Product Impact: Ease of Use
Feature: IRM-1100-4S8I Expansion Module
Description: You can now enhance your IR1101 router's networking capabilities by enabling additional connectivity and I/O options with the newly introduced the IRM-1100-4S8I Expansion Module. This module adds four SFP ports and eight Digital I/O connections, providing greater flexibility for your network deployments.
Supported device: IR1101

Product Impact: Ease of Use
Feature: Support for jumbo frames
Description: You can now improve your network efficiency and optimize bandwidth usage by enabling support for jumbo frames on the IRM-1100-4S8I Expansion Module. This feature allows MTU sizes of up to 9216 bytes, facilitating larger data transfers and reducing overhead.
Supported device: IR1101

Product Impact: Software Reliability
Feature: IP Device Tracking on routers
Description: You can now enhance your network security and monitoring capabilities by enabling IP Device Tracking with SISF support on LAN ports. This allows for comprehensive IPv4 device monitoring and improved security posture through integrated device tracking.
Supported devices: IR1101 and IR1800

Product Impact: Ease of Use
Feature: VRF for the P-LTE-450 module
Description: You can now enable VRF to provision LTE450 parameters through the LTE450 management interface. You can also enable VRF on 450 PIM management interface to enable HTTP request from router to the webserver of P-LTE-450 and get response from the webserver of P-LTE-450.
Supported devices: IR1101 and IR1800 (For IR1800, P-LTE-450 is supported only on slot 0/4.)

Product Impact: Ease of Use
Feature: Product Analytics
Description: Cisco IOS XE Product Analytics collects device Systems Information for the purposes of understanding product usage, enabling product improvements and product development, and assisting in product adoption and sales support. Only summarized data of feature usage and statistical counters of configuration are collected. No personal identifiable information, such as MAC/IP addresses, usernames, custom configuration names, or user provided strings, are collected as part of Cisco IOS XE Product Analytics. Cisco processes this data following the General Terms, the Cisco Privacy Statement, and any other applicable agreement with Cisco.

Product Impact: Ease of Use
Feature: Inline Tagging on switch interfaces
Description: You can now implement CTS Inline Tagging to enable end-to-end Cisco TrustSec architecture without the complexity and scalability challenges of SXP peering, ensuring that the CMD header in Ethernet frames is carried through to the network security enforcement point.
Supported devices: IR1101 and IR1800

Product Impact: Ease of Use
Feature: Ignition Power management
Description: From Cisco IOS XE 17.18.1a release, Ignition Power Management is supported for Catalyst IR1800 Rugged Series Routers, which delivers intelligent power management to SD-Routing devices in vehicle deployments. This feature keeps the router powered and connected when the vehicle’s engine is running and automatically shuts it down to prevent battery drain when the ignition is off. You can easily set how long the router stays powered after the engine stops, thereby ensuring continuous connectivity when needed and efficient battery use when the vehicle is parked.
Supported devices: IR1800

Product Impact: Ease of Use
Feature: Raw Socket transport
Description: Raw Socket transport is a method to stream characters from one serial interface to another over an IP network using TCP or UDP as the encapsulation method. Raw sockets allow applications to bypass the standard TCP/IP stack and interact directly with the network layer (Layer 3) and the data link layer (Layer 2), therefore helping network traffic to be analyzed at a granular level. In Cisco IOS XE Release 17.18.1a, you can configure Raw Socket transport using Feature Parcels in Cisco SD-WAN Manager without configuring and managing multiple commands
Supported devices: IR1100, IR1800, IR8300

Product Impact: Ease of Use
Feature: Configure cellular band select for cellular interfaces on SD-Routing devices
Description: You can select specific frequency bands to which the device can connect to, allowing optimized connection depending on location and network availability. This configuration can be done using Feature Parcels in Cisco Catalyst SD-WAN Manager.
Supported devices: IR1100, IR1800, IR8140, IR8300

Product Impact: Ease of Use
Feature: Configure logging of crash dump events for cellular interfaces on SD-Routing devices
Description: You can configure the device to collect the crash dump logs by enabling the boot-and-hold mode on the device using the LTE modem crash-action boot-and-hold command.
Supported devices: IR1100, IR1800, IR8140, IR8300

Product Impact: Ease of Use
Feature: Enable diagnostic monitoring for SD-Routing devices
Description: You can enable diagnostic monitoring log capture for devices with cellular interfaces using Catalyst Cisco SD-WAN Manager.
Supported devices: IR1100, IR1800, IR8140, IR8300

New hardware features

Product Impact: Ease of Use
Feature: IRM-1100-4S8I Expansion Module
Description: Cisco IOS XE Release 17.18.1a introduces the IRM-1100-4S8I Expansion Module for IR1101 routers, adding four SFP ports and eight Digital IO connections for enhanced networking capabilities.
Supported device: IR1101
