WiMAX Overview
Worldwide Interoperability for Microwave Access (WiMAX) is a standards-based wireless technology
that offers high-throughput broadband connections over long distances. WiMAX can be used for a
number of applications, including “last mile” broadband connections, fixed and mobile cellular service,
hotspots and cellular backhaul, and high-speed enterprise connectivity for business.
The Cisco Connected Grid Modules for CGR 1000 Series—WiMAX module is based on the
IEEE 802.16e standard for mobile wireless.
Cisco Broadband Wireless Access products for Mobile WiMAX feature advanced antenna systems and
support adaptive beamforming and multiple-input multiple-output (MIMO). They allow for
multi-megabit service delivery, increased coverage, and greater indoor penetration for the following
benefits:
•
•
Subscribers experience high-quality wireless services
Service providers get fewer service calls, faster time-to-market with new services, and improved
cost efficiencies
This open-standards solution is compliant with the Mobile WiMAX specification and the Profile C
Network Reference Model. It includes a full suite of base stations, antenna systems, access service
network gateways, management systems, and customer premises equipment.

Software Overview
For more on the WiMAX technology, see the following:
WiMAX Link QoS
QoS is configured on the base station. The IEEE standard 802.16e provides the ability to define Quality
of Service (QoS) for different data streams. It contains definitions of available parameters and
scheduling types. The responsibility of QoS is split between the base station and the mobile stations. The
base station scheduler is in control of managing the overall QoS of the system. However, the mobile
station uplink scheduler is responsible for QoS management between service flows allocated to that MS.
The base-station scheduler is entirely responsible for the downlink scheduling.
The WIMAX protocol follows the Request for Connection; Grant for Terminal model. In this model, the
mobile station issues bandwidth requests that indicate the pending demand for each connection. The base
station scheduler, using this information, generates an uplink grant (a grant is the time and frequency
allocation for uplink transmission). The mobile station uplink scheduler uses this grant to allocate access
to the uplink for its service flows based on its local knowledge of service flow priorities. The mobile
station uplink scheduler can be configured for different behavior.
WiMAX connections are defined by service flows. Each service flow is described in terms of QoS
parameters and policy of allocations. Service flows contain classification rules which assign packets to
specified connection.
QoS Support
In the Mobile WiMAX MAC layer, QoS is provided through service flows. This is a unidirectional flow
of packets that is provided with a particular set of QoS parameters. Before providing a certain type of
data service, the base station and user-terminal first establish a unidirectional logical link between the
peer MACs called connection. The outbound MAC then associates packets traversing the MAC interface
into a service flow to be delivered over the connection. The QoS parameters associated with the service
flow define the transmission ordering and scheduling on the air interface.
The connection-oriented QoS therefore, can provide accurate control over the air interface. Since the air
interface is usually the bottleneck, the connection-oriented QoS can effectively enable the end-to-end
QoS control. The service flow parameters can be dynamically managed through MAC messages to
accommodate the dynamic service demand. The service flow based QoS mechanism applies to both DL
and UL to provide improved QoS in both directions. Mobile WiMAX supports a wide range of data
services and applications with varied QoS requirements.

Software Overview
QoS Parameters
The following are configurable QoS parameters available on the base station:
•
Traffic priority—This parameter defines the priority assigned to specified service flow. Services
with higher traffic priority should be given lower delay and higher buffering preference. However
this parameter should not take precedence over any other QoS parameters. The specific algorithm
for traffic priorities depends on vendor solution. Available values for this parameter: 0-7 (higher
value indicates higher priority).
The standard only provides recommendation with respect to using the traffic priority, but it is not a
requirement. T standard is also clear that the scheduler behavior is left for vendors’ differentiation
and is out of the standards’ scope.
•
Maximum sustained traffic rate—This parameter defines the peak information rate of specified

Configuring the Module
The module is configured using the system software. This section covers the following topics:
•
•
•
•
•
•

