Dual SIM

The Dual SIM feature implements auto-switch and failover between two cellular networks on the
C880G ISRs. This feature is enabled by default with SIM slot 0 being the primary slot and slot 1 being the secondary (failover) slot.

The Dual SIM feature provides the following commands:

Command
Syntax
Description

gsm failovertimer

gsm failovertimer <1-7>

Sets the failover timer in minutes.

gsm sim authenticate

gsm sim authenticate <0,7> <pin> slot <0-1>

Verifies the SIM CHV1 code.

gsm sim max-retry

gsm sim max-retry <0-65535>

Specifies the maximum number of failover retries. The default value is 10.

gsm sim primary slot

gsm sim primary slot <0-1>

Modifies the primary slot assignment.

gsm sim profile

gsm sim profile <1-16> slot <0-1>

Configures the SIM profile.


Note the following:

For auto-switch and failover to work, configure the SIM profile for slots 0 and 1 using the gsm sim profile command.

For auto-switch and failover to work, configure the chat script without a specific profile number.

If no SIM profile is configured, profile #1 is used by default.

If no GSM failover timer is configured, the default failover timeout is 2 minutes.

If no GSM SIM primary slot is configured, the default primary SIM is slot 0.

This example shows how to set the SIM switchover timeout period to 3 minutes:

router# configure terminal
router(config-controller)# gsm failovertimer 3
 
   

This example shows how to authenticate using an unencrypted pin:

router(config-controller)# gsm sim authenticate 0 1234 slot 0

This example shows how to set the maximum number of SIM switchover retries to 20:

router(config-controller)# gsm sim max-retry 20

This example shows how to set SIM slot 1 as the primary slot:

router(config-controller)# gsm sim primary slot 1
 
   

This example shows how to configure the SIM card in slot 0 to use profile 10:

Note Obtaining a GPS-fixed location requires a supported GPS antenna to be connected to the DIV/GPS port.



Note Obtaining a GPS-fixed location using the Standalone mode can take up to 12 minutes. This depends on the location and type of antenna used.


SMS

The SMS feature enables the router to send and receive SMS messages. This feature also enables the router to save and store the SMS messages in an FTP server.


Note SMS is enabled by default. However, you need to define the FTP server to store incoming and outgoing SMS messages.


The SMS feature provides the following commands:

Command
Syntax
Description

cellular gsm sms send

Saves SMS messages on an FTP server.


In the syntax of these commands, the value of the unit parameter refers to:

(EHWIC) The router slot, WIC slot, and port separated by slashes (for example, 0/1/0).

(C880G) The number 0.

 
   

Note You can use the call screening command dialer caller number callback to authenticate SMS messages that you can use to establish data connections.


This example shows how to send an SMS message (C881G-U-K9):

router#cellular 0 gsm sms send <phone number> "Test message"
 
   

This example deletes all SMS messages (EHWIC-3G-HSPA-U):

router#cellular 0/1/0 gsm sms delete all
 
   

This example shows how to display a summary of SMS messages (EHWIC-3G-HSPA-U):

router#cellular 0/1/0 gsm sms view summary 
ID   FROM                  YY/MM/DD HR:MN:SC  SIZE  CONTENT
0    4087993680            10/05/04 21:29:55  32    from John ...

4    4087993680            10/05/04 21:57:00  32    from Sam ...
 
   

The following example sets FTP path to the SMS_archive directory on the FTP server at 192.168.1.3 (C881G-U-K9 and EHWIC-3G-HSPA-U):

router(config-controller)# gsm sms archive path 
ftp://username:password@192.168.1.3/SMS_archive
 
   

Remotely Initiated Data Callback Using SMS

This feature remotely brings up the cellular interface by sending SMS messages over GSM networks.


Note In the example below, the phone number of the administrator who wants to remotely bring up the link using SMS is 408-123-4567 on a GSM network (dialer caller 4081234567 callback). Replace this number with your own number. To test this example and bring the cellular link up, send an SMS message from your phone.


