Cisco Fourth-Generation LTE Advanced on the Cisco Catalyst IR1101 Rugged Series Router

Cisco LTE Pluggable Modules operate over Fourth-Generation Long-Term Evolution (4G LTE) cellular networks and Third-Generation (3G) cellular networks.

The IR1101 offers LTE support through the use of Pluggable Modules. You can find a list of the supported Pluggable Modules in the Cisco Catalyst IR1101 Rugged Series Router Hardware Installation Guide.

Cisco LTE Pluggable Module support the following 4G/3G modes:

  • 4G LTE —4G LTE mobile specification provides multi-megabit bandwidth, more efficient radio network, latency reduction, and improved mobility. LTE solutions target new cellular networks. These networks initially support up to 100 Mb/s peak rates in the downlink and up to 50 Mb/s peak rates in the uplink. The throughput of these networks is higher than the existing 3G networks
  • 3G Evolution High-Speed Packet Access (HSPA/HSPA+) —HSPA is a UMTS-based 3G network. It supports High-Speed Downlink Packet Access (HSDPA) and High-Speed Uplink Packet Access (HSUPA) data for improved download and upload speeds. Evolution High-Speed Packet Access (HSPA+) supports Multiple Input/Multiple Output (MIMO) antenna capability.
  • 3G Evolution-Data Optimized (EVDO or DOrA) Mode —EVDO is a 3G telecommunications standard for the wireless transmission of data through radio signals, typically for broadband Internet access. DOrA refers to EVDO Rev-A. EVDO uses multiplexing techniques including Code Division Multiple Access (CDMA), as well as Time Division Multiple Access (TDMA), to maximize both individual users' throughput and the overall system throughput.

It is important to understand the architecture of the IR1101 series and the relationship between Modems, SIMs, Interface and Controller. The following table helps to illustrate these relationships.

Prerequisites for Configuring Cisco 4G LTE Advanced

  • If the signal is not good at the router, use the Cisco offered antenna accessories and extension cables to place the antenna away from router in a better coverage area. Please refer to the RSSI/SNT values as displayed through show cellular 0/1/0 all or the LED of the pluggable modem.

  • You must have 4G LTE network coverage where your router is physically placed. For a complete list of supported carriers.

  • You must subscribe to a service plan with a wireless service provider and obtain a Subscriber Identity Module (SIM) card. Only micro SIM is supported.

  • You must install the SIM card before configuring the 4G LTE or router.

  • The standalone antenna that supports GPS capabilities must be installed for the GPS feature to work.

Restrictions for Configuring Cisco 4G LTE Advanced

  • Currently, cellular networks support only user initiated bearer establishment.

  • 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.

  • Cellular bandwidth is asymmetric with the downlink data rate being greater than the uplink data rate.

  • Cellular networks have higher latency compared to wired networks. Latency rates depend on the technology and carrier. Latency also depends on the signal conditions and can be higher because of network congestion.

  • CDMA-EVDO, CDMA-1xRTT, and GPRS technology modes are not supported.

  • Any restrictions that are part of the terms of service from your carrier.

  • SMS—Only one text message up to 160 characters to one recipient at a time is supported. Larger texts are automatically truncated to the proper size before being sent.

  • It is strongly recommended that you configure SNMP V3 with authentication/privacy.

Features not Supported in 4G LTE Advanced

The following features are not supported on Cisco 4G LTE Advanced on the IR1101, when compared to Classic IOS:

  • TTY support or Line

  • Chat script/dialer string

  • DM log output to USB flash is not supported.

Cisco 4G LTE-Advanced Features

Cisco 4G LTE-Advanced supports the following major features:

  • Global Navigation Satellite System (GNSS) (requires a GNSS compliant antenna) and National Marine Electronics Association (NMEA) streaming.

  • Short Message Service (SMS)

  • 3G/4G Simple Network Management Protocol (SNMP) MIB

  • SIM lock and unlock capabilities

  • Dual SIM (Only SIM slot 0 is functional on the P-LTE-VZ pluggable)

  • Auto SIM

  • NeMo

  • Mobile Network IPv6

  • Public Land Mobile Network (PLMN) selection

  • IPv6

  • Multiple PDN

  • LTE Link Recovery

4G GNSS and NMEA

Active GNSS is supported on the SubMiniature version A (SMA) port. Active GNSS antenna is supported only in the standalone mode. An Active GNSS antenna includes a built-in Low-Noise Amplifier that provides sufficient gain to overcome coaxial cable losses while providing the proper signal level to the GNSS receiver. Active GNSS antennae require power from the GNSS receiver SMA port to operate.

National Marine Electronics Association (NMEA) streams GNSS data either from a 4G LTE through a virtual COM port and a TCP/IP Ethernet connection to any marine device (such as a Windows-based PC) that runs a commercially available GNSS-based application.

The following GNSS and NMEA features are supported on the Cisco 4G LTE-Advanced:

  • GNSS standalone mode (satellite-based GNSS)

  • Cisco IOS-XE CLI display coordinates.

  • External application displays router map location

  • Objects in the CISCO-WAN-3G-MIB supports GNSS and NMEA features

  • The Cisco 4G LTE-Advanced only support NMEA over IP and uses show commands in the platform


Note
Assisted GNSS mode is not supported.

Example: Connecting to a Server Hosting a GPS Application

You can feed the NMEA data to a remote server that hosts the GPS application. The server can be connected to the router either directly using an Ethernet cable or through a LAN or WAN network. If the application supports serial port, run a serial port emulation program to create a virtual serial port over the LAN or WAN connection.


Note
Microsoft Streets & Trips is a licensed software that you can download from the Microsoft website.

To connect a Cisco 4G LTE-Advanced through IP to a PC running Microsoft Streets & Trips, perform the following steps:

  1. Connect the PC to the router using an Ethernet cable.

  2. Ensure that the PC and router can ping.

  3. Launch the serial port redirector on the PC.

  4. Create a virtual serial port that connects to the NMEA port on the router.

  5. Launch Microsoft Streets & Trips on your PC.

  6. Select the GPS Menu.

  7. Click Start Tracking.

  8. If you have acquired a location fix from the show cellular 0/1/0 gps command output on the router, the current location is plotted on the graph, and a reddish brown dotted cursor with a circle around it is seen on the map.


Note
If you have not acquired a location fix, the Microsoft application times out and disconnects.

Dual SIM Card


Note
The P-LTE-VZ pluggable which supports Verizon is a single SIM.
SIM card primary slot is selected when router boots up or when NIM reloads. The default slot is 0. If SIM card is not present in the primary slot, select the alternative slot if SIM card is present.
controller cellular 0/1/0
lte sim primary slot <slot#>

If the active SIM card loses connectivity to the network a failover to the alternative SIM card slot occurs.

By default the failover timer is 3 minutes. The failover timer can be set from 3 to 7 minutes.

controller cellular 0/1/0
lte failovertimer <3-7>

You can also manually switch the SIM slot via the command line interface.

cellular 0/1/0 lte sim activate slot <0-1>

Auto SIM

The Auto SIM feature detects the SIM and loads the corresponding firmware. For example, if an AT&T SIM is detected, the modem loads the AT&T firmware.

When Auto-SIM is enabled, it is said to be in Auto-SIM mode and when disabled, it is known as Manual mode. In Auto-SIM mode, the modem selects the right carrier firmware from the list of firmware's available. When in manual mode, you can select the firmware manually. Modem resets every time you make a config change from Auto-SIM enabled to disabled or vice-versa.

The P-LTE-US and P-LTE-GB pluggable modules on the IR1101 support Auto SIM.


Note
uto SIM is always enabled by default.

Using a SIM Card

Cisco 4G LTE-Advanced needs an active SIM card provided by a service provider. The SIM cards are usually provided in an unlocked state so that it can be used without a Personal Identification Number (PIN). If the SIM is unlocked, it can be inserted into a 4G LTE-Advanced and used without an authorization code.

The SIM can be initially locked with a PIN code (4 to 8 digits s long) defined by the service provider. Contact your service provider for the PIN code.

