Dashboard, can be used to deactivate any active sessions.
Running the Setup Wizard
This section explains how to configure the BBSM Hotspot server by using the Setup Wizard. This wizard
prompts you for your server’s basic configuration parameters and then configures the server with these
settings.
It also prompts you to decide if you would like to create a custom web page at this time:
• If you decide to use a custom web page, the Custom Web Page Wizard launches after the Setup
Wizard completes.
• If you decide not to create a custom web page, the first time you run the Setup Wizard, it applies the
FreeAccess web page to all ports. If you run the Setup Wizard again at a later time, it will not change
the port settings.
Note the following configuration and custom web page options that you can use:
• To configure your server using the Address Change Wizard and Switch Discovery Wizard, refer to
Appendix A, “Advanced Wizards.”
• To configure your server manually on a per-port basis or change your configurations after the initial
setup, refer to Configuring Your Server (Hotspot Configuration), page 3-1.
• To change your port settings after the initial setup, refer to Configuring Ports (Port Configuration),
page 3-27.

Step 3
Enter the field data, as described in Table 2-1. This location data is used globally by BBSM Hotspot.
Table 2-1 Enter Server Settings Field Descriptions
Field Description
Location Name Enter a specific property name. Use up to 50 alphanumeric characters,
such as “Joes Coffee Shop” or “2nd Level Conference Rooms.” This
field is required.
Location Description Enter descriptive text for the location, such as the city or address. You
can use any alphanumeric word or phrase to a maximum of
100 characters, such as “San Diego, CA,” or “Guest cubicles in the
northeast annex.” This field is optional.
E-mail Relay Server Address
(IP address or FQDN)
Enter the IP address or the fully qualified domain name (FQDN) for
the e-mail relay server that is used by your Internet service provider
(ISP) to forward non–web-based e-mail, such as Microsoft Outlook or
Eudora mail programs, from public locations. An example FQDN is
www.ispemail.com. The FQDN can contain a maximum of
100 characters.
This field is optional. Use it only if you want to provide your end users
with e-mail support.
Typical e-mail servers block traffic from unknown sources for security
purposes. The BBSM Hotspot server, as with any public location, is
considered an unknown source that requires an e-mail relay server to
forward end-user mail.

Step 5
Enter the IP addresses, as described in Tab le 2-2. The wizard uses this data to determine BBSM Hotspot
external and internal NIC addresses, the router address, and allocation of the network device, static, and
DHCP client address pools. Note that the wizard requests the external and internal network IDs and
subnet masks and then calculates the external and internal IP addresses automatically. Obtain the
network IDs from your ISP. (An internal network of size Class C or smaller is supported.)
Table 2-3 shows the number of IP addresses available to you based on the subnet code number you enter
after the slash. The table shows the subnet codes that you would most likely use.

Running the Setup Wizard
Chapter 2 Setting Up BBSM Hotspot
Table 2-2 Enter External and Internal IP Addresses Field Descriptions
Field Description
External Network ID Enter the external network IP address block assigned by your ISP. The number
after the slash is the subnet code for the number of IP addresses available in the
block.
Default Gateway This IP address is automatically generated based on the external network ID
that you entered. You cannot change the first three sets of numbers in this
address. This IP address is the address of the gateway (router) assigned by the
ISP and used to access the Internet. Here’s what can and cannot be changed in
this field:
• You cannot change the first three sets of numbers in the IP address.
• The fourth set defaults to the number 1. You can change this fourth octet
after the Setup Wizard populates the Default Gateway based on the
External Network ID.
Your router needs to be configured for the internal network to point to the
external NIC of the BBSM Hotspot server. If you are using a private IP address,
you will also need to create a network address translation (NAT) pool for end
users and one-to-one NAT statements for remote access to internal network
devices.
Internal Network ID This is the Network ID for the subnet that end users use to connect to the BBSM
Hotspot network and, through it, the Internet. The internal subnet consists of the
network devices, end-user clients (such as laptops and PDAs), and the BBSM
Hotspot internal NIC. The number after the slash is the subnet code for the
number of IP addresses available in the block.
You can enter your own private network ID, or you can input a public network
ID.
Primary DNS Server Enter the IP address for the primary domain name system (DNS) server
provided by your ISP. Because BBSM Hotspot is not configured as a DNS
server, DNS forwarding is enabled to forward all DNS requests to a remote
DNS server. BBSM Hotspot acts as a DNS forwarder for end-user DNS requests
as well as its own DNS requests. These requests, such as www.cisco.com, are
resolved into IP addresses so the Internet routers can locate the web server with
the content.

