Cisco Catalyst IE9300 Rugged Series Switch
Cisco Catalyst IE9300 Rugged Series Switches provide rugged and secure switching infrastructure for harsh environments. It is suitable for industrial Ethernet applications, including manufacturing, utility substations, intelligent transportation systems (ITSs), rail transportation, and other similar deployments.
The switch fulfills the need for a high-density SFP, RJ-45, and Power over Ethernet (PoE) rack-, or wall-mount switch that can function as a software-defined (SD)-Access fabric edge. It provides end-to-end architectural uniformity in the Cisco Catalyst Center for Internet of Things (IoT) connected communities and extended enterprises.
In industrial environments, the switch can be connected to any Ethernet-enabled industrial communication devices. These devices include programmable logic controllers (PLCs), human-machine interfaces (HMIs), drives, sensors, and input and output (I/O) devices.
All Cisco Catalyst IE9300 Rugged Series Switches have 4 GB of DRAM, four alarm inputs, and one alarm output. Other I/O include the following:
· SD-cards socket
· Power input
· RJ-45 (RS-232) console
· Micro-USB console
· USB-A host port
This section provides a brief description of the new software features introduced in this release.

| 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. See Cisco Enterprise Networking Product Analytics Frequently Asked Questions. |

| This feature allows you to simplify network management and scale easily with VXLAN overlays on your existing infrastructure. BGP EVPN as the control plane ensures efficient MAC and IP distribution. |
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 begins 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.