This example shows how to configure this feature for EHWIC-3G-HSPA-U:

chat-script wcdma "" "atdt*99#" TIMEOUT 180 "CONNECT"

3G WWAN MIB Persistence

This feature allows you to retain 3G WWAN MIB object values and trap settings across router reloads.

Before configuring 3G WWAN MIB, you should perform some SNMP pre-configuration to avoid getting warning messages. The following is an example of SNMP pre-configuration:

snmp-server community public RO
snmp-server community private RW
snmp-server enable traps c3g
 
   

This example shows the settings that you need to configure this feature for C881G-U-K9:

controller Cellular 0

Installing the C881G-U-K9 ISR

To install the C881G-U-K9 ISR, follow the instructions in Cisco 860 Series, Cisco 880 Series, and Cisco 890 Series Integrated Services Routers Hardware Installation Guide. This guide describes the equipment and the procedures for installing the Cisco 860 series, 880 series, and 890 series ISRs.

However, the instructions for connecting the 3G card in the hardware installation guide do not apply to the C881G-U-K9 ISR because it does not have a slot for adding a 3G card. Instead, a 3G modem is embedded in the router.

Installing the SIM Cards

You can install one or two SIM cards into the C881G-U-K9 ISR. Installing two SIM cards lets you take advantage of the Dual SIM feature, which provides a failover mechanism in case the primary SIM card fails.

Figure 8 shows the SIM car installation steps.

Figure 8 SIM Card Installation

To install the SIM cards, follow these steps:


Step 1 Open the door covering the SIM card slots.

a. Insert the tip of the screw driver into the upper latch and gently disengage it as shown in the figure.

b. Remove the door as shown.

Step 2 To insert a SIM card into the SIM 0 slot, hold the SIM card with the contacts facing up as shown and gently push the card into place until it locks in.

Step 3 To insert a SIM card into the SIM 1 slot, hold the SIM card with the contacts facing down as shown and gently push the card into place until it locks in.

Step 4 Reattach the door.

a. Insert the door's bottom latches as shown.

b. Insert the door's upper latch into place as shown.

Figure 19 and Figure 20 show some antenna options that can be used with C880G ISRs and routers with 3G EHWIC cards.

Figure 19 Antenna Options

Figure 20 Antenna Options


Note Antenna orientation can increase or decrease signal reception due to polarization. Typically, an SP's transmitting antenna on the BTS is a vertically polarized omnidirectional antenna, which means the electromagnetic waves are transmitted from it in a vertical plane. Hence, the receiving antenna needs to be vertically oriented too in order to receive the best signal. As the angle of the antenna orientation is changed from vertical to horizontal, only an angular component of the signal is picked up by the antenna. Therefore, if the antenna orientation is horizontal, the antenna picks up the least signal. The signal is received by the antenna as a result of it bouncing off of reflective surfaces. Hence, depending on where the antenna is placed, it may receive different signal strengths. However, the recommended position is vertical.

Configuring 3G

Configuration Prerequisites

The following are prerequisites for configuring Cisco EHWIC and 880G for
3.7G (HSPA+)/3.5G (HSPA):

You must have service availability on your EHWIC card or C801G ISR from a carrier. In addition, you must have network coverage at your router's location. For a complete list of supported carriers, see the data sheet at:

http://www.cisco.com/go/3g

You must subscribe to a service plan with a wireless service provider.

You must obtain and install a SIM card before configuring the EHWIC cards. For instructions on how to install the SIM card, see Connecting Cisco EHWIC-3G-HSPA-U, EHWIC-3G-HSPA+7, and EHWIC-3G-HSPA+7-A to the Network. In the case of C881G-U-K9, obtain and install one or two SIM cards as described in the "Installing the SIM Cards" section.

You must install the required antennas before you configure the EHWIC cards. For more information, see Table 6.

You must check your LEDs for signal reception as described in Table 2.

You should be familiar with the Cisco IOS software, beginning with Release 15.1(3)T or later. (See the Cisco IOS documentation).

To configure your 3G data profile, you need the following information from your service provider:

Username (if required by your carrier)

Password (if required by your carrier)

Access Point Name (APN)

Restrictions for Configuring 3G

The following restrictions apply to configuring the Cisco 3G EHWIC cards and C880G ISRs:

Data connection—Data connection can be originated only by the 3G EHWIC card or the 3G modem in the C880G ISR.

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.

Latency—Cellular networks have higher latency compared to wired networks. Latency rates depend on the technology and carrier. Latency may be higher because of network congestion.

Carrier restrictions—Any restrictions that are a part of the terms of service from your carrier.

Performance—Multiple PDP contexts are supported only in the EHWIC card. This requires an additional 2 Mb memory.

Overview of UMTS/GSM Data Network

The Global System for Mobile Communications (GSM) is the most widely deployed cellular network in the world. It is based on the specification from European Telecommunications Standards Institute (ETSI).

GSM was primarily designed for voice and was circuit switched but due to the popularity of cellular networks and the great demand for data services, GPRS was introduced as a packet switched data overlay over the GSM radio network.

The radio and network resources of GPRS are accessed only when data actually needs to be transmitted between the GPRS mobile user and the GPRS network.

GPRS introduced several new network nodes into the GSM architecture for packet switching, they form the Mobile Packet Core. The Mobile Packet Core includes the Serving GPRS Support Node (SGSN) and the GPRS Gateway Support Node (GGSN).

The SGSN is the node that in some ways carries out the same function as the Foreign Agent in Mobile IP. It tunnels IP packets towards the GGSN and detunnels packets back from the GGSN. It also carries out mobility managed and billing.

The GGSN is the node which carries out the role in GPRS equivalent to the Home Agent in Mobile IP. The GGSN provides the connectivity to the IP network and the SGSN. It is responsible for IP address assignment and is the default router for the connected User Equipment (UE).

Figure 21 shows a GSM network and the network elements it contains.

Figure 21 GSM Network Overview

The Base Transceiver Station (BTS) and Base Station Controller (BSC) are located at the Cell site and are the common nodes for both voice and data services. They provide the radio or the physical layer connectivity between the mobile user and the mobile network.

As the BSC voice and data traffic get segregated, the voice traffic goes to the Mobile Switching Center (MSC), while the data traffic is sent to the GGSN. From the GGSN, the data packets either go directly to the internet or they can be backhauled to the customer data center for a VPN connection.

UMTS is a 3G wireless system that delivers high-bandwidth data and voice services to mobile users. UMTS evolved from GSM. UMTS has a new air interface based on GSM and an IP core network based on general-packet radio service (GPRS). The nodes in a UMTS network are almost the same as in a GSM/GPRS network.

BTS and BSC have been renamed to Node B and Radio Network Controller (RNC), respectively. UMTS addresses the growing demand of mobile and Internet applications for new capacity in the overcrowded mobile communications sky. The new network increases transmission speed to 2 Mb/s per mobile user and establishes a global roaming standard.

High Speed Packet Access (HSPA) is a collection of two mobile protocols, High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA), that extend and improve the performance of existing CDMA/UMTS protocols.

HSDPA and HSUPA provide increased performance by using improved modulation schemes and by refining the protocols by which 3G modem and base stations communicate. These improvements lead to a better utilization of the existing radio bandwidth provided by CDMA.

HSPA improves the end-user experience by increasing peak data rates of up to 14 Mb/s in the downlink and 5.76 Mb/s in the uplink. It also reduces latency and provides up to five times more system capacity in the downlink and up to twice as much system capacity in the uplink, reducing the production cost per bit compared to original CDMA protocols.

Multiple PDP contexts

The dual primary PDP contexts feature is supported on the EHWIC3.7G (HSPA+)/3.5G (HSPA) cards.

Each PDP context is the separate data link over common 3G data connection. It has its own IP address and its own data and QoS profile. For each PDP context, the new IOS cellular interface is created once the EHWIC is initialized in the system. In addition to that, each cellular interface has a corresponding TTY line. This is similar to HWICs with multiple ports.

The EHWIC3.7G (HSPA+)/3.5G (HSPA) cards have Cellular 0/<ehwic_slot>/0, Cellular 0/<ehwic_slot>/1, IOS interfaces. The last number in the triple numbering scheme is the port number.

The multiple cellular interfaces in these 3G HWIC cards behave independently. Any of them can be used to establish data connection. However, only the first interface (for example, Cellular 0/<ehwic_slot>/0), can be used to exercise the full set of modem AT commands using the Reverse Telnet feature.

The HSPA/HSPA+ cellular modem allows you to configure up to16 profiles. The QoS profile configured for an interface is selected by the ATDT*98*#<profile_number>#..."CONNECT" (HSPA modem) or AT!SCACT=1,<profile_number>..."OK" (HSPA+ modem) command in the chat script corresponding to a cellular interface. You must use a different data profile for each cellular interface.


Note If all the three interfaces are used, you must create three separate chat scripts in the router configuration.


Overview of SNMP MIBs

Simple Management Network Protocol (SNMP) development and use is centered around the MIB. An SNMP MIB is an abstract database, a conceptual specification for information that a management application may read and modify in a certain form.

This does not imply that the information is kept in the managed system in that same form. The SNMP agent translates between the internal data structures and formats of the managed system and the external data structures and formats defined for the MIB.

The SNMP MIB is conceptually a tree structure with conceptual tables. For more informtaion on Cisco 3G MIB, see the "3G Cellular WAN MIB Architecture" section. Relative to this tree structure, the term MIB is used in two senses. In one sense, it is actually a MIB branch, usually containing information for a single aspect of technology, such as a transmission medium or a routing protocol.

A MIB used in this sense is more accurately called a MIB module and is usually defined in a single document. In the other sense, a MIB is a collection of such branches. Such a collection might comprise, for example, all the MIB modules implemented by a given agent or the entire collection of MIB modules defined for SNMP.

A MIB is a tree where the leaves are individual items of data called objects. An object may be, for example, a counter or a protocol status. MIB objects are also sometimes called variables.

MIBs can be classified into three categories:

IF MIBs—Describe interface statistics.

Cisco-Entity-Vendortype-OID-MIB.my—ENTITY-MIBs are used to provide general hardware type for both the EHWIC and the modem. CISCO-ENTITY-VENDORTYPE-OID-MIB assigns OIDs for Cisco components (including the HWICs and the modems). The OIDs are then used as the values of entPhysicalVendorType in the ENTITY-MIB.

Cisco 3G WAN MIBs—cellular or wireless-specific MIBs.

3G Cellular WAN MIB Architecture

This section describes the MIB definition and implementation support for Cisco's cellular 3G WAN products on the customer premises equipment (CPE) end.

The 3G Cellular WAN MIB supports the CDMA and GSM set of cellular standards and includes the following technologies:

GSM—GPRS/EDGE/UMTS/HSPA

CDMA—1xRTT/EVDO RevA/EVDO RevB

The 3G cellular MIB uses indexes from the cellular interface and from the modem. You can obtain the interface index using IF MIBs and the modem index using the ENTITY MIBs.

The 3G MIB definition includes the following major sub-trees:

Common objects

CDMA objects

GSM objects

Traps or notifications

You can use MIB object c3gStandard defined in the c3gWanCommonTable to distinguish between CDMA or GSM and implementing MIB for CDMA or GSM.


Note Cisco 3G MIB supports all SNMP versions including V1, V2, V2C, and V3.


At a high-level architecture, the Cisco 3G WAN MIBs are divided into two groups and have the following structure:

1. ciscoWan3gMIBObjects—This group defines all the MIB objects for Cisco 3G WAN MIBs.