•
Prerequisites
The MTU size of the WiMAX module default is set to 1500 bytes. The WiMAX module is configured
with a default MTU size of 1500 in order to provide for roaming of a WiMAX mobile device in an IP
sub-convergence layer deployment where an access service network gateway (ASN-GW), such as a
Cisco ASR 5000, is used. However, when an MTU size of 1500 bytes is configured on an Ethernet
interface such as in a sub-convergence deployment of a private WiMAX infrastructure that also runs
Distribution Automation as Ethernet Layer 2 traffic (as for a utility company), then it is possible that
OSPFv2 adjacency goes down due to the WiMAX MTU size not matching that of the Ethernet.
Guidelines and Limitations
The following guidelines and limitations apply to configuring the WiMAX module:
•
•
Data connection can be originated only by the module.
Throughput: Due to the shared nature of wireless communications, the experienced throughput
varies depending on the number of active users or congestion in a given network.
•
Any restrictions that are a part of the terms of service from your carrier.

Configuring the Module
•
When a WiMAX module operates in a network with an Airspan base station that has a MAC profile
definition based on non-authentication, some of its base station models might require the privacy
key management (PKM) to be configured on the WiMAX interface. Updating the base station with
the latest firmware generally eliminates the need to change the configuration of the WiMAX
module.
WiMAX Interface Security
The WiMAX module supports the following security methods:
•
•
•
IEEE 802.16—WiMAX interface Privacy Key Management v2 authentication.
EAP-TLS—Extensible Authentication Protocol Transport Layer Security (RFC 5216), 802.1x.
EAP TTLS—Tunneled Transport Layer Security (RFC 3748).
–
MS-CHAPv2—Challenge-Handshake Authentication Protocol Version 2 (RFC 2759).
Note
You must complete WiMAX scanlist configuration before attempting the WIMAX interface
configuration. Without associating the WIMAX interface with a configured WIMAX scanlist, you
cannot issue a security command on the WIMAX interface since the interface needs to be associated with
a WiMAX scanlist first.
To configure security on the WiMAX module, complete the following in this order:
Step 1
Step 2
Associate the WiMAX scanlist to the WiMAX interface. See Step 2–WiMAX Interface Configuration,
Step 3
Step 4
Step 5
Configure the IP address (static or DHCP) for the WiMAX interface. See Step 2–WiMAX Interface
If you want to configure EAP-TLS or EAL-TTLS as your WiMAX authentication method, then you must
Note
The command pkm crypto algorithm aes does not need to be configured since it was included as the
default configuration for the WIMAX interface.

Configuring the Module
EAP-TLS and EAP-TTLS Authentication Methods
To set up a username and password for the Pairwise Key Management (PKM) of a CGR 1000, the
WiMAX module must be installed and running. CGR 1000s that ship with a pre-installed WIMAX
module will have a pre-installed WiMAX configuration.
You can configure your WiMAX interface for one of the following authentication methods:
•
•
No Authentication (Open)
EAP-TLS Authentication
The WiMAX interface uses trustpoints in the following manner. A certificate-based mutual
authentication is mandatory. The WiMAX module needs both of the following for authentication:
–
A server-root-ca CA certificate authority trustpoint containing the CA certificate that signs the
certificate being used on the AAA/RADIUS server.
–
A device trustpoint for the WIMAX module. The modem on the WiMAX module has an
embedded Airspan-signed device certificate that the supplicant can automatically use as the
device trustpoint for authentication. If users do not want to use this certificate, they must import
and specify a device trustpoint using the imported device certificate.
–
–
To configure EAP-TLS to use a user-defined WIMAX device certificate:
Router(config-if)# shutdown
Router(config-if)# pkm version pkm-v2
Router(config-if)# pkm trustpoint device actual_device_trustpoint_label
Router(config-if)# pkm trustpoint server-root-ca actual_ca_trustpoint_label
Router(config-if)# pkm auth-method eap-tls
Router(config-if)# no shutdown
To configure EAP-TLS to use the embedded Airspan certificate as the WIMAX device
certificate:
Router(config-if)# shutdown
Router(config-if)# pkm version pkm-v2
Router(config-if)# pkm trustpoint server-root-ca actual_ca_trustpoint_label
Router(config-if)# pkm auth-method eap-tls
Router(config-if)# no shutdown
If the trustpoint CLI is not issued for device trustpoint, then the system uses the embedded
certificate.
•
EAP-TTLS Authentication
EAP-TTLS authentication is a one-sided authentication using an Airspan certificate. A
certificate-based authentication is only required for the AAA/RADIUS server. Only a server-root-ca
trustpoint configuration is required for the WIMAX interface to authenticate the AAA/RADIUS
server certificate. The client (WIMAX interface) authentication is executed through MSCHAPv2
authentication (configuring the PKM user and password) through an encrypted tunnel.
Router(config-if)# shutdown
Router(config-if)# pkm version pkm-v2
Router(config-if)# pkm trustpoint server-root-ca actual_ca_trustpoint_label
Router(config-if)# pkm username actual_user_name passwordactual_password
Router(config-if)# pkm auth-method eap-ttls

