■ Image Information and Supported Platforms
■ Caveats
The Cisco IR1101 Industrial Integrated Services Router is a next generation modular industrial router which has a base module with additional Pluggable Modules that can be added. The Pluggable Module provides the flexibility of adding different interfaces to the IR1101 platform, for example, a cellular module.
The IR1101 ISR also has an Expansion Module that adds key capabilities such as dual LTE Pluggables, mSATA SSD FRU, SFP, and Digital GPIO connections.
Cisco IR1101 Industrial Integrated Services Routershows the IR1101. IRM-1100-SPMI Expansion Module shows the IRM-1100-SPMI Expansion Module. IRM-1100-SPMI Expansion Module Details describes the details of the Expansion Module.
Note: Complete details on the IR1101 and both Expansion Modules can be found in the IR1101 Industrial Integrated Services Router Hardware Installation Guide.

Note : The IR-1100-SP Expansion Module is the same as the IR-1100-SPMI module, without the Digital I/O and mSATA components.
Note : You must have a Cisco.com account to download the software.
Cisco IOS-XE releases generally follow the schedule as follows:
■Standard Maintenance (SM) Release - Defect fixes for 6 months, and PSIRT fixes for 6 months.
■Extended Maintenance (EM) Release - Defect fixes for 24 months, and PSIRT fixes for 12 months.
There are typically 3 major releases each year:
■End of March - Standard Maintenance

This release has the following limitations or deviations for expected behavior:
■Downgrading from 16.12.1 to 16.11.1 x
Symptoms : If an IR1101 with RJ45 Gig0/0/0 WAN is downgraded from 16.12.1 to 16.11.1 x or earlier, it will cause the Gig0/0/0 to fail to come up because its media-type is set to media-type sfp. The problem occurs because 16.12.1 or later automatically selects the correct media-type of the Gig0/0/0 interface, while 16.11.1x and earlier does not have that capability.
Workaround : Specifically set the correct media-type for the Gig0/0/0 interface (e.g. media-type rj45) prior to any downgrade.
■When operating on release 17.1.1, if you install a P-LTEA-EA/P-LTEA-LA pluggable module into the Expansion Module (IRM-1100-SP or IRM-1100-SPMI), it will not function correctly. Upgrading to release 17.2.x will correct this issue.
X.25 is an ITU standard for packet switching Wide Area Network (WAN). This is used in the Telecommunication industry over serial interfaces that are replaced by IP Network. An X25 connection can be established by using a PAD connection similar to Telnet/SSH. The IR1101 router has only one asynchronous serial interface where features of X25 are not supported. However, we can communicate to the X25 edge devices using by using feature TCP over X25 (XOT). With XOT, we can directly establish a PAD connection to X25 edge devices. Also, we can assign default or customized profiles to the access-groups by changing various parameters of X25 packets.
For additional information about XOT for IOS-XE, see the following:
Wide-Area Networking Configuration Guide: X.25 and LAPB, Cisco IOS XE
The YANG models supported for the call-home feature are similar to the earlier releases of Cisco-IOS-XE, and the same is supported on 17.1 release of IOS-XE on IR1101. The following references are available for earlier YANG models:
https://github.com/YangModels/yang/tree/master/vendor/cisco/xe/1651
For additional information about call-home for IOS-XE, see the following:
Software Activation Configuration Guide, Cisco IOS XE Release 3S
Similar to YANG models, there is support on IOS-XE for open source models defined by Google and is referred as Google Network Management Interface (GNMI). Configurations of GNMI can be verified either with Secure or Insecure Mode.
Secure Mode establishes secure connection using OpenSSL certificates between client and server. It sends GNMI telemetry updates using open source gnmi_cli tool.
Insecure Mode sends GNMI telemetry updates between client and server using open source pygnmi tool.
For additional information about GNMI Telemetry see the following reference:
The Cisco IOS XE 17.1.1 introduces support for the Cisco IOS XE YANG model for the Scada System. Previous releases already provided Yang models in other areas.
https://github.com/YangModels/yang/tree/master/vendor/cisco/xe/17111.

