RADIUS Authentication and Accounting
Configuring RADIUS Accounting
Figure 5-7. Example of Configuring for a RADIUS Server with a Non-Default Accounting UDP Port Number
The radius-server command as shown in figure 5-7, above, configures the
switch to use a RADIUS server at IP address 10.33.18.151, with a (non-default)
UDP accounting port of 1750, and a server-specific key of “source0151”.
2. Configure Accounting Types and the Controls for Sending
Reports to the RADIUS Server
Select the Accounting Type(s):
■ Exec: Use exec if you want to collect accounting information on login
sessions on the switch via the console, Telnet, or SSH. (See also
“Accounting” on page 5-2.)
■ System: Use system if you want to collect accounting data when:
• A system boot or reload occurs
• System accounting is turned on or off
Note that there is no time span associated with using the system option.
It simply causes the switch to transmit whatever accounting data it
currently has when one of the above events occurs.
■ Network: Use Network if you want to collect accounting information
on 802.1X port-based-access users connected to the physical ports on
the switch to access the network. (See also “Accounting” on page 2.)
For information on this feature, refer to “Configuring Port-Based
Access Control (802.1X)” on page 8-1.
Determine how you want the switch to send accounting data to a RADIUS
server:
Because the radius-server command
includes an acct-port element with a non-
default 1750, the switch assigns this value to
the accounting port UDP port numbers.
Because auth-port was not included in the
command, the authentication UDP port is set
to the default 1812.
