Introduction

In Cisco IOS Release 15.2(4)M3, the multimode 4G LTE feature is supported on the Cisco 819 ISRs. The Cisco 819HG-4G and Cisco 819G-4G routers have the Sierra Wireless multimode modem embedded in them and support 4G LTE and 3G cellular networks.

Summary of Changes Between Cisco IOS Release 15.2(4)M3 and Later

For Cisco IOS Release 15.2(4)M3 or later image, the external link recovery script is not required. Ensure that the link recovery script is removed from Flash before upgrading to Cisco IOS Release 15.2(4)M3 or later, which also contains an embedded modem link recover mechanism that eliminates the need for link recovery scripts. Ensure that the cell_recovery_vx.tcl and cel_cli_vx.tcl scripts are removed from router flash, where x stands for the script version number that is in use, for example, cell_recovery_v2.tcl and cel_cli_v2.tcl.

The Cisco IOS Release 15.2(4)M3 or later image also requires a mandatory upgrade to the latest versions of modem firmware. The new modem firmware versions contain significant modem stability enhancements. Cisco IOS Release 15.2(4)M3 or later should not be installed without upgrading the LTE eHWIC modem firmware to the appropriate 3.x release. The following are the new firmware versions supported on the LTE SKUs in Cisco IOS Release 15.2(4)M3 or later:

•C819(H)G-4G-V : 3.5.10.6

•C819(H)G-4G-A : 3.5.10.2

•C819(H)G-4G-G : 3.5.19.4

Cisco IOS Release 15.2(4)M3 also includes an upgrade to a newer and more stable version of vendor-provided SDK Version 1.8.0 that provides support for the new modem firmware.

The modem firmware files and the associated documentation for upgrading the modems are available at the following locations:

•EHWIC-4G-LTE-V : 3.5.10.6 - http://software.cisco.com/download/release.html?mdfid=284772061&flowid=40082&softwareid=284285628&release=3.5.10.6&relind=AVAILABLE&rellifecycle=&reltype=latest

Software Compatibility

For ISRs with EHWIC-4G-LTE-V and C819(H)G-4G-V-K/9, the use of Cisco IOS Release 15.2(4)M3 or later requires LTE modem firmware 3.5.10.6.

---

Note The LTE modem firmware will be available in near future. Do not use Cisco IOS Release 15.2(4)M3 or later on ISRs with LTE eHWICs until the LTE modem is upgraded.

---

Cisco IOS Release 15.2(4)M3 or later includes Verizon Wireless LTE modem drivers that operate with the latest MC7750 LTE modem firmware. Due to backward compatibility issues with the existing LTE modem firmware (1.0.9.3), Cisco IOS Release 15.2(4)M3 or later should be used only after upgrading the existing LTE modem firmware to the Release 3.5.10.6, or with the new EHWIC-4G-LTE-V and C819(H)G-4G-V-K/9 units with firmware 3.5.10.6 factory loaded.

Check the LTE modem firmware using the Cisco IOS command show cellular 0/x/0 hardware (for EHWIC-4G-LTE-V, with x being the EHWIC slot number) or the show cellular 0 hardware command (for C819(H)G-4G-V).

The latest certified firmware version for your carrier having Cisco IOS compatibility is available at http://www.cisco.com/en/US/prod/collateral/modules/ps5949/ps7272/datasheet_c78-710314.html.

Limitations and Restrictions

•Currently, cellular networks support only outgoing calls.

•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.

•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.

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

•Public Land Mobile Network (PLMN) CLIs exist but the feature is not supported in this release.

•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.

•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.

•GPS is not supported in Release 15.3(3)M.

Caveats

•Open Caveats—Release 15.3(3)M

•Resolved Caveats—Release 15.2(4)M3 and Later

Open Caveats—Release 15.3(3)M

•CSCui61199

Modem Type: All LTE modems.

Symptom: Inablility to configure the cellular profile username and password through the CLI if a 32 character password is required. This problem will be fixed in 15.3(3)M1.

Condition: The username and password configuration issue occurs when a 4G modem connects in UMTS mode to a 3G network.

Workaround: None

•CSCug04917

Modem Type: AT&T and Global LTE.

Symptom: The cellular interface may reset after deleting SMS messages from a full SMS SIM.

Condition: When the system sends traffic over cellular link, the LTE modem continues to receive SMS messages even though the SIM card has reached its full capacity.

Workaround: Setup the FTP server path for auto SMS archiving when the SIM/USIM is full, or delete SMS messages before the SIM is full.

•CSCue48693

Modem Type: Verizon

Symptom: Low throughput is seen when uplink carries traffic.

Condition: Send IMIX traffic rate 16 Mbps and greater to the uplink.

Workaround: None.

•CSCue41706

Modem Type: All LTE modems.

Symptom: UUT SMS special characters sent does not match receiving device.

Condition: When a special character (`\', `$', `@') is sent by way of SMS from different carriers.

Workaround: None

•CSCts51164

Modem Type: All LTE modems

Symptom: Modem becomes unresponsive.

Condition: This symptom is observed when a small packet traffic (64 B) goes downlink at the rate of 35 Mb/s.

Workaround: In the context of small packet traffic (64 B), lower the downlink rate to 25 Mb/s.

•CSCtw47467

Modem Type: AT&T

Symptom: The MC7700 modem fails to ping to the network.

Condition: This symptom is observed in the context of pings when a packet size of 1045 B or greater is present and has the Access Point Name (APN) set to Broadband.

Workaround: Use packet size of 1044 B or smaller.