Configuring the Module
Step 1–WiMAX Scan-list Configuration
To create a scan-list, issue the following commands:
Router# configure terminal
Router(config)# wimax scan-list aaa
Router(config-scan-list)# channel index 1 frequency 2350000 bandwidth 10000
Router(config-scan-list)# nap id 00:00:01 priority 1 channel-index 1
Router(config-scan-list)# nsp id 00:00:01 home
•
NAP (Network Access Provider)—The base station. It provides access to the NSPs which provides
network connectivity.
•
•
NSP (Network Service Provider)—Provides network connectivity and access to NAPs.
Maximum number of the number of frequencies: 1
Step 2–WiMAX Interface Configuration
To attach the scan-list to an interface, issue the following commands:
Router# configure terminal
Router(config)# interface wimax interface_name
Router(config-if)# no shutdown <-- THIS SHOULD BE SHUT
Router(config-if)# scan-list aaa
Router(config-if)# ip address dhcp
Router(config-if)# no shutdown
Step 3–Enable Security Parameters
To enable security parameters, follow these steps:
Step 1
Load the certificates onto the bootflash. Create a trustpoint and import the device certificate.
Router# configure terminal
Router(config)# crypto ca trustpoint device_cert_trustpoint
Router(config)# crypto ca import device_cert_trustpoint pkcs12 path password
Step 2
Step 3
Create a trustpoint and import the server root certificate authority (CA) certificate.
Router(config)# crypto ca trustpoint server_root_CA_trustpoint
Router(config)# crypto ca import server_root_CA_trustpoint pkcs12 path password
Configure the authentication method as EAP-TLS:
Router# configure terminal
Router(config)# interface wimax interface
Router(config-if)# pkm trustpoint server_root_ca server_root_CA_trustpoint
Router(config-if)# pkm auth-method eap-tls
Router(config-if)# pkm version pkm-v2
Router(config-if)# pkm trustpoint device device_cert_trustpoint <-- *
Router(config-if)# pkm trustpoint server_root_ca

Converting Hexadecimal ESN to Decimal Notation
If your network provider requests the 11-digit decimal equivalent of your Electronic Serial Number
(ESN), you must retrieve your ESN, then convert it to decimal notation. See also, Retrieving the
To convert the ESN number from hexadecimal notation to decimal notation:
Step 1
Start with the 8-digit HEX ESN # obtained from the label or using CLI, for example 0x603C9854. This
number consists of two parts:
•
0x60—Serial number
Cisco Connected Grid Modules for CGR 1000 Series—WiMAX Installation and Configuration Guide
OL-26236-03
25
Additional References
•
3C9854—Manufacturer’s code
Step 2
Convert manufacturer’s code to decimal as shown:
•
•
•
Hexadecimal 0x60 equals decimal 96.
If the decimal value is two digits only, prepend it with a zero to expand it to three digits.
Manufacturer’s code is thus 096.
Step 3
Step 4
Convert the serial number to decimal, as shown in the example below:
•
•
•
Hexadecimal 0x3C9854 equals decimal 3971156.
If decimal value is less than 8 digits, add enough zeros to make it into an 8 digit number.
Serial number is thus 03971156.
To obtain complete 11-digit decimal ESN notation, combine manufacturer code and serial number:
•
•
•
Manufacturer code: 096
Serial #: 03971156
Decimal ESN: 09603971156
