Command History
Usage Guidelines Use this command to add a TACACS+ server to a group of TACACS+ servers to be used for AAA
authentication. Use the tacacs-server host command to define a TACACS+ server for use by the storage
router.
During authentication, the servers are accessed in the order in which they are added to the group.
Note Verification of IP addresses in a server group occurs only at runtime. If a TACACS+ server group
contains an IP address that is not defined as a TACACS+ server, the authentication process generates
error messages and the IP address is skipped. This could cause unexpected authentication failures.
In a cluster environment, AAA management functions are handled by a single storage router. To
determine which storage router is performing AAA management functions, issue the show cluster
command. If you issue the aaa group server tacacs+ server command from a storage router that is not
performing AAA management functions, the CLI displays an informational message with the name of
the node that is currently handling those functions.
name The name of the group of TACACS+ servers. Enter a maximum of 31
characters.
ip-address The IP address of the TACACS+ server.
auth-port port-number (Optional) The server port number. Valid port numbers range from 1 to
65535. If unspecified, the port number defaults to 49.
