Installing the WiMAX Module
The Cisco Connected Grid WiMAX module can be installed into any slot of the CGR 1240; however, slot 6 is recommended due to the ease of installing the available cable.
Note Some WiMAX modules are installed into the host router at the factory.
To install the module into an available slot in the Cisco Connected Grid 1120 Router or the Cisco Connected Grid 1240 Router:
Note The Cisco Connected Grid WiMAX module can be hot swapped because online insertion removal (OIR) is allowed—it is not necessary to power down the router:
- When a new WiMAX module is replacing an identical WiMAX module (for example, replacing a failed module), only a power down of the slot is required.
- When a new WiMAX module is replacing a different WiMAX module, power cycling of the router is required for the new WIMAX module to be properly recognized.
Step 1 Before you install (or remove) the Connected Grid WiMAX module from the host router, read the instructions about installing and removing modules in the hardware installation guide of your router. For more information, see the Cisco 1120 Connected Grid Router Hardware Installation Guide or Cisco 1240 Connected Grid Router Hardware Installation Guide.
Step 2 Insert the WiMAX module in the slot.
Step 3 Using a screwdriver, secure the two captive screws.
Removing the WiMAX Module
To remove the Cisco Connected Grid WiMAX module from a slot in the Cisco Connected Grid 1120 Router or the Cisco Connected Grid 1240 Router:

Information about WiMAX
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 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 with 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.
For more information on WiMAX technology, see:
http://www.cisco.com/web/about/ac123/ac147/archived_issues/ipj_11-2/112_wimax.html
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 that 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. Because 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.
QoS Output
The command output shows a sample QoS configuration on a base station. Table 14 and Table 15 show the related show commands.
Note The Cisco CG-OS operating system uses the wimax keyword to refer to the WiMAX interface. The Cisco IOS operating system uses the dot16Radio keyword to refer to the WiMAX interface.
QoS Parameters
The configurable QoS parameters available on the base station are:
- Traffic priority —This parameter defines the priority assigned to the 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 the vendor solution. The values for this parameter are: 0-7 (higher value indicates higher priority).
The standard only provides a recommendation with respect to using the traffic priority, but it is not a requirement. The 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 service flow. If the rate is undefined or is equal to 0, then the rate is limited by physical capacity and other connections. This parameter depends on the vendor solution. The value is expressed as a rate in bits per second (the value does not include overhead caused by MAC headers and CRCs).
- Maximum traffic burst —This parameter defines the maximum burst size that is accommodated for the specified service flow. The value is expressed as a size in bytes.
- Minimum reserved traffic rate —This parameter defines the minimum rate reserved for the specified service flow—the guaranteed rate. The specified rate shall be honored only when sufficient data is available for scheduling. The value is expressed in bits per second (the value does not include overhead caused by MAC headers and CRCs).
- Request/transmission policy —This parameter defines the specific policy for the selected service flow. This policy defines the “shall/shall not” parameters for the following policies:
– Broadcast bandwidth request opportunities
– Multicast bandwidth request opportunities
– Use piggyback requests with data
– Suppress payload headers (CS parameter)
– Pack multiple service data units (SDUs) into single Media Access Control (MAC) Packet Data Unit (PDU)
- Tolerated jitter —This parameter defines the maximum delay variation for the specified service flow. The value is expressed as jitter in milliseconds (ms).
- Maximum latency —This parameter defines the maximum delay between the reception of a packet on the network interface and the forwarding of the packet to the RF interface. The value is expressed as a delay in milliseconds (ms).
- Unsolicited grant interval —This parameter defines the nominal interval between successive data grant opportunities for the specified service flow. The value is expressed as an interval in milliseconds (ms).
- Unsolicited polling interval —This parameter defines the maximal nominal interval between successive polling grants opportunities for the specified service flow. The value is expressed as an interval in milliseconds (ms).
- ARQ enable —This parameter defines whether ARQ (automatic repeat request) will be used for the specified service flow or not. This functionality is optional and depends on the vendor solution. The available values are: 0—disabled, 1—enabled.
WiMAX Interface Security
The Cisco Connected Grid WiMAX module supports the following security methods:
- IEEE 802.16—WiMAX interface Privacy Key Management v2 (PKMv2) 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)
WiMAX X.509 Certificates
To learn more about WiMAX Forum X.509 certificates, see http://www.wimaxforum.org .
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:
The WiMAX interface uses trustpoints in a manner where certificate-based mutual authentication is mandatory. The WiMAX module needs both of the following for authentication:
– A server-root-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:
To configure EAP-TLS to use the embedded Airspan certificate as the WiMAX device certificate:
If the trustpoint CLI is not issued for the device trustpoint, then the system uses the embedded certificate.
EAP-TTLS authentication is one-sided authentication using an Airspan certificate. 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.
Configuring the WiMAX Module
Note The Cisco Connected Grid WiMAX module can operate on CGR 1000 Series routers running the Cisco CG-OS or Cisco IOS operating systems. The CLI commands and their syntax can vary between Cisco CG-OS and Cisco IOS operating systems.
The module is configured using the system software. This section covers the following topics:
- Prerequisites
- Guidelines and Limitations
- Configuring WiMAX Interface Security
- Enabling a WiMAX Interface
- Additional WiMAX Configuration Commands
- WiMAX show Command Examples
Prerequisites
The default maximum transmission unit (MTU) size of the Cisco Connected Grid WiMAX module default is set to 1500 bytes. This default 1500 byte MTU setting provides roaming for WiMAX mobile devices in access service network gateway (ASN-GW) deployments using an IP sub-convergence layer, such as on Cisco ASR 5000s.
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 interface.
