Command

 

 

Action

 

 

 

 

 

1

Check to see if the login screen is displayed on the

• If login and logout screens are not displayed, go to No. 2.

 

terminal.

• If login screen is displayed in the case of local authentication

 

 

method, go to No.3.

 

 

 

 

 

• If login screen is displayed in the case of RADIUS authentication

 

 

method, go to No.7.

 

 

 

 

 

• If operation log message appears, go to No.14.

 

 

 

 

 

 

2

Check to see if login and logout URLs are correct.

• If not correct, use correct URLs.

 

 

 

 

• In static VLAN mode, if login screen and logout screen are unable to

 

 

display, check the following and correct them if necessary:

 

 

- Check to see if IP address dedicated for Web authentication is

 

 

configured by configuration command web-authentication

 

 

ip

address or URL

redirect

is enabled by

configuration

 

 

command web-authentication redirect enable.

 

 

- When URL redirect is enabled in IP8800/S3600 or IP8800/S2400

 

 

models, check to see if IP address dedicated for Web authentication

 

 

is

configured

by

configuration

command

 

 

web-authentication ip address.

 

 

 

- For IP8800/S6700, IP8800/S6600, and IP8800/S6300 models,

 

 

check to see if IP address dedicated for Web authentication is

 

 

configured by configuration command web-authentication

 

 

ip address.

 

 

 

 

 

• Otherwise, go to No. 3.

 

 

 

3

Check to see if Web server is working.

• Execute the following command and confirm that Web server is

 

 

working properly. If Web server is working, go to No.4.

 

 

[Command]

 

 

 

 

 

# ps -auwx grep httpd

 

 

 

 

[Confirmation]

 

 

 

 

 

If /usr/local/sbin/httpd is displayed by entering the ps command, it

 

 

indicates Web server is working properly.

 

 

 

• If Web server is not working properly, check the status by using the

 

 

configuration command web-authentication web-port.