The SIM-Lock feature allows a SIM to be locked or unlocked with a PIN code so that it is used only in an authorized device. Perform the SIM lock and unlock procedures using the Cisco IOS CLI through a console or Telnet/SSH to the Router.

After the SIM is locked, it cannot initiate a call unless authentication is done using the same PIN. Authentication is done automatically by Cisco IOS through configuration of the PIN. This mandatory configuration for automatic SIM authentication is done using the Cisco IOS CLI as part of the router startup configuration.

After the Cisco IOS configuration is in place, the Router can initiate an LTE connection. The Router uses the configured PIN to authenticate prior to the LTE connection. If the Cisco IOS PIN configuration is missing or if the PIN is incorrect, the SIM authentication will fail and the connection will not be initiated.

If the locked SIM is moved to a different Router or to another device, or if the 4G LTE-Advanced in which the locked SIM resides is moved to a different 4G LTE-Advanced slot in the same Router, the Router configuration should be changed. The configuration is associated with the cellular controller that is specific to an Router 4G LTE-Advanced slot number. This will ensure that the SIM card will not be used in any unauthorized device, or, if there are multiple 4G LTE-Advanced in a single Router, that the appropriate PIN is applied to each 4G LTE-Advanced SIM. An authentication command (with the same PIN used to lock the SIM) must be defined on the new device or on the new cellular controller slot to successfully initiate the LTE connection.

The following procedures are used to configure a SIM:


Caution
It is very important to use the correct PIN after it is configured. The SIM card will be blocked if the wrong PIN is entered three consecutive times on a locked SIM during authentication or when trying to unlock a locked SIM. You can unblock a blocked SIM card using the PUK code. Contact your service provider for the PUK code. Use the cellular <slot> lte sim unblock <PUK code> <new PIN code> command to unblock the SIM.

Changing the PIN

Ensure to enter the correct PIN, the SIM card gets blocked if the wrong PIN is entered three consecutive times.

Procedure

Command or Action Purpose

cellular interface lte sim change-pin current-pin new-pin

Example:


Router# cellular 0/1/0 lte sim lock 1111 1234

Note 
Locks or unlocks the SIM card using a PIN code. pin —A code (4 to 8 digits long) provided by your service provider to lock or unlock the SIM card.
Note 
SIM should be in locked state when the PIN is being changed.

Locking and Unlocking a SIM Card Using a PIN

Perform this task to lock or unlock a SIM card given by your service provider. Make sure you enter the correct PIN, the SIM card gets blocked if the wrong PIN is entered three consecutive times.

Procedure

Command or Action Purpose

cellular unit lte sim {lock | unlock } pin

Example:


Router# cellular 0/1/0 lte sim lock 1111

Configure CHV1 for Unencrypted Level7

To configure an encrypted PIN, the scrambled value of the PIN must be obtained. To get the scrambled Level 7 PIN and to configure the SIM CHV1 code for verification using this encrypted PIN, enter the following commands in the EXEC mode. When obtaining the encrypted PIN for a SIM, a username and password are created by configuring password encryption, defining the username and associated password, copying the resulting scrambled password, and using this scrambled password in the SIM authentication command.


Note
After the scrambled PIN has been obtained and used in SIM authentication, the username created can be deleted from the Cisco IOS configuration. A SIM should be locked for SIM authentication to work

Short Message Service (SMS) Capabilities

Cisco 4G LTE-Advanced support receiving, transmitting, archiving, and deleting of SMS messages. This support includes the ability to view up to 25 received texts, and archive more messages in a custom file location. SMS is supported on multiple carriers. Cisco 4G LTE-Advanced also have the capability to revert from LTE SMS to 3G technology if necessary.

A sending device behind a Cisco 4G LTE-Advanced transmits an SMS text message over the 4G cellular link through cellular towers until it the message reaches the recipient’s router, which then notifies the recipient device, such as a cell phone. The receiving device uses the same process to return a reply to the sending device. The following figure describes the flow from a mobile device to a sending device. For SMS transmission to work, end users must have a text-capable device, and optionally, a text plan. If end users do not have a text plan, standard SMS rates apply to their text transmissions.

