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.