• DHCP Client Addresses—These addresses are allocated to the DHCP client address pool. Because
most network devices are configured as DHCP, after the BBSM NIC and the network device
addresses have been allocated, BBSM Hotspot allocates 90 percent of the available end-user
addresses to the DHCP pool. You can modify this address range in the Hotspot Configuration tool
on the Dashboard or by using the Address Change Wizard.
• Static Client Addresses—These addresses are allocated to the statically configured client address
pool. Because static configurations are not common, this range is allocated by BBSM Hotspot to
10 percent of the total remaining pool after the BBSM NIC and the Network Device addresses have
been allocated.

Configuring DNS Forwarding
This section describes how to configure DNS forwarding if you did not configure your server by using
the Setup Wizard. If you used the Setup Wizard, it configured DNS forwarding automatically.
The Domain Name System (DNS) forwarding feature is enabled on BBSM Hotspot to allow DNS
requests to be relayed to a remote DNS server. BBSM Hotspot is not configured as a DNS server; it acts
as a DNS forwarder for its clients and its own DNS requests. These DNS requests, such as
www.cisco.com, are resolved into IP addresses so the Internet routers can locate the web server with the
content.
Note You must obtain the IP address for your DNS servers from your ISP before you can perform the
following procedure. Refer to the BBSM Hotspot Configuration Requirements Checklist.

Feature Considerations
The following sections describe BBSM Hotspot features that may need some background and
explanation. For information on configuring these features, refer to the “Running the Setup Wizard”
section on page 2-2.
Using Web Pages
A web page set is a set of active server page (ASP) files written in Microsoft JScript, JavaScript, and
HTML. They are executed on both the BBSM Hotspot server and the end user’s browser when the end
user starts the browser. BBSM Hotspot ships with a set of default web page sets shown in Table 2-1 0.
You can use these default web pages without making changes.
If you want to create custom web page sets, the simplest way to create a custom web page set is to use
the Custom Web Page Wizard. Refer to the “Using the Custom Web Page Wizard” section on page 3-32.
2-32
Cisco BBSM Hotspot 1.0 User Guide
78-15293-01
Chapter 2 Setting Up BBSM Hotspot
If you want to customize your web page beyond what is offered by the Custom Web Page Wizard, refer
to the Cisco BBSM 5.2 SDK Developer Guide for instructions on manually customizing web page sets.
This guide can also be used to create a custom web page for pocket PCs.
Note SDK software is provided with Cisco’s BBSM software product so customers can create custom web
page sets and web page policies. Although the Cisco BBSM 5.2 SDK Developer Guide was written to be
used with the BBSM software, the appropriate sections of the guide can be used to manually create
custom web page sets for BBSM Hotspot, if you choose not to use BBSM Hotspot’s Custom Web Page
Wizard. The SDK software, however, cannot be used with BBSM Hotspot. Using this software will
corrupt the BBSM Hotspot server.
You add the new custom web page to the list of web pages on the BBSM Hotspot server by using the
Custom Web Pages option in the Hotspot Configuration tool. Refer to the Adding Custom Web Pages to
BBSM Hotspot, page 3-24.
If a web page requires the end user to enter sensitive information, such as credit card information, an
SSL certificate should be used. When using the SSL web pages, you must buy and install an SSL
certificate. For complete details on installing the certificate, refer to Appendix B, “Installing an SSL
Certificate.”
Feature Considerations
Caution Because web page sets whose name ends in “Clear” do not use SSL security to transmit data to the
BBSM Hotspot server, Cisco does not recommend using them in production. Without SSL, the end user’s
browser transmits RADIUS and credit card information to BBSM Hotspot in clear text. BBSM Hotspot
provides these web pages for demonstration and testing situations in which installing a server certificate
is not feasible.