Figure 1. SMS Network

Data Account Provisioning

One or more modem data profiles can be created to provision a modem on a 4G LTE SKU. An active wireless account with a service provider with one or more (dual) SIM cards must be installed. The modem data profile is pre-configured on the modem.

The following tasks are used to verify the signal strength and service availability of the modem and to create, modify, and delete modem data profiles:

IP Multimedia Subsystem Profiles

IP Multimedia Subsystem (IMS) profiles establish a session, and are a part of the modem configuration and are stored in the modem's NVRAM. An IMS network is an access-independent and standard-based IP connectivity service that enables different types of multimedia services to end users using common Internet-based protocols.

Configuring Cisco 4G LTE Advanced

For 4G-LTE-Advanced, the numbering on the IR1101 for slot 0, module 0, and port 0 is 0/1/0 for all commands on the base unit. On the Expansion Module, the numbering for slot 0, module 0, and port 0 is 0/3/0 for all commands.

4G modems in the Expansion Module will support the same feature set, including GPS, as supported by the same modem in the Base Module.

Verifying Modem Signal Strength and Service Availability

For the 4G LTE Advanced, the unit argument identifies the router slot, module slot, and port separated by slashes (0/1/0).

Guidelines for Creating, Modifying, or Deleting Modem Data Profiles

Customized profiles (Access Point Name(APN) in mobile networks) can be created and used on Cisco 4G LTE Advanced SKU's. Maximum number of profiles that can be created are 16.

Cisco SKU's shipping with specific carrier provisioning file (Can be found in Carrier label under "show cellular <slot> hardware"), default profiles are already populated and can be deployed readily.

In all other cases where profile configurations are not available, separate profiles should be created with required parameters.

You can create multiple profiles on Cisco 4G LTE Advanced. The following are the default internet profile numbers for the modems:

Modem

Profile Number

WP7607 (Global)

Profile 1

WP7601 (Verizon)

Both Profile 1 and Profile 3

WP7603 (AT&T or other SPs)

Profile 1

Follow these guidelines when you configure a data profile using EXEC mode or Config mode :

  • You do not have to make any profile-related changes if your modem comes with a data profile, for instance, AT&T, Sprint and Verizon.
  • If any profile parameter changes are required for a connection type, the changes will likely be carried out in the default profiles.
  • To configure different profile types and use them for a different connection, you can create separate profiles with different parameters (for instance, APN names). Note that only one profile is active at a given time.
  • Use the show cellular <unit> profile command to view the data profile. An asterisk(*) symbol is displayed against the data profile. Double asterisk(**) symbol is displayed against the attach profile.
  • The data profile is used to set up a data call. If you want to use a different profile, that profile needs to be made the default one. Use the lte sim data-profile number command to change the default profile under controller cellular 0/1/0 .

Creating, Modifying, or Deleting Data Profiles Using EXEC Mode

Customized profiles (Access Point Name(APN) in mobile networks) can be created and used on Cisco 4G LTE Advanced SKU's. Maximum number of profiles that can be created are 16.

Configuring a SIM for Data Calls

Locking and Unlocking a SIM Card Using a PIN Code

Perform this task to lock or unlock a SIM card given by your service provider.

The SIM card gets blocked if the wrong PIN is entered three consecutive times. Make sure you enter the correct PIN the SIM is configured with. If your SIM card gets blocked, contact your service provider for a PUK code. Using the PUK code, you can unblock the SIM card.

For the 4G LTE Advanced, the unit argument identifies the router slot, module slot, and port separated by slashes (0/1/0).

Procedure
Command or Action Purpose

cellular unit lte sim {lock | unlock } pin

Example:

Router# cellular 0/1/0 lte sim lock 1111

Locks or unlocks the SIM card using a PIN code.

  • pin —A code (4 to 8 digits long) provided by your carrier to lock or unlock the SIM card.

Changing the PIN Code

Perform this task to change the PIN code of a SIM.

For the 4G LTE Advanced, the unit argument identifies the router slot, module slot, and port separated by slashes (0/1/0).

Procedure
Command or Action Purpose

Shows the security information of the modem, including the SIM lock status.

