Command History
Usage Guidelines AAA authentication services are used to provide iSCSI authentication for IP hosts requesting access to
storage resources.
• You can use multiple tacacs-server host commands to specify multiple TACACS+ servers. The
software searches for servers in the order in which you specify them.
• If no server-specific timeout or key values are specified, the global values apply to each TACACS+
server.
• If you use spaces in the key, enclose the key in quotation marks.
Use the aaa group server tacacs+ server command to add a TACACS+ server to a server group. If you
delete a TACACS+ server, delete the server from the TACACS+ server using the
no aaa group server tacacs+ server command.
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.
timeout seconds (Optional) The amount of time the storage router should wait for a reply
from a TACACS+ server before timing out. This setting overrides the global
setting of the tacacs-server timeout command. If no timeout value is
specified, the global value is used.
key key-string (Optional) The authentication and encryption key for all TACACS+
communication between the storage router and this TACACS+ server. The
character string must match the key used by the TACACS+ daemon. This
key overrides the global setting of the tacacs-server key command. If no
key string is specified, the global value is used. If spaces are part of the key
string, enclose the string in quotation marks.
