4

Check to see authentication Ipv4 access list

• For IP8800/S6700, IP8800/S6600, and IP8800/S6300 models, go to

 

 

No.9.

 

 

• If a terminal before authentication sends packets out of the system,

 

 

confirm that authentication IPv4 access list is applied.

 

 

If access list and authentication IPv4 access list both are applied to

 

 

the port for authentication, make sure the filter conditions described

 

 

in IPv4 access list are set in the access list as well.

 

 

• Confirm that filter condition for denying packets (such as deny ip) is

 

 

not set to the access list/authentication IPv4 access list applied to the

 

 

port for authentication.

 

 

• Confirm that the IP address dedicated for Web authentication is not

 

 

set in the filter condition of authentication IPv4 access list.

 

 

• Confirm that "any" is not specified as a destination address in the

 

 

filter conditions of authentication IPv4 access list.

 

 

• Otherwise, go to No.9.

 

 

 

5

Use the show web-authentication user

• If not registered, use the set web-authentication user

 

command to check to see if user ID is registered.

command to register the user ID, password, and VLAN-ID.

 

 

• Otherwise, go to No. 6.

 

 

 

6

Check to see if the entered password is correct.

• If not correct, use the set web-authentication passwd

 

 

command to change the password, or use the remove

 

 

web-authentication user command to delete the user ID

 

 

once, then use the set web-authentication user

 

 

command to register the user ID, password, and VLAN-ID again.

 

 

• Otherwise, go to No. 9.

 

 

 

7

Use the show web-authentication

• If the value of "TxError" of "[RADIUS frames]" is "0", check to see

 

statistics command to check the

if aaa authentication web-authentication

 

communication status with the RADIUS server.

default group radius and radius-server host in the

 

 

configuration command are set correctly.

 

 

• For IP8800/S3600 and IP8800/S2400 models, even though the dead

 

 

interval lets RADIUS server get recovered from no-response state

 

 

and become able to communicate, the system is not able to collate

 

 

with the RADIUS server during a period of time specified by the

 

 

configuration command authentication radius-server

 

 

dead-interval. As a result, authentication error occurs.

 

 

In this case, if the period of time is too long for the system to wait for

 

 

an authentication error response, change the set value of

 

 

configuration command authentication radius-server

 

 

dead-interval or execute the clear

 

 

web-authentication dead-interval-timer command.

 

 

Authentication action against the first RADIUS will be taken again.

 

 

• Otherwise, go to No. 8.