Configuring Automatic Authentication for a Locked SIM

An unencrypted PIN can be configured to activate the Card Holder Verification (CHV1) code that authenticates a modem.

The SIM card gets blocked if the wrong PIN is entered three consecutive times. Make sure you enter the correct PIN the SIM is configured with. If your SIM card gets blocked, contact your service provider for a PUK code.

Follow these procedures when using an unencrypted Level 0 PIN to configure CHV1. For instructions on how to configure CHV1 using an encrypted Level 7 PIN, see the Configuring an Encrypted PIN for a SIM.

A SIM should be locked for SIM authentication to work. To verify the SIM’s status, use the show cellular unit security command.

For the 4G LTE Advanced, the unit argument identifies the router slot, module slot, and port separated by slashes (0/1/0).

Procedure
  Command or Action Purpose

Step 3

lte sim authenticate 0 pin

Authenticates the SIM CHV1 code by using an unencrypted (0 ) keyword and PIN. This PIN is sent to the modem for authentication with each subsequent LTE connection. If authentication passes based on the configured PIN, the data call is allowed. If authentication fails, the modem does not initiate the data call.

Note 
This command is valid only when an unencrypted PIN is used. To configure CHV1 code using an encrypted PIN, see the Configuring an Encrypted PIN for a SIM.

Configuring an Encrypted PIN for a SIM

To configure an encrypted PIN, the scrambled value of the PIN must be obtained. To get the scrambled Level 7 PIN and to configure the SIM CHV1 code for verification using this encrypted PIN, enter the following commands in the EXEC mode.


Note
When obtaining the encrypted PIN for a SIM, a username and password are created by configuring password encryption, defining the username and associated password, copying the resulting scrambled password, and using this scrambled password in the SIM authentication command. After the scrambled PIN has been obtained and used in SIM authentication, the username created can be deleted from the Cisco IOS configuration.

Note
A SIM should be locked for SIM authentication to work. To verify the SIM’s status, use the show cellular <unit> security command.

Note
For the 4G LTE SKU, the unit argument identifies the router slot, module slot, and port separated by slashes (0/1/0).

Enabling Modem Crashdump Collection

Modem crashdump collection is useful in debugging firmware crash. To collect crash data, the modem has to be pre-configured so that it will stay in memdump mode after a crash. Memdump mode is a special boot-and-hold mode for the memdump utility to collect crash data.

To enable modem crashdump collection, perform the following steps.


Note
The integrated modem crashdump collection feature is supported only on 3G HSPA and 4G LTE Advanced based SKUs.

Before you begin

The device will need to be in boot-and-hold mode.
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#controller cel 0/1/0
Router(config-controller)#lte modem crash-action ? 
boot-and-hold Remain in crash state

Router(config-controller)#lte modem crash-action boot-and-hold

This ensures that whenever the router crashes, it will stay in that state and will not try to recover. By default the crash-action is reset which means the modem will reset and try to recover itself whenever it crashes. The above boot-and-hold command is used to keep the modem in a crashed state so that you can capture crashdump using the following command: 

Router#test cell-cwan 0/1/0 modem-crashdump ?
off Disable Modem firmware crash dump
on Enable Modem firmware crash dump

Router#test cell-cwan 0/1/0 modem-crashdump on

This will capture the crashdump and store it in flash.

Procedure

Command or Action Purpose

test { cell-cwan } unit modem-crashdump { on location | off }

Example:

Router# test cell-host 0/1/0 modem-crashdump on local_uf

Enables or disables modem crashdump collection.

  • cell-host

    —Keyword for fixed platform.

  • cell-cwan

    — Keyword for LTE on a modular inside platform.

  • unit

    —For LTE module, this is the router slot, module slot, and port separated by slashes (for example, 0/1/0). For fixed platform, this is the number 0.

  • on

    Enables crashdump log collection.

  • location

    —Specifies the destination URL where the modem crashdump logs will be stored.

  • off

    —Disables crashdump log collection.

Displaying Modem Log Error and Dump Information

As part of the 3G serviceability enhancement, commands strings (at!err and at!gcdump ) can be sent to the modem using Cisco IOS CLI rather than setting up a reverse telnet session to the cellular modem to obtain log error and dump information.

