About Users Specifying a RADIUS Server at Login
By default, an MDS switch forwards an authentication request to the first server in the RADIUS server
group. You can configure the switch to allow the user to specify which RADIUS server to send the
authenticate request by enabling the directed request option. If you enable this option, the user can log
in as username@hostname, where the hostname is the name of a configured RADIUS server.
Allowing Users to Specify a RADIUS Server at Login
To allow users logging into an MDS switch to select a RADIUS server for authentication, follow these
steps:
Command
Step 1
switch# config t
Step 2
switch(config)# radius-server
directed-request
switch(config)# no radius-server
directed-request
You can use the show tacacs-server directed-request command to display the RADIUS directed
request configuration.
switch# show radius-server directed-request
disabled
About Vendor-Specific Attributes
The Internet Engineering Task Force (IETF) draft standard specifies a method for communicating
vendor-specific attributes (VSAs) between the network access server and the RADIUS server. The IETF
uses attribute 26. VSAs allow vendors to support their own extended attributes that are not suitable for
general use. The Cisco RADIUS implementation supports one vendor-specific option using the format
recommended in the specification. The Cisco vendor ID is 9, and the supported option is vendor type 1,
which is named cisco-avpair. The value is a string with the following format:
protocol : attribute separator value *
