Configuring Authentication-Method Lists For Radius - Dell PowerConnect B-RX Configuration Manual

Setting the RADIUS key
The key parameter in the radius-server command is used to encrypt RADIUS packets before they
are sent over the network. The value for the key parameter on the BigIron RX should match the one
configured on the RADIUS server. The key can be from 1 – 32 characters in length and cannot
include any space characters.
Use the command to specify a RADIUS server key.
BigIron RX(config)# radius-server key mirabeau
Syntax: radius-server key [0 | 1] <string>
When you display the configuration of the BigIron RX, the RADIUS key is encrypted.
BigIron RX(config)# radius-server key 1 abc
BigIron RX(config)# write terminal
...
radius-server host 1.2.3.5
radius key 1 $!2d
NOTE
Encryption of the RADIUS keys is done by default. The 0 parameter disables encryption. The 1
parameter is not required; it is provided for backwards compatibility.
Setting the retransmission limit
The retransmit parameter specifies the maximum number of retransmission attempts. When an
authentication request times out, the Brocade software will retransmit the request up to the
maximum number of retransmissions configured. The default retransmit value is 3 retries. The
range of retransmit values is from 1 – 5.
Use the command to set the RADIUS retransmit limit.
BigIron RX(config)# radius-server retransmit 5
Syntax: radius-server retransmit <number>
Setting the timeout parameter
The timeout parameter specifies how many seconds the BigIron RX waits for a response from the
RADIUS server before either retrying the authentication request, or determining that the RADIUS
server is unavailable and moving on to the next authentication method in the
authentication-method list. The timeout can be from 1 – 15 seconds. The default is 3 seconds.
BigIron RX(config)# radius-server timeout 5
Syntax: radius-server timeout <number>

Configuring authentication-method lists for RADIUS

You can use RADIUS to authenticate Telnet/SSH access and access to Privileged EXEC level and
CONFIG levels of the CLI. When configuring RADIUS authentication, you create
authentication-method lists specifically for these access methods, specifying RADIUS as the
primary authentication method.