To obtain log error and dump information, perform the following steps.


Note
The modem log error and dump collection feature is supported only on 3G SKUs.

Procedure

  Command or Action Purpose
Step 1

show cellular unit log error

Example:


Router# show cellular 0/1/0 log error

Shows modem log error and dump information.
Step 2

test cellular unit modem-error-clear

Example:


Router# test cellular 0/1/0 modem-error-clear

(Optional) Clears out the error and dump registers. By default, error and dump registers are not cleared out after a read. This command changes the operation so that registers are cleared once they are read. As a result, the AT command strings are changed to “at!errclr=–1 ” for CDMA and “at!err=0 ” for GSM modems.

Configuring Cellular Modem Link Recovery

The cellular modem link recovery feature is disabled by default and it is recommended to enable the link recovery feature.


Note
No manual operations or automated scripts interacting with 4G modems may be possible until and unless the modems have come fully in-service. Modems may take approximately 4 minutes after platform bootup and CLI available to be able to allow full interaction and establish IP connectivity. A typical modem power-cycle may also take approximately 4 minutes before any interaction is possible. Modems are in-service after the console displays “%CELLWAN-2-MODEM_RADIO: Cellular0/x/0 Modem radio has been turned on” – where x is the modem slot number.

To enable or disable the cellular modem link recovery feature, if required, perform the following steps:

Procedure

  Command or Action Purpose
Step 1

configure terminal

Example:


Router# configure terminal

Enters global configuration mode.
Step 2

controller cellular unit

Example:


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

Enters cellular controller configuration mode.
Step 3

{lte } modem link-recovery disable | no lte | modem link-recovery disable }

Example:

Router(config-controller)# lte modem link-recovery disable    


Router(config-controller)# no lte modem link-recovery disable


Device#show run | sec controller Cellular 0/1/0
controller Cellular 0/1/0
lte modem link-recovery rssi onset-threshold -110
lte modem link-recovery monitor-timer 20
lte modem link-recovery wait-timer 10
lte modem link-recovery debounce-count 6


Example:
Device#configure terminal
Device(config)#controller Cellular 0/1/0
Device(config-controller)#lte modem link-recovery
 monitor-timer 30
Device(config-controller)#lte modem wait-timer 15
Device(config-controller)#lte modem debounce-count 8
Device(config-controller)#lte modem rssi onset-threshold -100

Enables or disables the cellular modem link recovery feature.

Enables or disables the cellular modem link recovery feature.

Once we enable link-recovery, the default Cisco recommended values for link-recovery parameters are populated.

We can change the values of link-recovery parameters from the default Cisco recommended values, by using cli for each parameter like in example.

Note 
Changing the default recommended cisco values is not advised as it will impact ideal performance of link-recovery feature.
Step 4

end

Example:


Router(config)# end

Exits the configuration mode and returns to the privileged EXEC mode.

Cellular Modem Link Recovery Parameters

There are four configurable parameters to adjust the behavior of cellular link recovery. The default values optimized for the best performance of the feature and changing it is not recommended unless advised by Cisco.

The following table explains the link recovery parameters.:

Table 2. Link Recovery Parameters

Parameter

Description

rssi onset-threshold

This parameter defines the RSSI value below which the link recovery feature triggers additional scrutiny to look for potential issues and take action if needed. The range of this parameter can be set from -90 dBm to -125 dBm. The recommended and default value is -110 dBm.

monitor-timer

This parameter determines how often link recovery looks for potential issues. The default value for this parameter is 20 seconds meaning that link recovery feature will be triggered every 20 seconds and look at certain parameters to determine if there is a potential issue. You can configure the monitor-timer range between 20 to 60 seconds. Increasing the monitor timer value above 20 seconds will increase the response time of the feature.

wait-timer and debounce-count

The wait-timer parameter is used in conjunction with the debounce-count parameter to perform more frequent, additional checks, once the link recovery feature has identified a potential issue that needs to be recovered from, with a modem power-cycle. The default value for wait-timer is 10 seconds and the default value for debounce- count is 6. With this setting, once link recovery has identified an inoperative modem state, it performs additional checks every 10 seconds, up to 6 times, to determine if the issue has been resolved without a modem power-cycle. Reducing the debounce-count and the wait-timer makes faster link recovery, while reducing them may increase the time for recovery. The configurable range for wait-timer is 5-60 seconds. The configurable range for debounce-count is 6-20 seconds.

