710 RADIUS Commands
User Guidelines
Names may only be set for authentication servers, not for accounting servers.
Names may consist of alphanumeric characters and the underscore, dash and
blanks.Embed the name in double quotes to use a name with blanks.
NOTE: When multiple radius servers are configured with different names, e.g..
ServerName is name1 and address is 1.1.1.1
ServerName is name2 and address is 1.1.1.2
The radius request is always sent to the first ordered name server list, i.e. name1 server
list would be tried before moving on to name2. Even if the p riority value of servers in
name2 is lower (lower value indicates high priority) the re quest would be sent to the
name1 servers. If for name1 list, the configured servers fail to respond, the request
is sent to the second configured name list.
Within the same server list , the first primary server w ould be tried. You can have multiple
secondary servers in the same name list. From the multiple secondary servers, the
one with the lowest priority value would be tried. For a different named server l ist,
the server name would be based on lexicographic order. For e.g.. if name9, name1,
name6 are configured in this order, name1, then name6, then name9 would be tried.
Example
console(config)#radius-server host 44.44.44.44
console(Config-auth-radius)#name NAME
console(Config-auth-radius)#no name
primary
Use the primary command to specify that a configured server should be the
primary server in the group of authentication servers which have the same
server name. Multiple pri mary servers can be configured for each group of
servers which have the same name. When the RADIUS client has to perform
transactions with an authenticating RADIUS server of the specified name, it
uses the primary server that has the specified server name by default. If it fails
to communicate with the primary server for any reason, it uses the backup
servers configured with the same server name. These backup servers are
identified as the “Secondary” type.
