The sample configuration described in this document shows a remote client that accesses an Internet Service Provider (ISP) network using Point-to-Point Protocol over Asynchronous Transfer Mode (PPPoA).
The remote client wants to access a Layer 2 Tunneling Protocol (L2TP) service using Layer 3 Service Selection Gateway/Service Selection Dashboard (SSG/SSD). The L2TP service is represented in the configuration with a host IP address of 15.15.15.5. Using Dynamic Host Configuration Protocol (DHCP), the Cisco 677 provides an IP address to the PC from an IP address pool of 10.0.0.2 to 10.0.0.254, with a mask of 255.255.255.0. Also, Port Address Translation (PAT) is enabled on the Cisco 677.
There are three tests for this sample configuration:
The SSG-related debugs during different steps of the service logon by the remote client.
The single sign-on SSD 2.5.1 feature.
Enabling the SSD debugging.

You must reset the Cisco 677 to its default configuration before you implement the new configuration. To restore the default configuration use the set nvram erase command; for example:
cbos#set nvram erase Erasing running configuration. You must use "write" for changes to be permanent. cbos#write NVRAM written. cbos#reboot
Enabling the DHCP server feature on the Cisco 677 Cisco Broadband Operating System (CBOS) automatically creates a pool named "pool0" and assigns a subnet of 10.0.0.0 with a mask of 255.255.255.0. By default, the IP address of the Cisco 677 Ethernet interface is assigned the address of 10.0.0.1, and the "pool0" is then able to lease IP addresses between 10.0.0.2 and 10.0.0.254 for the local LAN clients/PC.

There is currently no verification procedure available for this configuration.
This feature applies to an SSD server. When the SSD server cannot find a host object in its cache database for a remote client sending HTTP traffic, it sends an access request to the SSG. If the SSG has a host object, it sends an access accept message to the SSD. The user can then grant access to the services.
If there is no host object on the SSD or SSG, then the user should authenticate on the SSD with normal SSD logon authentication procedures.
Before you configure SSD or SSG, you have to verify the following:
SSD, SSG, and Authentication, Authorization, and Accounting (AAA) are all running, and all network entities can ping one another.
The remote user can ping any host in the default network (SSG, SSD, AAA) before logging on to the SSD server.
The Network Access Provider (NAP), in this case the Cisco 6400 NRP1, can ping the service destination network.
The remote client cannot ping the remote service destination network.
After all the SSG commands are configured, you must verify that the next hop table for the user's services has been successfully downloaded. Issue the show ssg binding command.

Check that all your direction bindings are active on the SSG.

When a client is initiating an HTTP session to the SSD server, the user sees the SSD server logon home page.
Note: Remember to start the SSD server operation by issuing the UNIX shell command root@crazyball[/export/home/ssd251/ssd]startSSD.sh.
Configure the parameter (REAUTHENTICATE=off) in the dashboard.conf file. The default value is REAUTHENTICATE=on.
Log on to any Web page on the SSD. For example, while you are logged on to the cairo.com service home page, close your browser, and then open it again with http://10.200.56.40:8080.
The host object on the SSD is still in the cache, so you should be able to log on again to the SSD service page that you were logged onto previously. The default behavior is to re-authenticate on the SSD; that is, you have to get to the SSD logon home page.
Type https://10.200.56.40:8443/log in the address bar of the browser.
Click Set Option. All the debugs you selected run, and the output is logged in a log file. The format for the log file name is yy_mm_dd.request.log.
Navigate to the directory on the SSD server where the log files reside.
Using a UNIX editor, open the file /export/home/ssd251/ssd/logs]vi yy_mm_dd.request.log to view the debug output.

At this point the user hasn't logged on to any service. The client first sees MiddleEast, Cairo, then Egyptian Capital in the service list on the SSD Web page. After the client clicks Egyptian Capital, the username and password fields appear on the page. No active service has been associated to the client yet. The username and password that the client provides to gain access to cairo.com service must match those that are configured by the L2TP Network Server (LNS). In this setup, LNS is authenticating the users locally. The username is ayman@cairo.com, and the password is ayman.