Verifying the Cellular Modem Link Recovery Configuration

To determine if the cellular modem link recovery is enabled, use the show controller cellularunit command. In this example, the cellular modem link recovery feature related information is highlighted.

When the cellular modem link recovery occurs and modem is power cycled, you can see the %CELLWAN-2-MODEM_DOWN message on the console logs and additionally there is a %CELLWAN-2-LINK_RECOVERY message which indicates that action has been taken by the cellular modem link recovery feature.

Whenever the cellular modem link recovery has occurred, it updates the Modem timeouts counter under the Modem Management Statistics section of the show controller cellular unit command output. Modem parameters at the last timeout section has information that helps to identify the cause of the issue that triggered link recovery

In the following example log, the messages, modem time out counter, and modem parameters at the last time out are highlighted.

Cellular Back-off

Cellular Backoff is a feature introduced in IOS which addresses the concerns about Cisco LTE router not performing backoff in error handling. When PDP Context activation is failing, modems may receive from a cellular service provider. As a result, when some specific error codes (for example: 29, 33) are received by the modem from a cellular network, the router’s IOS incrementally adds interval in sending PDP Context Activation requests and any IP traffic such as not to load service provider network with requests that are known to IOS as failing. Once PDP Context is established and IP traffic is successful, the Cellular Backoff is removed for normal operation.

This back-off implementation will be a generic design and will NOT be specific to a particular service provider. There will be NO IOS CLI command to disable this new feature either.

Example: GRE Tunnel over Cellular Interface Configuration

The following example shows how to configure the static IP address when a GRE tunnel interface is configured with ip address unnumbered cellular interface :


Note
The GRE tunnel configuration is supported only if the service providers provide a public IP address on the LTE interface.

Note
For service providers using a private IP address, the point-to-point static GRE tunnel cannot be set up with a private IP address at one end and a public IP address on the other end.

Example: 4G LTE Advanced as Backup with NAT and IPSec

The following example shows how to configure the 4G LTE Advanced on the router as backup with NAT and IPsec:

The receive and transmit speeds cannot be configured. The actual throughput depends on the cellular network service.

For service providers using a private IP address, use the crypto ipsec transform-set esp command (that is, esp-aes esp-sha256-hmac...).

Upgrading the Modem Firmware

The IR1101 uses Sierra Wireless modems that are supported on Cisco 4G LTE Advanced. The firmware for the modem is upgradable using Cisco IOS commands. The firmware is typically a Crossword Express (cwe) file and can be downloaded from the wireless software download page on Cisco.com. For some modems, such as the EM74XX series, the file type is an *.spk file.

Prior to performing the cellular modem firmware upgrade, make sure of the following:

  • The "microcode reload …" command is issued only from router's base directory.
  • The modem firmware directory must contain the following:
    • Only the *.spk file
    • Only the *.cwe file
    • Only the *.nvu file
    • Only a matching pair of *.cwe and *.nvu files for the exact same version
  • The modem firmware directory MUST NOT contain any other files

Note
Firmware upgrade is supported on utility flash.

Use only Cisco certified firmware. Using a firmware version not certified by Cisco may impact the wireless service provider network adversely.


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

Note
Firmware downgrade is not supported.

Note
Not all IR1101 cellular interfaces can support 2G (only P-LTE-GB), and may not support 3G (P-LTE-VZ).

Details about supported cellular pluggable module SKUs and modems can be found in the IR1101 Hardware Installation Guide here: https://www.cisco.com/c/en/us/td/docs/routers/access/1101/hardware/installation/guide/1101hwinst/pview.html#72641

You can determine which radio bands are supported by using the the following command:
IR1101#show cellu 0/1/0 radio band 

LTE bands supported by modem:
- Bands 1 3 7 8 20 28.
LTE band Preference settings for the active sim(slot 0):

Upgrading the Modem Firmware Manually With CLI

Procedure

  Command or Action Purpose
Step 1

Go to the Cisco Wireless WAN software download website at: http://software.cisco.com/download/navigator.html

Provides access to Cisco Wireless WAN software downloads page to select the firmware for Cisco 4G.

Note 
This website is only available to registered Cisco.com users.
Step 2

On the Cisco Wireless WAN software page, go to Products -> Cisco Interfaces and Modules -> Cisco High-Speed WAN interface Cards and select your product from the list of available cards.

Select your product for firmware upgrade.

Step 3

Select and download the appropriate firmware.

Download the modem firmware file to flash memory on the router.

Step 4

terminal monitor

Example:


Router# terminal monitor

Enables the logging console in privileged EXEC mode.

Step 5

microcode reload cellular pa-bay slot modem-provision [flash :<firmware_directory_name>]

Example:

Router# microcode reload cellular 0 slot modem-provision bootflash:/<firmware directory>

Initiates the firmware upgrade process.

For the IR1101 Base, the firmware upgrade would use microcode reload cellular 0 1 ...

For the IR1101 Expansion Module, the firmware upgrade would use microcode reload cellular 0 3 ...

Note 
Modem firmware upgrade may take 10-15 mins from issuing the microcode reload command to the modem coming up. The router console will display 'FW_UPGRADE: Firmware upgrade success.....' message to indicate the firmware upgrade completed. The modem will reset itself and may take an additional 5 minutes to be up in-service.

  • pa-bay—Use 0 for 4G LTE Advanced.

  • slot—For 4G LTE Advanced, slot number, 0 to 3, where the 4G LTE Advanced is plugged in.

  • For remote download, you can transfer this using the wireless link from Cisco.com onto flash.
Step 6

Troubleshooting

This section provides the essential information and resources available for troubleshooting the Cisco 4G LTE Advanced feature.

Verifying Data Call Setup

To verify the data call setup, follow these steps:

  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.

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

  3. debug chat

  4. debug modem

  5. debug dialer

  6. show cellular all

  7. show controller cell0/1/0

  8. show interface cellular

  9. show running-config

  10. show ip route

  11. show platform

  12. 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:

Procedure

  Command or Action Purpose
Step 1

Ensure at least one antenna is connected to the 'MAIN' RF port on the 4G module. Preferably both MAIN and DIV RF ports should be connected to antenna for better RF signal. Check to ensure the antenna are 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.

Modem Troubleshooting Using Integrated Modem DM Logging

As part of the 3G and 4G serviceability enhancement in Cisco IOS, DM log collection has been integrated into Cisco IOS, eliminating the need for an external PC and simplifying the DM log collection process. The lte modem dm-log command can be used in controller cellular configuration mode to configure integrated DM logging to monitor traffic on the modem. See the Cisco 3G and 4G Serviceability Enhancement User Guide for more information on configuring Integrated DM Logging parameters.

Modem Settings for North America and Carriers Operating on 700 MHz Band

For LTE-EA deployments in North America and for carriers operating in the 700 MHz band, the following changes to the modem settings are required to prevent long network attach times.

The output of show cellular 0/1/0 all command shows the following:

  • Current RSSI is –125 dBM

  • LTE Technology Preference = No preference specified (AUTO)

The following sections explain useful commands for changing modem settings:

Changing Modem Settings

To change the modem settings to force the modem to scan different technologies, use the following Cisco IOS command: 


Router# cellular 0/1/0 lte technology ?
auto  Automatic LTE Technology Selection
  lte   LTE
  umts  UMTS

Electronic Serial Number (ESN)

The ESN number is located directly on the modem label in hexadecimal notation. It can also be retrieved using the Cisco IOS CLI using the show cellular slot/port/module hardware command.

The sample output below shows the ESN number: 


Hardware Information
====================
Electronic Serial Number (ESN) = 0x603c9854 [09603971156]
Electronic Serial Number (ESN) = <specific ESN in hexadecimal> [specific ESN in decimal]
