group tacacs : To have the network access server send accounting information to a TACACS+ security server, use the group tacacs+ method keyword. group radius : To have the network access server send accounting information to a RADIUS security server, use the group radius method keyword. Note Accounting method lists for SLIP follow whatever is configured for PPP on the relevant interface. If no lists are defined and applied to a particular interface (or no PPP settings are configured), the default setting for accounting applies. group group-name : To specify a subset of RADIUS or TACACS+ servers to use as the accounting method, use the aaa accounting command with the group group-name method.
To specify and define the group name and the members of the group, use the aaa group server command. For example, use the aaa group server command to first define the members of group loginrad : aaa group server radius loginrad server 172.16.2.3 server 172.16.2 17 server 172.16.2.32 This command specifies RADIUS servers 172.16.2.3, 172.16.2.17, and 172.16.2.32 as members of the group loginrad . To specify group loginrad as the method of network accounting when no other method list has been defined, enter the following command:
aaa accounting network default start-stop group loginrad Before a group name can be used as the accounting method, communication with the RADIUS or TACACS+ security server must be enabled. AAA Accounting Types Network Accounting Network accounting provides information for all PPP, SLIP, or ARAP sessions, including packet and byte counts. The following example shows the information contained in a RADIUS network accounting record for a PPP user who comes in through an EXEC session:
