| Product Impact |
Feature |
Description |
| Security |
Resilient Infrastructure |
As part of the ongoing commitment to network security, this release introduces secure alternatives to legacy commands. These updates are designed to mitigate potential risks and assist in establishing a more robust and secure operational baseline. The identified insecure commands are categorized as: • Line transport: Updates to secure remote access methods. • Device server configuration: Hardening of server-side settings. • File transfer protocols: Transitioning to encrypted transfer methods. • SNMP: Enhancements to secure management traffic. • Passwords: Strengthening authentication and credential management. • Miscellaneous: General security improvements for various system functions. The show system insecure configuration command introduced in Cisco IOS XE 17.18.2 release lists all insecure commands configured on the device. For all detected insecure configurations during device boot or upgrade, error messages are displayed. In Cisco IOS XE 26.1.1 release, all insecure CLI commands are blocked by default to strengthen your network infrastructure. If your environment requires the use of a legacy command, you must enable the system mode insecure command in global configuration mode. • Recommendation: Do not use insecure mode. This mode is temporary and will be removed in a future release. Identify and replace all insecure commands with their secure alternatives. • Upgrade behavior: If you upgrade to Cisco IOS XE 26.1.1 release with insecure commands already present in the running configuration, the system mode insecure command is automatically added to your configuration to prevent service disruption. For more information, refer this document Cisco C9000 Switching IOS XE – Resilient Infrastructure Playbook. |
| Upgrade |
This feature enables Cisco Industrial Ethernet (IE) switches to interoperate with existing high available systems by providing robust controller failover using PROFINET S2 controller redundancy mode. It aims to minimize potential issues and downtime in the event of network or controller failures. |
|
| Software Reliability |
This feature enhances device security and network flexibility by setting Discovery and Configuration Protocol (DCP) operations to read-only mode. It safeguards the IP address, gateway, and device name from modifications, protects essential network settings to prevent unexpected connectivity loss, and remains compatible with LLDP, SNMP, and CDP. Additionally, it enables devices to carry out identification and basic network discovery. |
|
| Ease of use
|
Industrial Asset Auto-Discovery feature automatically identifies, and catalogs directly connected industrial devices without impacting network performance. This feature exports inventory data to a syslog server in JSON format, streamlining asset tracking, security enforcement, and the detection of unauthorized hardware. |
This section provides a brief description of the new hardware features introduced in this release.
IOS-XE 26.1.1
There are no new hardware features introduced in this release.
Syslog Warning on Reload for SSH Hostkeys: After a device reload, you may observe a syslog warning indicating insufficient key length for SSH hostkeys, even if a strong RSA or EC key is configured.
Note:
· In the syslog warning message “crypto key generate rsa modulus <modulus-size> label <label-name>”, the <modulus-size> and <label-name> represent the actual modulus size and label configured on the device.
· The SSH keypair association configuration is done using the command: ip ssh ec|rsa <keypair-name>, where <keypair-name> corresponds to the keypair name configured on the device.
Example:
· RSA
Warning Observed : INSECURE DYNAMIC WARNING - Module: SSH,
Command: crypto key generate rsa modulus <modulus-size> label <label-name>,
Reason: An SSH hostkey has been provisioned on the device with insufficient key length,
Remediation: Please provision an SSH RSA hostkey with minimum modulus size of 3072 bits for enhanced security,
Submode: exec,
Parent CLI: Not Applicable.
· EC
Warning Observed : INSECURE DYNAMIC WARNING - Module: SSH,
Command: crypto key generate ec keysize <modulus-size> label <label-name>,
Reason: An SSH hostkey has been provisioned on the device with insufficient key length,
Remediation: Please provision an SSH RSA hostkey with minimum modulus size of 384 bits for enhanced security,
Submode: exec,
Parent CLI: Not Applicable.
Ignore these warnings if you have already configured a strong key. The system applies the SSH keypair association (ip ssh ec/rsa keypair-name) after the boot process.
Once this configuration is active, SSH will use the correct key for secure connections.
Notice of changes introduced in the Cisco IOS XE 17.18.2 release and beyond
Cisco is committed to safeguarding our products and customer networks against increasingly sophisticated threat actors. As computing power and the threat landscape have evolved, some features and protocols currently in use have become vulnerable to attack. While more secure alternatives are now available, legacy protocols may still be in use in some environments.
To improve network security, reduce the attack surface, and protect sensitive data, Cisco will begin phasing out legacy and insecure features and protocols, encouraging customers to transition to more secure alternatives. This process will be gradual and designed to minimize operational impact. The first phase began with the Cisco IOS XE 17.18 release train. This is part of a broader initiative to make Cisco products more secure by default and secure by design.
Starting with the Cisco IOS XE 17.18.2 release and in future releases, Cisco software displays warning messages when configuring features or protocols that do not provide sufficient security such as those transmitting sensitive data without encryption or using outdated encryption mechanisms. Warnings also appear when security best practices are not followed, along with suggestions for secure alternatives.
This list is subject to change, but the following is a list of features and protocols that generates warnings in releases beyond the version Cisco IOS XE 17.18.1. Release notes for each release describes the exact changes for that release.
● Plain-text and weak credential storage: Type 0 (plain text), 5 (MD5), or 7 (Vigenère cipher) in configuration files.
Recommendation: Use Type 6 (AES) for reversible credentials, and Type 8 (PBKDF2-SHA-256) or Type 9 (Scrypt) for non-reversible credentials.
● SSHv1
Recommendation: Use SSHv2.
● SNMPv1 and SNMPv2, or SNMPv3 without authentication and encryption
Recommendation: Use SNMPv3 with authentication and encryption (authPriv).
● MD5 (authentication) and 3DES (encryption) in SNMPv3
Recommendation: Use SHA1 or, preferably, SHA2 for authentication, and AES for encryption.
● IP source routing based on IP header options
Recommendation: Do not use this legacy feature.
● TLS 1.0 and TLS 1.1
Recommendation: Use TLS 1.2 or later.
● TLS ciphers using SHA1 for digital signatures
Recommendation: Use ciphers with SHA256 or stronger digital signatures.
● HTTP
Recommendation: Use HTTPS.
● Telnet
Recommendation: Use SSH for remote access.
● FTP and TFTP
Recommendation: Use SFTP or HTTPS for file transfers.
● On-Demand Routing (ODR)
Recommendation: Use a standard routing protocol in place of CDP-based routing information exchange.
● BootP server
Recommendation: Use DHCP or secure boot features such as Secure ZTP.
● TCP and UDP small servers (echo, chargen, discard, daytime)
Recommendation: Do not use these services on network devices.
● IP finger
Recommendation: Do not use this protocol on network devices.
● NTP control messages
Recommendation: Do not use this feature.
● TACACS+ using pre-shared keys and MD5
Recommendation: Use TACACS+ over TLS 1.3, introduced in release Cisco IOS XE 17.18.1.
Cisco is committed to supporting customers through this transition. Subsequent releases in the Cisco IOS XE 17.18 train continues to support these features but displays warnings if they are used. Future release trains may impose additional restrictions on these features which will be communicated through release notes.
The changes introduced in 17.18 persist in 26.1.x and later versions.