Using RADIUS with BBSM Hotspot
RADIUS is the industry-standard client/server protocol for user authentication, authorization, and
accounting, which enables users to access the Internet. It is designed to enable a RADIUS client to
communicate with a RADIUS server by using secure communication methods. You can implement one
or more RADIUS servers and a distributed network of RADIUS clients to manage security and retrieve
accounting information across various broadband building sites. This strategy benefits you by providing
greater security, a more scalable architecture, the ability to implement an open standards protocol, and
the ability to leverage future RADIUS enhancements.
The BBSM Hotspot system has a built-in RADIUS client that supports RADIUS and is compliant with
RFCs 2865 and 2866, which are the standards for RADIUS and RADIUS authentication.
Note Because this section explains only the BBSM Hotspot implementation and configuration of a RADIUS
server, the customer is expected to be familiar with RADIUS protocols, as documented in RFC 2865 and
RFC 2866, and how to configure their specific RADIUS server. Configuration of RADIUS servers is
outside the scope of this text.
For detailed information on configuring BBSM Hotspot for RADIUS, refer to the “Configuring
RADIUS Billing” section on page 3-19.
2-34
Cisco BBSM Hotspot 1.0 User Guide
78-15293-01
Chapter 2 Setting Up BBSM Hotspot
Although BBSM Hotspot officially supports the Cisco ACS, Microsoft IAS, and Navis RADIUS server
protocols, it is compatible with any RADIUS server that complies with RFCs 2865 and 2866 and allows
configuration of vendor-specific attributes.
BBSM Hotspot stores accounting and activation/deactivation information in the
RADIUS_SessionHistory table in the BBSM Hotspot database. This table provides independent auditing
of end-user sessions. Session data can be viewed in the RADIUS Session History report or by direct SQL
query.
The RADIUS Session History report shows session activation and deactivation entries:
• Session activation entries—When the end user authenticates through the RADIUS authentication
server and gains Internet access
• Session deactivation entries—When the end user’s Internet access is terminated
The report shows Start and Stop accounting requests and whether or not an accounting response was
received. If BBSM Hotspot is configured to send Interim-Update packets, the report displays the first
Interim-Update accounting request made for each session. Subsequent Interim-Update requests are
reported only if an error occurs during the packet transmission.
RADIUS Authentication, Authorization, and Accounting
Feature Considerations
Each time the end user connects to the BBSM Hotspot service, BBSM Hotspot prompts the user for a
username and password. These values are sent in the Access-Request packet to the RADIUS
authentication server. These authentication servers can be configured by administrators by order of rank
using the RADIUS Server web page in Hotspot Configuration. (Servers are ranked in ascending order,
so the primary RADIUS server is rank = 1, secondary server is rank = 2, and so on.) When sending the
Access-Request packets, BBSM Hotspot begins authenticating servers in ascending order by using all
configured RADIUS authentication servers until an Access-Accept packet is received:
• If a server does not respond within the specified time, BBSM Hotspot attempts to contact that server
up to three times before moving to the next highest ranked server.
• If a server responds with an Access-Reject packet, BBSM Hotspot immediately attempts to
authenticate using the next highest ranked server. (A RADIUS user can have a session active on
more than one computer on the BBSM Hotspot network at the same time if this option is
configured.)
When a RADIUS server sends a vendor-specific attribute that contains a bandwidth kbps value, BBSM
Hotspot throttles the bandwidth of the end-user session to the specified kbps value (if bandwidth throttle
is configured on BBSM Hotspot). To use this feature, administrators need to configure their RADIUS
server to send the vendor-specific attribute to transmit the following:
• A vendor ID of 5263
• A vendor type of 1
• The integer value of the bandwidth kbps desired for the user account
RADIUS accounting provides administrators with end-user session information when Internet access is
granted and terminated. This end-user information can then be retrieved from RADIUS accounting
servers, and independent billing can be performed. Administrators can choose flat-rate or per-minute
billing by using the information that BBSM Hotspot sends to the RADIUS accounting server in Start and
Stop Accounting-Request packets. If configured, BBSM Hotspot also sends Interim-Update packets to
the RADIUS accounting server at intervals set by the administrator.
78-15293-01
Cisco BBSM Hotspot 1.0 User Guide
2-35
Feature Considerations
Chapter 2 Setting Up BBSM Hotspot
Administrators can configure multiple RADIUS accounting servers, which provides redundancy in case
the primary RADIUS server is not responding. As with RADIUS authentication servers, each server is
configured with a ranking. BBSM Hotspot attempts to send accounting packets to accounting servers
until an accounting response packet is successfully received. For each server, BBSM Hotspot attempts
to send accounting request packets up to three times if the server fails to respond.
Table 2-11 shows the RADIUS attributes and the packets in which they are sent from the BBSM Hotspot
server to the RADIUS server. Tabl e 2-12 describes these attributes.

