Chapter 14 Configuring AAA Servers and the Local Database
Configuring AAA Server Groups
In Timed mode, failed servers are reactivated after 30 seconds of down time.
Note This option is not available for the HTTP Form protocol.
Step 6 If you chose Depletion reactivation mode, add a time interval in the Dead Time field.
The Dead Time is the duration of time, in minutes, to elapse between the disabling of the last server in
a group and the subsequent reenabling of all servers.
Step 7 In the Max Failed Attempts field, add the number of failed attempts permitted.
This option sets the number of failed connection attempts allowed before declaring a nonresponsive
server to be inactive.
Note This option is not available for the HTTP Form protocol.
Step 8 Click OK.
The dialog box closes and the server group is added to the AAA server groups table.
Step 9 In the AAA Server Groups dialog box, click Apply to save the changes.
The changes are saved.
Adding a Server to a Group
To add a AAA server to a group, perform the following steps:
Step 1 From the Configuration > Device Management > Users/AAA > AAA Server Groups > AAA Server
Groups area, click the server group to which you want to add a server.
The row is highlighted in the table.
Step 2 In the Servers in the Selected Group area (lower pane), click Add.
The Add AAA Server Group dialog box appears for the server group.
Step 3 From the Interface Name drop-down menu, choose the interface name where the authentication server
resides.
Step 4 In the Server Name or IP Address field, add either a server name or IP address for the server you are
adding to the group.
Step 5 In the Timeout field, either add a timeout value or keep the default. The timeout is the duration of time,
in seconds, that the security appliance waits for a response from the primary server before sending the
request to the backup server.
Step 6 The other parameters available depend on the server type. See the following sections for parameters
unique to each server type:
• RADIUS Server Fields, page 14-11
• TACACS+ Server Fields, page 14-13
• SDI Server Fields, page 14-13
• Windows NT Domain Server Fields, page 14-13
