| Product Impact |
Feature |
Description |
| Security |
As part of Cisco’s Resilient Infrastructure program and Cisco’s commitment to secure infrastructure, this release includes additional changes aimed towards continuing to make Cisco IOS XE more secure by default. Note that some of these changes may require operational changes if you are not following secure best practices. This release includes the following changes:
● The RADIUS client appends the Message-Authenticator attribute (Attribute 80 HMAC-MD5) to all outgoing Access-Request packets to mitigate cryptographic forgery and
Blast-RADIUS vulnerabilities (CVE-2024-3596).
● The RADIUS client drops incoming Access-Accept, Access-Reject, and Access-Challenge packets if the Message-Authenticator is absent or invalid. Ensure AAA servers (example, Cisco ISE) are configured to return Attribute 80.
● Outbound SSH connections enforce Trust-On-First-Use (TOFU). The device prompts to verify and store remote server host keys in the known-hosts database on first connection and validates against them on subsequent sessions.
● Proxy ARP is disabled by default across all routed interfaces, SVIs, and subinterfaces to reduce Layer 2 broadcast domains and prevent ARP spoofing. Configure the
ip proxy-arp command explicitly if required.
● The embedded web server daemon is disabled by default on factory configurations to restrict unauthenticated management access. Web UI and RESTCONF require explicit enablement of the
ip http secure-server command.
● The IOS XE device rejects unauthenticated NTP Mode 6 and Mode 7 control queries (monlist) to prevent NTP reflection and amplification DDoS attacks. Standard time synchronization (Modes 3 and 4) is unaffected.
● System logging timestamps automatically include the four-digit calendar year (service timestamps log datetime msec year) to standardize multi-year audit logs and SIEM compliance.
● Integrates Linux auditd inside Cisco IOx Guest Shell. All commands, system calls, and privilege escalation events (sudo) executed inside the container are forwarded to the host syslog facility.
● Warning messages are emitted on the console and logged to syslog whenever legacy insecure protocols (telnet, ftp, tftp, http) are enabled in the configuration.
● Real-time tracking of active insecure services is published to the operational database (operDB) and YANG data models, allowing management controllers (such as Cisco Catalyst Center) to monitor security compliance.

|
| Upgrade |
This feature provides enhanced security by converting legacy CIP passwords to the irreversible Type 8 (SHA-256) algorithm to resist cryptographic attacks. It ensures credential integrity and uninterrupted authentication across industrial deployments. |
|
| Enhanced Reliability |
FlexLink+ provides Layer 2 link redundancy without using STP. It supports active-standby failover on physical interfaces and EtherChannel bundles. VLAN load balancing lets both links forward traffic for different VLANs. After a failed link recovers, the preferred VLAN forwarding can be restored manually or automatically after a configured delay. |
|
| Security |
HTTPS servers disabled by default except for express setup |
Starting with Cisco IOS XE 26.2.1, HTTPS servers remain disabled by default, excluding express setup deployments which retain existing settings. |
| Security |
Cisco Industrial Ethernet switches can use ML-KEM-based key exchange with EAP-TLS 1.3 to provide quantum-resistant key establishment for MACsec connections. EAP-TLS derives keying material that MKA uses to establish secure MACsec communication between switches. |
|
| Security |
Cisco Industrial Ethernet switches can combine ML-KEM with traditional key-exchange algorithms to secure SSHv2 sessions. This hybrid approach provides quantum-resistant key establishment for secure remote management while retaining protection against classical attacks. |
|
| Upgrade |
This feature combines Precision Time Protocol with Resilient Ethernet Protocol to maintain millisecond-level time synchronization during network failures with <200 ms failover, eliminating PTP re-convergence delays that disrupt industrial applications. |

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, 170 W, 240 W, or 480 W) for the PoE budget, the PoE budget for the IE3x00 defaults to 125 W 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 480 W. The IE3400-8P2S with an attached IEM-3400-8P draws 67 W. With a 480 W capacity power supply, the maximum PoE budget that you should configure is (480 W - 67 W) = 413 W.
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 data sheet from the maximum capacity of the power supply. This is your maximum 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 10 Mbps or 100 Mbps speed in half-duplex mode
CRC errors were observed on the IE3200 and IE3300 platforms when the switch is configured with 10 Mbps or 100 Mbps 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 the 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 26.2.x.

Startup configuration is always read from flash
Starting with 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 configuration, 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 with 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 and install modes. Beginning in Cisco IOS XE Release 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 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.