2. ciscoWan3gMIBNotifs—This group defines all the trap events for Cisco 3G WAN MIBs.

ciscoWan3gMIBObjects

The ciscoWan3gMIBObjects group has the following sub-groups:

c3gWanCommonTable—Defines the common MIB objects for both CDMA and GSM.

c3gWanCdma—Defines the MIB objects specific for a CDMA set of standards (3GPP2).

c3gWangsm—Defines the MIB objects specific for a GSM set of standards (3GPP).

c3gWanLbs—Defines the MIB objects specific for GPS.

c3gWanSms—Defines the MIB objects specific for SMS.

c3gWanCdma

Under c3gWanCdma, there are seven sub-groups:

c3gCdmaSessionTable for CDMA session-related objects.

c3gCdmaConnectionTable for CDMA connection-related objects.

c3gCdmaIdentityTable for CDMA user identity-related objects.

c3gCdmaNetworkTable for CDMA network-related objects.

c3gCdmaProfile for CDMA user profile-related objects.

c3gCdmaRadio for CDMA radio-related objects.

c3gCdmaSecurityTable for CDMA security-related objects.

c3gWangsm

Under c3gWANgsm, there are five sub-groups:

c3ggsmIdentityTable for GSM user identity-related objects.

c3ggsmNetworkTable for GSM network-related objects.

c3ggsmPdpProfile for GSM PDP profile-related objects.

c3ggsmRadio for GSM radio-related objects.

c3ggsmSecurityTable for GSM security-related objects.

Note By default, all notifications are disabled. To view notifications, you must enable these notifications.



Note The IF MIBs also have notifications for the cellular interface objects that are used in conjunction with the notification type. When you get a notification, you must check the associated objects.


Table 8 shows various 3G WAN MIB traps and what they mean.

Table 8 3G WAN MIB Traps

3G WAN MIB Traps
Details

c3gModemUpNotif

Modem has successfully been recognized.

c3gModemDownNotif

Crash or power-cycle.

c3gServiceChangedNotif

Service type has changed.

c3gConnectionStatusChangedNotif

Connection status has changed.


Restrictions

For the router that runs the SNMP agent, you must configure appropriate access control (for example, SNMP-server community) using the Cisco IOS CLI for the NMS and agent to work properly.

It is strongly recommended that you configure SNMP V3 with authentication/privacy when implementing SNMP SET operation.

Configuring 3G


Note The procedure to configure 3G on both modular and fixed Cisco ISRs is the same except for slot numbering.
For example, for 3G HWICs, the numbering for slot 0, wic 0, and port 0 would be 0/0/0 for all commands. For a fixed Cisco ISR, it would be only 0.
Please refer to platform-specific documentation for details on slot numbering.


To configure the 3G features, follow these procedures:

Data Account Provisioning

Data Call Setup

(Optional) Voice Initiated Data Callback or Remote Dial-In

Data Account Provisioning


Note To provision your modem, you must have an active wireless account with a service provider and a SIM card installed in your 3G EHWIC.

Configuring DDR Backup

To monitor the primary connection and initiate the backup connection when needed, the router can use one of the following methods:

Backup Interface—The backup interface that stays in standby mode until the primary interface line protocol is detected as down and then is brought up.

Floating Static Route—The route through the backup interface has an administrative distance that is greater than the administrative distance of the primary connection route and therefore would not be in the routing table until the primary interface goes down.

Dialer Watch—The backup feature that integrates dial backup with routing capabilities.

To configure DDR backup, perform the following procedures:

Configuring Interfaces to Use a Backup Interface

Configuring DDR Backup Using Dialer Watch

Configuring DDR Backup Using Floating Static Route

Configuring Interfaces to Use a Backup Interface

To configure one or more interfaces to use a backup interface, perform the following steps.

Router(config-if)# backup interface cellular0/3/0

Specifies the cellular interface as backup.

Step 3 

backup delay enable-delay disable-delay

Example:

Router(config-if)# backup delay enable delay

Specifies delay between the physical interface going down and the backup interface being enabled, and between the physical interface coming back up and the backup being disabled.


Note You cannot configure a backup interface for the cellular interface and any other asynchronous serial interface.


Configuring DDR Backup Using Dialer Watch

To initiate dialer watch, you must configure the interface to perform DDR and backup. Use traditional DDR configuration commands, such as dialer maps, for DDR capabilities. To enable dialer watch on the backup interface and create a dialer list, perform the following steps.