USB flash drives offer inexpensive and easy storage space for the routers to store the images, configuration files and other files.
Note : The IR1101 supports ext2 and vfat file systems for USB flash drives.
The IR1101 supports hot plug/unplug of USB flash drives. To access the USB flash drive, insert the device into Router's USB interface. Once the USB is recognized, an alert message is seen on the console:
After this message is seen, the USB flash drive is accessible. Users can access the USB contents using the dir usbflash0: command:
Contents can be copied to and from the USB flash drive using the copy command. Once the copy is complete, a log message showing number of bytes copied is displayed.
While hot plug/unplug of a USB flash drive is supported, the functionality comes with security vulnerabilities. To prevent users from copying sensitive information to the USB flash drive, USB enable/disable functionality has been added.
By default, the USB flash drive is enabled. If a user wishes to disable USB, they can do so using the disable command:
Once the USB flash drive has been disabled, the file system is not shown on the Device and syslog messages will not be displayed when the USB is inserted. Users will not be able to access the contents of the USB.
The USB is enabled by issuing a ' no ' with the disable command:
The USB status can be displayed using the following command:
Note : A Day 0 configuration is defined as a device that is fresh out of the box with no startup-configuration.
Effective with IOS-XE Release 17.1.1, the Day 0 Web User Interface (WebUI) will be supported on the IR1101. Day 0 WebUI is supported only on LAN ports. These are FastEthernet ports 0/0/1 – 0/0/4 on the IR1101. Connect either a Windows, Linux or Mac PC/Laptop to one of the LAN ports of the IR1101 and boot the router on Day 0. The PC/Laptop should be configured to obtain an IP address through DHCP.
Once the router boots up in Day 0, the PC/Laptop will acquire IP address in 192.168.1.x network and can access WebUI using the IP address of 192.168.1.1 with any browser. After the configuration is applied through the WebUI, the router will display the message "Day 0 config done. Stopping autoinstall".
For additional information, see the IR1101 Software Configuration Guide.

Benign bootup warning messages appear on the console.
Symptom : The following messages are seen during bootup:
Workaround : Ignore these messages. They are not indicating any problem, and will be removed in a future release.
The speed range should only show 10 or 100 for FE ports in the IR1101 switchport template.
Symptom : The FE ports can only be set to 10 or 100 Mbps. The template allows the full range of 10/100/1000/10000.
Workaround : Only use the 10 or 100 Mbps selections.
On the IR1100 with the cEdge image, the upgrade fails due to insufficient disk space.
Symptom : Occurs with an image upgrade of cEdge devices using vManage and returns a failure of insufficient flash space.
Workaround : There are two options:
1. vManage checks required diskspace before downloading the image and taking 40 min time and 4G bandwidth. First delete files to make room.
2. Limit tracelog on the flash to retain 2x 430MB (current image size) free space.
vManage: GPS enabling feature from vManage template fails.
Symptom : From AWS vManage, attempting to attach device-template, including a Cellular GPS feature-template, fails. Removing the GPS template allows the attach of template to progress to the next stage where it shows the configuration differences. With the GPS feature-template selected, it always shows as failed.
Workaround : Remove the GPS template.
vManage: CPU util shown by CLI doesn't match reported by vManage realtime.
Symptom : The CPU util doesn't match when comparing what was on IR1101 CLI sh plat soft status control brief with the realtime device CPU util on vManage. The vManage seems to be reporting CPU from sh proc cpu older IOS version CLI.
Workaround : Check each device using CLI commands
vManage: Allow cellular modem firmware image upload and upgrade via vManage.
Symptom : Currently, vManage doesn't have a device/feature template or Software Repository + Upgrade mechanism of cellular modem.
Workaround : There is no workaround, functionality to be added in a future release.
WP7610 should support band 66, but support is missing in IOS.
Workaround : There is no workaround, will be fixed in a future release.
Whenever firmware switches from GEN to ATT on a WP7610 modem, a QMI channels initialization message is seen.
