Configuring The Maximum Number Of Radius Request Transmission Attempts; Configuring The Type Of Radius Servers To Be Supported - 3Com 4500 PWR 26-Port Configuration Manual

received from each other by using the shared keys that have been set on them, and can accept and
respond to the messages only when both parties have the same shared key.
Follow these steps to configure shared keys for RADIUS messages:
To do...
Enter system view
Create a RADIUS scheme and
enter its view
Set a shared key for RADIUS
authentication/authorization
messages
Set a shared key for RADIUS
accounting messages
The authentication/authorization shared key and the accounting shared key you set on the switch must
be respectively consistent with the shared key on the authentication/authorization server and the
shared key on the accounting server.

Configuring the Maximum Number of RADIUS Request Transmission Attempts

The communication in RADIUS is unreliable because this protocol uses UDP packets to carry its data.
Therefore, it is necessary for the switch to retransmit a RADIUS request if it gets no response from the
RADIUS server after the response timeout timer expires. If the switch gets no answer after it has tried
the maximum number of times to transmit the request, the switch considers that the request fails.
Follow these steps to configure the maximum transmission attempts of a RADIUS request:
To do...
Enter system view
Create a RADIUS scheme and
enter its view
Set the maximum number of
RADIUS request transmission
attempts

Configuring the Type of RADIUS Servers to be Supported

Follow these steps to configure the type of RADIUS servers to be supported:
Use the command...
system-view
radius scheme
radius-scheme-name
key authentication
string
key accounting string
Use the command...
system-view
radius scheme
radius-scheme-name
retry retry-times
