Figure 7-1 Change of password of login user by router administrator

7.2.3.2 Password of router administrator

During operation, default-restart and set the password again when all login users

who have the authority of a router administrator have forgotten their router

administrator passwords and cannot enter the router administrator mode (see

Section 2.2, “Starting the router” for the operation of the default restart.)

7.2.4 Login cannot be authenticated using RADIUS

Confirm the following when login cannot be authenticated using RADIUS.

1. Communication with RADIUS server

Confirm by using a ping command whether the router can communicate with the

RADIUS server. See Subsection 7.5.1, “Communication cannot be done or

communication is disconnected”, when the router cannot communicate. Confirm

that the route for the local address of the router exists in the RADIUS server

when a local address is defined by using configuration definition information.

2. Setting of time-out value and retry count

The time required for judging that the router cannot communicate with the

RADIUS server by the setting of a configuration definition command (CLI type 1)

(radius) is <Set time-out value (second)> x <Set retry count> x <Number of set

RADIUS servers> (maximum). The application (telnet, etc.) of a remote operation

terminal may be terminated due to time-out when this time increases

significantly. In this case, change the setting of the RADIUS configuration

definition information or the time-out setting of the application used in the

remote operation terminal. Time-out is also judged to occur in the application of

the remote operation terminal before the connection to a RADIUS server in

operation, among multiple RADIUS servers specified using configuration

definition information, and is established when telnet or ftp fails in spite of the

fact that a message indicating the success in RADIUS authentication is output to

the operation log. Set the RADIUS server therefore in operation preferentially or

decrease the <Time-out value (second)> x <Number of retry times> value.
