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 PTP for your stacked Cisco IE9300 Rugged Series switches so they function as a unified network entity. You receive consistent, synchronized timing across the stack, making network management simpler and ensuring precise timekeeping for your critical applications. |
|
| This feature enables configuring Cisco switches as Media Redundancy Clients (MRC) within an MRP ring, acting as regular ring participants that forwards traffic and continuously monitor link status, reporting any failures to the ring manager (MRM). This approach enhances network resiliency and simplifies deployment, supporting rapid failover and compliance with industrial certification requirements. |
||
| Ease of use and Ease of setup |
REP Segment ID Auto-Discovery automates the configuration of Resilient Ethernet Protocol (REP) Segment IDs using CDP. This feature reduces manual effort and prevents mismatches for both standard REP and REP Fast protocols, making it easier to add switches to existing segments or create new daisy-chain segments. |
|
| 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. |
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.
