ISE - Configuring RADIUS DTLS for RADIUS Traffic Encryption (with IOS XE Devices)
Carlos from Cisco's AAA team demonstrates configuring RADIUS over DTLS to encrypt network traffic, ensuring confidentiality by using peer certificates and mutual trust between devices.
MAIN POINTS FROM TRANSCRIPT
- RADIUS protocol lacks built-in encryption, requiring DTLS for confidentiality.
- Collect peer certificates for establishing a DTLS tunnel.
- Import certificates into both ISE and iOS XC devices for mutual trust.
- Configure network devices to support RADIUS over DTLS and verify success with authentication tests.
TAKEAWAYS
- DTLS enhances RADIUS security by encrypting network traffic.
- Certificates must be exported, imported, and configured correctly for DTLS.
- Mutual trust is established through certificate exchange between devices.
- Successful configuration is verified by a RADIUS DTLS handshake success indicator.