User-Selected Bandwidth (UBand) Web Pages
Chapter 2 Setting Up BBSM Hotspot
User-selected bandwidth (UBand) web pages support a user-specified bandwidth. This feature allows the
administrator to define the service offerings and allows the end user to select from the tiered services
offered directly from the Start page, such as the following:
• 64K for $0.15/minute
• 128K for $0.25/minute
• Unlimited for $0.30/minute
When a UBand web page is used, BBSM Hotspot throttles the session bandwidth at the kbps value that
the end user selects. This bandwidth value is transmitted to the RADIUS accounting servers in the Start,
Stop, and Interim-Update Accounting-Request packets and BBSM Hotspot ignores any bandwidth value
that the RADIUS authentication servers return in the Access-Accept packets.
The two BBSM Hotspot-provided sample web pages that implement this feature are RADIUSUBand and
RADIUSUBandClear. These web pages can be used as templates to customize the tiered services that
you want to offer.
Note Note that the administrators must make sure that the RADIUS accounting servers are configured to
accept the bandwidth that BBSM passes in the vendor-specific attribute and to record this attribute value
so the data can be retrieved for billing. The RADIUS provider is responsible for charging the end user
for the selected bandwidth.
When the user disconnects from the session, the Disconnect web page appears and displays the session
summary information: username, session duration (in minutes), and estimated session charge.
Port Hopping
Cisco BBSM Hotspot 1.0 User Guide
2-38
The port hopping feature allows users to move from port to port without interrupting BBSM Hotspot
service. Within a BBSM Hotspot network, users can move between like types of hardware, such as
wireless access points or switch ports. Users cannot hop between wireless access points and wired
switches. Also, mobility across subnets or cells operated by different customers is not allowed.
78-15293-01
Chapter 2 Setting Up BBSM Hotspot
Port hopping is disabled by default and can only be enabled on a per-port basis by an administrator. For
procedures on different ways to configure port hopping, refer to the following sections:
• “Configuring Your Server (Hotspot Configuration)” section on page 3-1
• “Configuring Ports (Port Configuration)” section on page 3-27
When port hopping is enabled, BBSM Hotspot keeps the session active when the user moves to another
port or temporarily disassociates. For example, disassociation might occur when the signal is weak or an
object comes between the wireless access point and the end user, which causes the user to associate
suddenly with a secondary access point that might be configured to another aggregation switch port.
When a user dissociates from the BBSM Hotspot network, BBSM Hotspot searches for the user until one
of the following occurs:
• The user’s MAC address reappears back on the network within the configured port hop delay time
period. The session then continues without interruption.
• The port hop delay time period expires. BBSM Hotspot then deactivates the session, and the user
must reauthenticate to regain Internet access.
Note the following about port hopping:
• Searching for end user—When port hopping is enabled and an end user disappears from the network,
BBSM Hotspot begins searching for the end user. BBSM Hotspot searches all configured network
elements. It first searches the last known network element that the end user was connected to or
associated with. If the user is not found, BBSM Hotspot then searches all other configured network
elements until the end user is found or the port hop delay time period expires.
• Session duration—The reported duration of an active session varies depending on how the session
terminates:
–
Feature Considerations
If the search succeeds, BBSM Hotspot includes the time that it searched for the user in the
session duration.
–
If the search fails to find the user before the port hop delay time period expires, BBSM Hotspot
does not include the search time in the session duration. In this way, the user that terminates a
session by turning off the computer is not charged for the time that BBSM Hotspot spends
searching for the user on other ports.
• Port hopping from a port hop disabled port—Port hopping is enabled on a per-port basis. The end
user is allowed to hop from a port hop enabled port to any port on the same site and continue the
session even if the port hop status of the destination port is disabled. However, the user is not
allowed to hop from a port hop disabled port at all. If this is attempted, BBSM Hotspot deactivates
the session.
• Port policy—As the user hops from port to port, the port policy that BBSM Hotspot associates with
the user session follows the user to each new port:
–
BBSM Hotspot applies the bandwidth limit (in kbps) specified at session activation to the
session as the user moves from port to port.
–
If a user has selected a dynamic bandwidth boost from a BBSM Hotspot web page, when the
user moves to another port, the bandwidth boost settings follow the session to the new port.
• Active Ports report—While the system is searching for a user, the user session remains active and
appears in the Active Ports report as associated with the last used port.

