Boot Time Reduction

Enhancements were made to optimize the amount of time it takes to go from power up to fully functional.

Copper SFP Support

Support for the following copper SFPs has been added:

• GLC- T: (0 to 70°C) — Cisco Part Number is 30-1410-04
• SFP-GE-T: (-5 to 85°C) — Cisco Part Number is 30-1421-02

Additional details can be found in the respective Hardware Installation Guides at:

Cisco 800 Series Industrial Integrated Services Routers

USB Support

Previous to 15.6(3)M, the USB devices, which are connected to external USB port could be emulated on the Guest OS through OHCI mode only. With this feature Hypervisor will be enhanced to support EHCI emulation to Guest OS.

Serial Device Configuration

Previously, the Guest OS could not configure the physical serial port on the device. The serial port configuration (e.g. baud rate change) of the serial port needed to be done in IOS.

With 15.6(3)M, Hypervisor and IOS are enhanced so that if the Guest OS changes the virtual serial port configuration, it notifies IOS, and IOS applies the configuration to the physical serial port.

Command line changes consist of the following:

A new option is appended to allow the baudrate, databits, stopbits and parity propagation from Guest OS. If "propagation" is present, the control parameters will be passed from Guest OS to IOS physical port. Otherwise it functions as before.

The serial port control parameters included in the propagation are: baudrate, databits, stopbits and parity.

Memory Allocation Optimization

Improvements have been made in the memory allocation optimization between VDS, IOS and GOS on the IR800. Previously, the 2GB RAM was allocated as follows:

• VDS: 512MB
• IOS: 512MB
• Guest OS: 725MB
• Remainder: used by Hypervisor (e.g. device share memory)

Now with optimization, the VDS memory was reduced to give at least 1GB to the Guest OS.

Digital Alarm Support for CGR 1000 Series routers

The routers now support the following Digital Input and Output command-line interface (CLI) commands:

CGR 1240:

Alarm port contact (Input Alarms):

Alarm port relay (Output Alarms):

CGR 1120:

Alarm port contact (Input Alarms):

Alarm port relay (Output Alarms):

You can find new commands in the CGR 1000 Series Hardware Installation Guides at:

Enhancements to Mesh Security

To better fine tune mesh networks some hard coded parameters have been made configurable. Four CLI commands have been added to configure key exchange timeout, key exchange retries, max key exchange failure, and key exchange permanent timeout. Another four CLI commands are added to show the values of these parameters. These commands are as follows:

Compute Module for CGR 1000 Series routers

The Connected Grid Router (CGR) Compute module is a modular, hardened server that can be inserted into CGR 1000 routers. The Compute module functions as a fog computing node at the edge of the network.

The Compute module runs Cisco IOx, a Hypervisor architecture, in which Cisco IOS software runs as a Virtual Machine (VM) alongside a Windows VM. Customers can run Internet of Things (IoT) applications on the Linux VM and can also connect legacy networking technologies through a network interface card. For example, applications hosted on the router can collect system information by sniffing and processing packets or by querying network information from IOS using APIs. By acquiring this information, the applications can use it to control and query other network devices using IoT protocols.

Compute Module SKUs:

Support for the Cisco LoRaWAN Interface

The Cisco Interface Module for LoRaWAN extends connectivity of IoT routers to include low-power wide-area (LPWA) access. It adds a ruggedized remote LoRaWAN radio modem interface to create a gateway between the Cisco Field Network Director and a partner’s LoRa network server.

Note You need to install he Actility Thingpark LRR software for the Cisco LoRaWAN Interface Module to work.

Cisco IOS Release 15.6(3)M

The following sections list caveats for Cisco IOS Release 15.6(3)M:

Open Caveats

• CSCva66036

After upgrading the modem on a CGR1240, the modem needed to be power-cycled in order to bring it up.

Workaround :

None

• CSCva32006

When executing a series of show and configuration commands quickly on an ISR-G2, via an SSH session, an SSH Process Thrash message is generated.

Workaround :

When executing multiple commands, wait a few seconds between each command.

• CSCuu49331

LED status report for PoE is inconsistent across different commands.

Workaround :

None

• CSCuy79750

After completion of a bundle installation, the Guest OS might not function.

Conditions :

Perform a bundle installation with the Guest OS running. After the bundle installation is completed with Guest OS updated, the device needs to be reloaded.

Workaround:

It is recommended to shutdown the Guest OS before performing a bundle install. After the bundle installation is completed, the device needs to be reloaded.

• CSCut75469

IR829 is not getting GPS data after router bootup

Conditions :

After router bootup, sometimes the modem is up but does not get GPS data.

Workaround:

Power cycle the modem.

• CSCuz40849

Cisco IOS cannot decode certificate lifetime past the year 2099

Conditions :

The validity end-time for either CA certificate or certificates must be 2099 or earlier. Cisco IOS cannot decode dates past 2099. BER/DER decoding failure will be generated during authentication and enrollment phases.

Workaround:

None

• CSCuz51085

Registration on the CGR1K, IR800, and C819 will always fails after a flash format or folder deletion.

