Release Notes for Cisco Catalyst IR1101, IR1800, IR8140, and IR8340 Routers - Cisco IOS XE 17.16.x

New Features in Cisco IOS XE 17.16.x

Feature Name:802.1x authentication on IR1800 Wi-Fi module
Description:From this release, the Wi-Fi Interface Module (WIM) module supports 802.1x authentication on the concurrent Root radio using an RADIUS server, forwarding EAP packets to the IR1800 router via a service VLAN on the AP.

Based on the active connection, the router directs traffic to either the WGB uplink, the cellular backhaul, or the Ethernet link. The RADIUS server authenticates a wireless client and assigns it an IP address, enabling seamless traffic flow.
Supported Devices:IR1800

Feature Name:Access MEMS sensor data
Description:With this feature, you can now stream the accelerometer and gyroscope sensor data to the IOx through the TTY interfaces on the two platforms:
IR1833
IR1835
This feature is enabled by default once dead reckoning is enabled and does not require additional configuration
Supported Devices:IR1800

Feature Name:Cellular Universal Interface Module (UIM) Support
Description:The following hardware and corresponding UIMs are now supported on the IR8140:
IRMH-LTE7-NA-900 with P-LTEA7-NA
IRMH-5GR16SA-900 with PIM P-5GS6-R16SA-GL
Supported Devices:IR8140

Feature Name:Configure DR Module using Cisco Catalyst SD-WAN Manager
Description:The IR1833 and IR1835 routers incorporate a Dead Reckoning (DR) module that calibrates data to estimate a vehicle's location when the GPS signal is weak or unavailable. The Cisco Catalyst SD-WAN Manager facilitates the use of DR CLI commands through the CLI template to estimate GPS coordinates.
Supported Devices:IR1833 and IR1835

Feature Name:Enhancing P-LTE-450 Network Management Through SNMP MIB Objects
Description:In P-LTE-450 networks, routers can provide crucial quality metrics through Simple Network Management Protocol (SNMP) Management Information Base (MIB) objects. Specifically, Cisco IR1101 and IR1800 routers equipped with the P-LTE-450 Pluggable Interface Module (PIM) allows you to integrate seamlessly with existing SNMP-based management tools to report their status and quality metrics.
Supported Devices:IR1101 and IR1800

Feature Name:Managed Cellular Activation Support for Cisco Catalyst Heavy Duty Routers
Description:Specific universal interface modules of Cisco Catalyst IR8140 Heavy Duty Routers support the Managed Cellular Activation solution.The following PIDs are now supported:
IRMH-LTEA-EA-900
IRMH-LTE7-NA-900
IRMH-5GR16SA-900
Supported Devices:IR8140

Feature Name:Monitoring Radio Signal Parameters and GPS Coordinates of Cellular Telemetry using Syslog Messages
Description:The cellular telemetry feature collects the Radio Frequency (RF) parameters and Global Positioning System (GPS) coordinates from the cellular network and displays them at a fixed interval of 60 seconds. To view the RF parameters and GPS coordinates for the cellular interfaces, you can either use the show loggingcommand or check the console output.
Supported Devices:IR1100, IR1800, IR8140 and IR8340

Feature Name:mSATA LED Toggling
Description:With this feature, you can toggle the mSATA LED to turn it on or off while the mSATA storage is being used on the router.
Supported Devices:IR1100 and IR1800

Feature Name:Raw Socket Multi Host Capability
Description:Serial packets can now be routed to multiple IP hosts through Raw Socket Transport in controller and autonomous mode.

When a raw socket TCP server is enabled on an async line, it is connected to a programmable logic controller (PLC) or remote terminal unit (RTU) and establishes sessions with multiple TCP clients. Traffic from these PLCs/RTUs are sent by the raw TCP server to all the connected TCP clients. When a TCP client polls for data from a PLC/RTU, the response is sent to all connected TCP clients supporting redundancy between the clients in the control centers to ensure all clients update their database.

There is no new command introduced to enable this feature.
Supported Devices:IR1100 and IR8340

Feature Name:Support WiFi6 in CAPWAP/WGB concurrent Wi-Fi modes - IPv6 support for the CLI's
Description:From this release, Cisco Catalyst SD-WAN Manager and the YANG model support both static and dynamic IPv6 configuration in Workgroup Bridge (WGB) mode.

This enhancement allows the configuration of IPv6 on the Wi-Fi Interface Module (WIM) in WGB mode from the router which enables routers to obtain IPv6 addresses, collect metrics, and view configuration details seamlessly.
Supported Devices:IR1800

Feature Name:Support for MTU of up to 9216 bytes (Jumbo Frames) on IRM-1100-4A2T
Description:With this enhancement, Maximum Transmission Unit (MTU) of up to 9216 bytes (Jumbo Frames) are supported on the Ethernet Interfaces of the IRM-1100-4A2T.
Supported Devices:IR1101

Feature Name:EVPN VXLAN VLAN-Aware Service
Description:A VLAN-Aware EVPN instance (EVI) can be configured to map multiple subnets (L2VNI) to a single EVI. In this setup, a MAC-VRF is identified using a combination of the route-target and the ethernet-tag. To identify a specific bridge-table within a MAC-VRF, EVPN routes will advertise with the Ethernet Tag field set to a value that facilitates this identification. This functionality improves the router's interoperability.
Supported Devices:IR1101, IR8340 and IR1800
