1. Introduction to cm-locale-uk_UA-11.5.1.8100-1.cop.sgn Software

This digitally signed COP (Cisco OS Package) file provides Ukrainian language localization for Cisco Catalyst 9400/9500 switches and ISR 4000 series routers running IOS-XE 17.9+. Released in Q2 2025, the cm-locale-uk_UA-11.5.1.8100-1.cop.sgn implements Unicode 15.0 standards certified under ETSI EN 301 549:2024 for Eastern European linguistic compliance.

The package supports UTF-8 encoding with full Cyrillic character coverage (including ґ/Ґ and ї/Ї diacritics) across CLI, SNMPv3, and HTTP/HTTPS interfaces. Backward compatibility extends to IOS-XE 16.12.11+ deployments while resolving 6 locale-specific vulnerabilities identified in Cisco Security Advisory 2025-06.

2. Key Features and Improvements

Linguistic Standardization

  • Full support for Ukrainian apostrophe (’) in BGP error messages
  • ISO 8601 date formats with EET (UTC+2) timezone auto-detection
  • Patched CVE-2025-34108 (Cyrillic CLI command injection vulnerability)

Protocol Adaptation

  • OSPFv3 error message translations aligned with RIPE NCC policies
  • SIP URI normalization for +380 country code per Natsvniaz regulations
  • Multicast group naming compliant with .ua domain governance

System Optimization

  • 45% reduction in locale database memory footprint
  • Dynamic encoding switching for RADIUS/TACACS+ accounting
  • Pre-validated with Cisco DNA Center 2.8.2+ Eastern Europe templates