Cisco BBSM Hotspot 1.0 User Guide

Feature Considerations
Private and Public IP Addresses (Multinet)
You can offer end users the choice of using individually assigned private or public DHCP IP addresses:
• Public IP addresses can be accessed by other devices on the Internet.
• Private IP addresses cannot be accessed by other Internet devices.
To explain the difference between private and public IP addresses, we can compare the IP address to a
phone number. A public IP address is equivalent to a full 10-digit telephone number (619-555-1234),
and a private address is equivalent to an office extension number.
The advantage of using one type of IP address over the other depends on the end user’s needs:
• The advantage of using public IP addresses is that some virtual private network (VPN) systems
require their clients to have public IP addresses to operate correctly.
• The advantage of using private IP addresses is many security threats are eliminated, because other
Internet devices cannot access private IP addresses. Because the local network automatically maps
each private IP address to a different public IP address for data going to and from the Internet, a
private IP address is never visible on the Internet. In addition, because private IP addresses are free,
they of course cost less than public IP addresses.
Chapter 2 Setting Up BBSM Hotspot
BBSM Hotspot servers are configured initially as singlenet. If you want to use a multinet configuration,
you must reconfigure the server for multinet. Singlenet and multinet BBSM Hotspot servers are defined
as follows:
• Singlenet—A singlenet BBSM Hotspot server is configured as a single logical subnet and only
supports one logical subnet of IP address.
• Multinet—A multinet BBSM Hotspot server is configured with two distinct logical subnets and
supports both public and private IP addresses.
To change your BBSM Hotspot server to a multinet configuration, you must configure Windows for
multinet. Refer to the “Configuring Windows for Multinet” section on page 2-26.
To configure public or private IP addresses, refer to the “Running the Address Change Wizard” section
on page A-1. To add, change, or delete public-private IP addresses after the initial configuration, refer
to the “Configuring IP Addresses” section on page 3-3.
The per-port default IP type, which can be overridden by web page sets, can only be changed by the
BBSM Hotspot administrator. To add this functionality to your custom web page sets, refer to the
Cisco BBSM 5.2 SDK Developer Guide.
Cisco Switch Clustering
The BBSM Hotspot software supports the Cisco switch clustering technology that allows up to
16 switches (Catalyst 2950, 3500, and 3550 XL switches) to be clustered together and managed using
just one IP address for the entire cluster. It allows the administrator to update the Network Devices page
in the Hotspot Configuration tool, by using only the master switch IP address and a unique SNMP
password for each switch in the cluster.
The switch clustering feature also continues to support cluster configurations in which each
cluster/switch has a unique IP address.
2-40
Note Before running the Setup Wizard, the administrator must enable the switch clustering capability for all
cluster-capable switches. For detailed information, refer to your switch documentation.