This section lists the limitations.
PoE configuration on Cisco Catalyst IE3x00 Switch
Even when using power supplies that can provide up to a supported maximum (for example, 170W, 240W, or 480W) for the PoE budget, the PoE budget for the IE3x00 defaults to 125W regardless of the power supplies used. You can configure the power budget to use the maximum.
Note: Before changing the power budget, the minimum power requirements for the switch need to be considered as well. Please refer to the data sheet for your switch for more details.
The attached power supply powers the IE3x00 switch operation as well as PoE power. When increasing the maximum PoE budget, you must subtract the power draw of the IE3x00 switch from the capacity of the attached power supply. You do so to prevent the IE3x00 switch from overdrawing the capacity of the attached power supply. For example, the IE3400 switch with an expansion module supports a maximum PoE budget of 480W. The IE3400-8P2S with an attached IEM-3400-8P draws 67W. With a 480W capacity power supply, the maximum you should configure the PoE budget is (480W-67W) 413W.
To use the power supply's maximum supported wattage for the PoE budget, configure the power supply max wattage in global configuration mode as follows:
1. Verify the maximum amount that the power supplies support for the PoE budget.
2. Subtract the operating power of the IE3x00 switch according to its datasheet from the maximum capacity of the power supply. This is your max PoE budget.
3. Enter power inline max max-wattage to increase the PoE budget based on the power supplies used.
4. max-wattage is the maximum available PoE power.
IE3200 and IE3300 with 10Mbps or 100Mbps speed in Half-Duplex Mode
CRC errors were observed on the IE3200 and IE3300 platforms when the switch is configured with 10Mbps or 100Mbps speed in half-duplex mode.
As a workaround, configure no ptp enable on the half-duplex interface. This improves ingress and egress latencies considerably and ensures that there are no late collisions (and therefore, no CRC errors).
The issue and workaround apply to Cisco IOS-XE releases 17.3.5 and later.
L3 ACL limitation on usage of L4OP in ACLs
Layer 4 Operator (L4OP) in ACLs is limited by the hardware to a maximum of 8 L4OP (range and gt) for UDP and 8 L4OP for TCP, for a total of 16 global L4OP. Keep in mind that the range operator consumes 2 L4OP.
The L4OPs include: gt (greater than), lt (less than), neq (not equal), eq (equal), range (inclusive range).
Note: The eq does not consume L4OPs. For more information see QoS Configuration Guide.
Refer to Cisco IOS-XE Migration Guide for IIoT Switches for software upgrade and downgrade information for Cisco Catalyst IE3x00, IE3400 Heavy Duty, and ESS3300 Series Switches, Release 26.1.x.
This section lists the hardware support information.
SSH algorithms for common criteria certification limitation
Starting from Cisco IOS-XE Release 17.10, the following Key Exchange and MAC algorithms are removed from the default list:
● Key Exchange algorithm:
◦ diffie-hellman-group14-sha1
● MAC algorithms:
◦ hmac-sha1
◦ hmac-sha2-256
◦ hmac-sha2-512
Note: You can use the ip ssh server algorithm kex command to configure the Key Exchange algorithm and the ip ssh server algorithm mac command to configure the MAC algorithms.
IOx support for Cisco Catalyst IE3300 Switches
To see if the IE-3300-8P2S switch or IE-3300-8T2S switch supports IOx application environment, check the Hardware Version ID on the switch label. The Hardware Version ID is in the upper-right corner of the label, as shown in the following illustration. Support for the feature is available only with Hardware Version ID 06 or later. In the following illustration, the Version ID appears as "V06" at the end of the string inside the red rectangle in the upper-right corner of the label.
You also can see the Version ID by entering the show version command and examining the output, as shown in the following example:

IE-3300-8U2X and IE-3300-8T2X switches have supported IOx since the Cisco IOS-XE 17.4.1 release.
Startup configuration is always read from Flash
From Cisco IOS-XE release 17.10.1, the startup configuration is always read from flash. The latest configuration is available only in flash when you save the running config, irrespective of the booted media (for example, flash, sdflash, or usbflash) and the boot mode (install or bundle). If a switch cannot find a configuration in flash, it will try to find one in sdflash.
Note: Starting from the Cisco IOS-XE release 17.10.1, you can configure Cisco Catalyst embedded switches to use USB Flash as the primary boot device.
SMU installation: Boot in Install mode
Software Maintenance Upgrade (SMU) installation is no longer supported in bundle mode. Previously, SMU installation was supported in both bundle boot and install mode. Beginning in Cisco IOS-XE 17.9.1, SMU supports patching using install mode only.
SMU installation stops if the device is booted up in bundle mode and syslog messages are displayed. You must boot the switch in install mode to support SMU installation.
If the device is booted up in install mode, SMU installation continues to work as before.
IE3400: Hardware changes may require action
Some hardware components on the Cisco Catalyst IE3400 Rugged Series and Cisco Catalyst IE3400 Heavy Duty Series switches have changed. The changes, which are automatically handled by the IOS-XE software, do not affect switch functionality or the ordering process. New units shipped after May 31, 2022 have the hardware change.
However, you may need to upgrade the software, depending on which base switch and expansions module you have, as shown in the following table.
Note: For detailed information about affected hardware versions, supported software releases, and instructions for different scenarios, see Field Notices on Cisco.com.
| If you have… |
then… |
| Older versions (shipped before May 31, 2022) of the base switch and expansion module |

FPGA profile
FPGA Profile is supported in Cisco IOS-XE release 17.8 and later. In a Cisco IOS-XE upgrade from an earlier release that does not support FPGA Profile, for example, an upgrade from Cisco IOS-XE 17.7.1 to 17.8.1, the default FPGA Profile is installed. Any features controlled by FPGA Profile that are configured in the switch running the earlier release and that are not included in the default profile will be rejected.
Note: This feature is supported for Cisco Catalyst IE3400 Rugged Series Switches and Cisco Catalyst IE3400 Heavy-Duty Series Switches.
For example, CTS IPv6 is not supported in the default profile, so CTS IPv6 configurations are rejected during bootup after the upgrade. Similarly, after a Cisco IOS-XE upgrade where the cts-ipv6 profile is loaded, existing PRP configurations are rejected upon bootup.
To keep the existing profile and feature configurations after an upgrade:
1. After booting the switch, selected the required FPGA Profile as described in "Changing the FPGA Profile", in System Management Configuration Guide, Cisco Catalyst IE3x00 Rugged, IE3400 Heavy Duty, and ESS3300 Series Switches, chapter "Configuring FPGA Profile".
Do not copy running-config to startup-config or write memory.
2. Reload the switch.
The required feature configurations will not be discarded because they are supported by the selected profile.

Automatic boot loader upgrade
When you upgrade from the existing release on your switch to a later or newer release for the first time, the boot loader may be automatically upgraded, based on the hardware version of the switch. If the boot loader is automatically upgraded, it will take effect on the next reload.
For subsequent Cisco IOS-XE releases, if there is a new bootloader in that release, it may be automatically upgraded based on the hardware version of the switch when you boot up your switch with the new image for the first time.
Caution: Do not power cycle your switch during the upgrade.

Software installation options
To install and activate the specified file, and to commit changes to be persistent across reloads, enter this command: install add file filename [ activate commit]
Note: For the install command to be successful, it is recommended to have a minimum of free space that is twice the size of the image in flash. If there is not enough space available in flash, you are advised to free up space in flash either by issuing the install remove inactive command or to manually clean up the flash by removing unwanted core files or any other files that occupy a large amount of space in flash.
