Release Notes for the Cisco Catalyst IR1101 Rugged Series Router - Release 17.1.1
The following release notes support the Cisco IR1101 router. These release notes are updated to describe new features, limitations, troubleshooting, recommended configurations, caveats, and provide information on how to obtain support and documentation.
Updated : July 19, 2021
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.

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.
The following features are included in the Cisco IOS-XE release 17.1.1:
Support for the X25 over TCP (XOT)
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
Support for Model Driven support for GNMI Telemetry Dial-In
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:
Programmability Configuration Guide, Cisco IOS XE
Option to Enable or Disable USB Access
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:
Aug 1 11:08:53.198 PDT: %IOSD_INFRA-6-IFS_DEVICE_OIR: Device usbflash0 added
After this message is seen, the USB flash drive is accessible. Users can access the USB contents using the dir usbflash0: command:
5 drwx 512 Aug 23 2019 10:42:18 -07:00 System Volume Information
6 -rwx 35 Aug 27 2019 17:40:38 -07:00 test.txt
206472192 bytes total (206470144 bytes free)
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.
Device#copy flash:test.txt usbflash0:
Destination filename [test.txt]? <Enter>
35 bytes copied in 0.020 secs (1750 bytes/sec)
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:
Device(config)#platform usb disable
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.
% Invalid input detected at '^' marker.
The USB is enabled by issuing a ' no ' with the disable command:
Device(config)#no platform usb disable
The USB status can be displayed using the following command:
Device#show platform usb status
Day 0 Web User Interface
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.
Caveats describe unexpected behavior in Cisco IOS releases. Caveats listed as open in a prior release are carried forward to the next release as either open or resolved.

Benign bootup warning messages appear on the console.
Symptom : The following messages are seen during bootup:
WARNING: Loaded FDT at random address 0xB87D2000.
WARNING: There is a risk of accidental overwriting by other code/data.
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.
