To Create a DTLS Profile

To create a new DTLS Profile:

1. Click New DTLS Profile. The Create New DTLS Profile window opens.

2. Use the following table to configure the options and then click Save.
   Table 1: DTLS Profile Parameters
   

   Parameter	Description
   Name	Specifies the name of the DTLS Profile created. The value ranges up to 23 characters.
   Handshake Timer	Specifies the time in which the DTLS handshake must be completed. The timer starts when the TCP connection is established. Must be 1 - 60 seconds; default is 5.
   Session Resump Timer	Specifies the DTLS session resumption period for which cached sessions are retained (in seconds). DTLS allows successive connections to be created within one DTLS session and the resumption of a session after a DTLS connection is closed or after a server card failover, without repeating the entire authentication and other setup steps for each connection, except when the space must be reclaimed for a new session. Must be 0 - 86,400 seconds; default is 300.
   Cipher Suite1	Use this parameter to specify the first DTLS Cipher Suite choice for this profile. nosuite rsa-with-aes-128-cbc-sha (default) – Confidentiality cipher and mode for the DTLS Record protocol. rsa-with-aes-128-cbc-sha-256 – Confidentiality cipher and mode for the DTLS Record protocol with SHA-256 as the hash function. rsa-with-aes-256-cbc-sha – Confidentiality cipher and mode for the DTLS Record protocol with AES 256 encryption.   rsa-with-aes-256-cbc-sha-256* – Confidentiality cipher and mode for the DTLS Record protocol with AES 256 encryption and SHA-256 as the hash function. rsa-with-null-sha – The integrity cipher used for the DTLS Record protocol.  tls_ecdh_ecdsa_with_aes_256_cbc_sha384** – Confidentiality cipher and mode for DTLS Record with AES256 GCM and SHA384 as hash function. tls_ecdh_ecdsa_with_aes_256_gcm_sha384*** – Confidentiality cipher and mode for DTLS Record with AES256 CBC and SHA384 as hash function.  tls_ecdhe_rsa_with_aes_256_cbc_sha384* – Confidentiality cipher and mode for the DTLS Record protocol using ECDHE (Elliptic Curve Diffie-Hellman key Exchange). tls_ecdhe_rsa_with_aes_128_cbc_sha  – Confidentiality cipher and mode for the DTLS Record protocol using ECDHE (Elliptic Curve Diffie-Hellman key Exchange) with AES128 CBC and SHA as hash function. tls_ecdhe_rsa_with_aes_128_gcm_sha256 – Confidentiality cipher and mode for the DTLS Record protocol using ECDHE (Elliptic Curve Diffie-Hellman key Exchange) with AES128 GCM and SHA as the hash function. tls-ecdhe-rsa-with-aes-256-gcm-sha-384* – Confidentiality cipher and mode for the DTLS Record protocol using ECDHE (Elliptic Curve Diffie-Hellman key Exchange) with AES256 GCM and SHA384 as the hash function. tls_rsa_with_aes_128_gcm_sha256 – Confidentiality cipher and mode for the DTLS Record protocol with AES 128 GCM encryption and SHA-256 as the hash function. tls_rsa_with_aes_256_gcm_sha384 – Confidentiality cipher and mode for the DTLS Record protocol with AES 256 GCM encryption and SHA-384 as the hash function. * To use this cipher, DTLS version 1.2 must be enabled in the DTLS Profile. ** The SBC 11.1 and later versions do not support tls_ecdh_ecdsa_with_aes_256_cbc_sha384.
