Field Description
Index Specifies an integer in the range 1 to 63 that uniquely
identifies the authentication method on the Nortel
SNAS 4050.
Name Specifies a name for the authentication method, as a
mnemonic aid.
The maximum allowable length of the name string is 255
characters, but Nortel recommends a maximum of 32
characters.
Future releases of the Nortel SNAS 4050 software will
allow you to reference this name in a client filter, so
authentication to this server becomes a condition for
access rights for a group.
Display Name Specifies a name for the method, to display in the Login
Service list box on the portal login page, together with the
names of other authentication services available.
IP Address Specifies the IP address of the RADIUS server.
Port Specifies the port number configured for this server to use
on the RADIUS server. The default is 1812.
Secret Specifies a unique shared secret configured on the
RADIUS server that authenticates the Nortel SNAS 4050
to the RADIUS server.