Router(config)# interface cellular 0/1/0

Specifies the cellular interface.

Step 8 

dialer string string
Example:

Router(config)# dialer string gsm

Configuring DDR Backup Using Floating Static Route

To configure a floating static default route on the secondary interface, perform the following steps.


Note Make sure you have ip classless enabled on your router.


SUMMARY STEPS

1. configure terminal

2. ip route network-number network-mask {ip address | interface} [administrative distance] [name name]

DETAILED STEPS

 
Command or Action
Purpose

Step 1 

configure terminal

Example:

Router(config)# ip route 0.0.0.0 Dialer 2 track 234

Establishes a floating static route with the configured administrative distance through the specified interface.

Note A higher administrative distance should be configured for the route through the backup interface so that it is used only when the primary interface is down.

(Optional) Voice Initiated Data Callback or Remote Dial-In

The dial-in feature uses the cellular voice connection request to initiate data call back from an EHWIC.


Note For HWICs that support multiple PDP contexts, callback will be initiated only for the first PDP context, for example, for the interface Cellular 0/x/0.


To configure voice-initiated data callback or remote dial-in on your modem, use the following commands in the privileged EXEC mode.

SUMMARY STEPS

1. dialer caller callback

2. show caller

3. debug cellular messages callback

DETAILED STEPS

 
Command or Action
Purpose

Step 1 

dialer caller number callback

Example:

Router# dialer caller 23456789 callback

Configures caller ID screening for a dialer rotary group interface or to bind an incoming call to a particular dialer profile.

Use the no dialer caller callback command to disable callback.

Note In general, the use of this command performs call screening in non-exact mode. It means that the leading numbers comparison is ignored when one of the configured caller ID or incoming call caller ID number is shorter. The comparison is done only for digits of the shorter number. When you configure the dialer caller callback command on the cellular interface, the exact mode is enforced if no wildcard characters like x are specified in the dialer string. In the exact mode, if the numbers do not match in length or in digits, the callback will fail.

Step 2 

show caller

Example:

Router# show caller

Shows caller ID screening.

Step 3 

debug cellular unit messages callback

Example:

Router# debug cellular 0 messages callback

Enables the driver level debug for callback screening.


Note You can use the dialer caller callback command multiple times to configure multiple call back numbers.

Upgrading the Modem Firmware

The fixed and modular ISRs have a 3G modem from Sierra Wireless. The firmware for the modem is upgradable using Cisco IOS commands. The firmware is packaged in a tar distribution file and can be downloaded from the wireless software download page on Cisco.com. Use the following procedure to upgrade the modem firmware:


Caution Before upgrading the modem to a new firmware version, please check if the new firmware version has been certified by your wireless service provider. Using an uncertified firmware version on the modem may impact the wireless service provider network adversely.


Note You can also remotely download firmware over the air by following the same steps listed below.


Refer to the following website for the latest certified firmware version for your carrier and IOS compatibility:

http://www.cisco.com/en/US/prod/routers/networking_solutions_products_genericcontent0900aecd80601f7e.html


Step 1 Go to the Cisco Wireless WAN software download website at

http://www.cisco.com/cisco/software/navigator.html?mdfid=278875243&i=rp.


Note This website is available to registered Cisco.com users only.


Step 2 From the Wireless Integrated Switches and Routers category, select the appropriate 3G modem firmware package.

Step 3 Download the firmware package to a TFTP/FTP server that is accessible to the router.


Note For a remote download, transfer the firmware package from Cisco.com onto flash using the 3G wireless link. Configure the external dialer to bring the interface and the dialer up again after the download.


Step 4 Use the following archive command to untar the firmware package onto the router flash:

archive tar /xtract source-url destination-url

Step 5 Use the following command to initiate the firmware upgrade process:

microcode reload cellular pa-bay slot gsm modem-provision


Caution Do not disconnect the power or switch the router off during the firmware upgrade process as this may result in permanent modem failure.