Conditions :

Once a device has been tunnel-provisioned (including those that have been registered to FND), any attempt to format its flash partition or delete the managed folder on the flash will cause any future registration (e.g. after a router reload, or a fresh ZTD operation) to fail.

Sample Registration Failure :

java.io.IOException: Failed to retrieve inventory from device. Reason: [invalid cli command] Sent [[show iox host list detail | format flash:/managed/odm/cg-nms.odm, show iox application list | format flash:/managed/odm/cg-nms.odm]]

Workaround:

Access the FND's Oracle database and delete the MD5 checksum of the updated odm file for these eid's from the database.

• CSCuz66824

The alarm contact configuration command syntax changed in 15.6(3)M.

Conditions :

In the 15.6(3)M or later releases, there is a slight change in the command syntax for the alarm contact configuration. If alarm contact is configured in IOS images prior to 15.6(3)M, and the device is upgraded to15.6(3)M, the alarm contact will need to be reconfigured using the new command syntax. Otherwise, the alarm contact setting will be lost.

Command Syntax Difference:

Pre-15.6(3)M with hyphen between alarm and contact:

Post-15.6(3)M with no hyphen between alarm and contact:

Workaround:

Reconfigure the alarm contact after upgrading to 15.6(3)M.

• CSCuu49331

LED status report is inconsistent across different commands

Conditions : PoE LED will go back and forth between yellow and green when there is a PoE device in deny power state. Typing show platform led or show platform led summary will sometimes show yellow, sometimes shows green.

Workaround : Remove the device that has been denied for power allocation

• CSCuu60617

Media-type rs485 is configurable under IR800 serial port 0 interface (async1), however the serial port 1 (async1) interface does not support media-type rs485.

Conditions : When you configure 'media-type rs485" under the async1 interface, the configuration is acceptable.

Workaround : None

• CSCux43383

On the IR829 with a 4GModem, the modem can enter into an unknown state after several modem resets.

Conditions : After 100+ modem resets and attach to BSS, the modem enters into a state where it no longer displays modem info on IOS ( show cellular 0 all). It neither attaches to the BSS or sends IP traffic. Modem seems to respond to the AT commands.

Workaround : None

• CSCuy83574

Enabling GPS on the CGR1000 3G/4G cellular controller will lock up the console.

Conditions : The regular GPS settings for 3G or 4G cellular controller in the CGR1000 routers must not be used. Cellular modem-based GPS in CGR1000 routers is not supported.

Workaround : Only a CONFIG RESET button recovery may help to restore the CGR1000 back to working condition.

• CSCuy91636

CGR1000 GOS image version is not matching the version in the filename.

Conditions : The version in the CGR1000 GOS file name " cgr1000-ref-gos.img.1.30.gz " is 1.30, but after a bundle install and restarting the IOX VM, the GOS version being retrieved from " sh platform guest-os " is 1.29.

Workaround : None

• CSCuy91651

Inconsistent version numbering for the Ref-GOS image name in the IR800 bundle image.

Conditions : In the IR800 bundle image, the REF GOS image name is: ir800-ref-gos.img.2.3.gz.

Installing the GOS image will produce this version string:

Installation: Cisco-GOS,version-1.0.0.2

Guest OS status:

I nstallation: Cisco-GOS,version-1.0.0.2

The IR800 GOS image is properly versioned in the form: ir800-ioxvm-1.0.0.x

Workaround : None

• CSCvb55487

IR8x9 router reboots after setting up energy wise and executing show energywise command.

Conditions : Energy wise has to be set on the router. If it is not show energywise command returns information that it is disabled.

configure terminal

energywise domain iss-lab security shared-secret 0 energywisesecret

end

show energywise

After last command router reboots itself.

Workaround : None

• CSCvf75957

Problem Description :

Bundle install failure/timeout, IOx failure

Symptoms:

1. ping to VDS fails:

2. bundle install times out

3. iox applications are not accessible anymore

Conditions:

Typically, when the router is left idle for many weeks and months, there is a possibility to observe this when upgrading to the next software image.

Root Cause:

Root cause was that dual modem logs in VDS were not rotating and size increased in time. Due to lack of memory, bundle install attempts failed. Reload the router before reattempting bundle install and image upgrade.

Issue is seen in all software images supporting dual modem [15.6(3)M and beyond]

Workaround :

Reload IOS and system will recover.

• CSCvd41974

Problem Description :

On IR829 and IR809 platform, there is a Wpan2 interface shown by default in 15.6(3)M2 and beyond software images.

Condition :

The show run command will by default show an additional interface, regardless of whether LoRa modem is attached or not.

Workaround :

None

Closed Caveats

• CSCuy45856

On the CGR1000 series, bootstrap and flash partitions get corrupted after upgrade.

Workaround :

Users are highly recommended to upgrade their CGR1000 routers running any previous releases to the 15.6(3)M version to avoid potential flash corruption, which may completely corrupt and wipe out all the files on both bootstrap and flash partition, rendering the router un-bootable.
