- Not validated for use with Network Advantage license features
Secure Software Access
While Cisco’s official distribution channel remains the Cisco Software Center, authorized partners like IOSHub provide verified download mirrors with MD5 checksum validation. Users should always:
- Confirm the SHA-512 hash matches
2f85e5c6fe9a...(full hash available upon authentication) - Validate digital signatures using Cisco’s published public key bundle
- Review the Amsterdam 17.3.x Release Notes for upgrade considerations