Command Reference

This section documents the commands that you can use with Cisco EHWIC and 880G for 3.7G (HSPA+)/3.5G (HSPA).


Note The procedure for configuring 3G on both modular and fixed Cisco ISRs is the same except for slot numbering. For example, for 3G EHWICs, the numbering for slot 0, wic 0, and port 0 is 0/0/0 for all commands. For a fixed Cisco ISR, it is 0. See platform-specific documentation for details on slot numbering.

Usage Guidelines

Check the modem status using the show cellular security command.

Entering the command will result in automatic modem reset if you have entered the correct MEP code. If the code is incorrect, the modem pauses and resends the notification to enter MEP code.


Note For modular routers, you must enter the slot/subslot/port numbers for the command. For fixed routers, you must enter slot/port numbers.


Examples

To verify if the modem MEP is locked, use the show cellular security command. The following output is an example when the modem MEP is locked:

router# show cellular 0 security 
Card Holder Verification (CHV1) = Disabled
SIM Status = MEP locked
SIM User Operation Required = Enter MEP code
Number of Retries remaining = 255
router#

The following example shows the output for this command when you enter a correct MEP PIN:

router# cellular 0 gsm mep unlock 12348765
!!!WARNING: Modem will be MEP unlocked with PIN:12348765(8).
Interface will be shutdown for MEP unlock.
This will terminate any active data connection.Are you sure you want to proceed?[confirm]

Maximum number of times the switchover between the two SIM cards can occur.


Command Modes

Controller configuration (config-controller)

Command History

Release
Modification

15.1(4)M

This command was introduced.


Usage Guidelines

When the primary SIM loses service, the ISR automatically tries to switch over to the secondary SIM.

If you do not set the maximum number of tries, the ISR tries to the switchover for a maximum of 10 times (default).

Setting the number of retries to 0 disables the automatic switchover and keeps the service tied to one SIM (the primary SIM).

Every time a SIM switchover occurs, a counter is incremented until it reaches the maximum number of switchover attempts. Then, service is tied to one SIM (the primary SIM) and automatic SIM switchover is stopped.

To see the number of switchover attempts, use the show cellular 0 security command.

Examples

The following example shows how to set the maximum number of SIM switchover retries to 20:

router(config-controller)# gsm sim max-retry 20

Troubleshooting

This section provides the necessary background information and resources available for troubleshooting the Cisco 3G EHWIC.

Verifying Data Call Setup

To verify the data call setup, perform the following steps:


Step 1 After you create a modem data profile using the cellular profile create command and configuring DDR on the cellular interface, send a ping from the router to a host across the wireless network.

Step 2 If the ping fails, debug the failure using the following debug and show commands:

debug chat

debug dialer

debug ppp negotiation

show cellular all

show controller cellular

show interface cellular

show running-config

show ip route

Step 3 Save the output from these commands and contact your system administrator.


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 the antenna connection. Make sure the TNC 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 Contact your wireless service provider to verify if there is service availability in your area.


Verifying Service Availability

The following is a sample output for the show cellular all command for a scenario where the antenna is disconnected and a modem data profile has not been created. The errors in this case have been highlighted with >>>>>>>.

Modem Troubleshooting Using the Diagnostic Port

The RJ-45 port on the faceplate of the 3G EHWIC provides access to the debug port on the Sierra Wireless modem. By connecting an industry-standard diagnostic tool like Qualcomm CAIT/QXDM or Spirent UDM to this port, you can perform radio-level diagnostics and traffic monitoring on the modem.

Use the following test commands to enable/disable the DM port:

router# test cell-hwic 0/1/0 dm-port local {on | off | speed}

router# test cell-hwic 0/1/0 dm-port remote {on | off}

For example, to enable the DM port, use one of these commands:

router# test cell-hwic 0/1/0 dm-port local on

router# test cell-hwic 0/1/0 dm-port remote on

The cable used to connect the PC/laptop running the diagnostic tool is the standard Cisco router console cable (RJ-45 to DB-9).


Note To enable test commands, you must enter the service internal command in global configuration mode.
