Before You Begin

To ensure that you can contact the RADIUS servers you plan to use for

 

authentication, send the ping command to each one to verify connectivity.

 

ping ip-address

 

You can then set up communication between the WX switch and each

 

RADIUS server group.

 

 

Configuring

An authentication server authenticates each client with access to a switch

RADIUS Servers

port before making available any services offered by the switch or the

 

wireless network. The authentication server can reside either in the local

 

database on the WX switch or on a remote RADIUS server.

 

When a RADIUS server is used for authentication, you must configure

 

RADIUS server parameters. For each RADIUS server, you must, at a

 

minimum, set the server name, the password (key), and the IP address.

 

You can include any or all of the other optional parameters. You can set

 

some parameters globally for the RADIUS servers.

 

For RADIUS servers that do not explicitly set their own dead time and

 

timeout timers and transmission attempts, MSS sets the following values

 

by default:

 

„ Dead time — 0 (zero) minutes (The WX switch does not designate

 

unresponsive RADIUS servers as unavailable.)

 

„ Transmission attempts — 3

 

„ Timeout (WX wait for a server response) — 5 seconds

 

When MSS sends an authentication or authorization request to a RADIUS

 

server, MSS waits for the amount of the RADIUS timeout for the server to

 

respond. If the server does not respond, MSS retransmits the request.

 

MSS sends the request up to the number of retransmits configured. (The

 

retransmit setting specifies the total number of attempts, including the

 

first attempt.) For example, using the default values, MSS sends a request

 

to a server up to three times, waiting 5 seconds between requests.

 

If a server does not respond before the last request attempt times out,

 

MSS holds down further requests to the server, for the duration of the

 

dead time. For example, if you set the dead time to 5 minutes, MSS stops

 

sending requests to the unresponsive server for 5 minutes before

 

reattempting to use the server.