Users need to adjust the MTU size based on their network requirements.
Guidelines and Limitations
The following guidelines and limitations apply to configuring the Cisco Connected Grid 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.
- 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 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.
Configuring WiMAX Interface Security
Note The Cisco Connected Grid WiMAX module can operate on CGR 1000 Series routers running the Cisco CG-OS or Cisco IOS operating systems. The CLI commands and their syntax can vary between Cisco CG-OS and Cisco IOS operating systems.
Note The Cisco CG-OS operating system uses the wimax keyword to refer to the WiMAX interface. The Cisco IOS operating system uses the dot16Radio keyword to refer to the WiMAX interface.
Note You must complete a WiMAX scanlist configuration before configuring the WiMAX interface. The WiMAX interface must be associated with a configured WiMAX scanlist—without this prerequisite, you cannot issue a security command on the WiMAX interface.
To configure security on the WiMAX module:
Step 1 Configure the WiMAX scanlist. See the “Configuring a WiMAX Scan List” section.
Step 2 Associate the WiMAX scanlist with the WiMAX interface. See the “Configuring a WiMAX Interface” section.
Step 3 Configure the IP address (static or DHCP) for the WiMAX interface. See the “Configuring a WiMAX Interface” section.
Step 4 If you want to configure EAP-TLS or EAL-TTLS as your WiMAX authentication method, then you must configure the certificate trustpoints. See the “Enabling Security Parameters” section.
Step 5 Configure EAP TLS or EAP-TTLS. See the “Enabling Security Parameters” section.
Note The command pkm crypto algorithm aes does not need to be configured because it is included in the default configuration for the WiMAX interface.
Configuring a WiMAX Scan List
To create a scan-list, issue the commands in Table 16 :
Note Scan-list related definitions include:
- NAP (Network Access Provider)—The base station. It provides access to the NSPs which provide network connectivity.
- NSP (Network Service Provider)—Provides network connectivity and access to NAPs.
Note A scan-list can have multiple different channel frequencies. The frequencies must be within the supported frequency range of the existing wimax module in the router.
Configuring a WiMAX Interface
To configure the WiMAX interface and attach a scan-list to an interface, issue the commands in Table 17 :
Enabling Security Parameters
To enable security parameters:
Step 1 Load the certificates onto the bootflash. Create a trustpoint and import the device certificate.
Cisco CG-OS CGR 1000 Series Routers:
Step 2 Create a trustpoint and import the server root certificate authority (CA) certificate.
Step 3 Configure the authentication method as EAP-TLS as shown in Table 18 :
Note *—The command, pkm trustpoint device device_cert_trustpoint, is not needed if 1) EAP-TLS is using the embedded Airspan certificate, or 2) if EAP-TTLS is used.
Enabling a WiMAX Interface
Note The Cisco Connected Grid WiMAX module can operate on CGR 1000 Series routers running the Cisco CG-OS or Cisco IOS operating systems. The CLI commands and their syntax can vary between Cisco CG-OS and Cisco IOS operating systems.
Note The Cisco CG-OS operating system uses the wimax keyword to refer to the WiMAX interface. The Cisco IOS operating system uses the dot16Radio keyword to refer to the WiMAX interface.
To enable a WiMAX interface, issue the commands in Table 19 :
Additional Cisco CG-OS WiMAX Configuration Commands

This section provides the background information and resources available for troubleshooting the WiMAX module.
- WiMAX Debug Commands
- Checking Signal Strength
- Retrieving the Electronic Serial Number
- Converting Hexadecimal ESN to Decimal Notation
clear interface wimax
To clear statistics relating to the WiMAX interface (wimax) on a router running Cisco CG-OS, use the clear interface wimax interface name statistics command in user EXEC mode.
debug wimax pm
To access debug information relating to the WiMAX interface (dot16) on a router running Cisco CG-OS, use the debug wimax pm { all | demux | deque | error | event | trace | warning } command in user EXEC mode.
clear counters dot16radio
To clear statistics relating to the WiMAX interface (wimax) on a router running Cisco IOS, use the clear counters dot16Radio interface name command in user EXEC mode.
debug dot16
To access debug information relating to the WiMAX interface (dot16) on a router running Cisco IOS, use the debug dot16 {all | errors | events | fsm | rx-packets | timer | tx-packets} command in user EXEC mode.
Checking Signal Strength
If the Received Signal Strength Indication (RSSI) level is very low (for example, if it is less than -110 dBm), follow these steps:
Step 1 Check each antenna connection. Confirm that the QMA connector is correctly threaded and tightened.
Step 2 If you are using a remote antenna, move the antenna cradle and check if the RSSI has improved.
Step 3 If you are using a wireless service provider, contact the service provider to verify that there is service availability in your area.
Retrieving the Electronic Serial Number
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, Converting Hexadecimal ESN to Decimal Notation.
The ESN number is located directly on the modem label in hexadecimal notation.
Using the CLI to Retrieve the ESN on a Cisco CG-OS Router
To retrieve the ESN on a Cisco CG-OS router, use the show sprom module module number slot_number command in interface configuration mode. The sample output shows the ESN number, JAF1542AFJQ.
Using the CLI to Retrieve the ESN on a Cisco IOS Router
To retrieved the ESN on a Cisco IOS router, use the show diag command in user EXEC mode. The sample output shows the ESN number, JAF1635ARAC.
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 Electronic Serial Number.
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 the CLI, for example 0x603C9854. This number consists of two parts:
Step 2 Convert the manufacturer 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—thus the manufacturer code is thus 096.
Step 3 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—thus the serial number is 03971156.
Step 4 To obtain the complete 11-digit decimal ESN notation, combine the manufacturer code and the serial number:
