<ssl_tls_status> Number
• 0 (default value): disable the SSL/TLS on the socket.
• 1: enable the SSL/TLS on the socket; a USECMNG profile can be specified with the
<usecmng_profile_id> parameter.
<usecmng_profile_
id>
Number Defines the USECMNG profile which specifies the SSL/TLS properties to be used
for the SSL/TLS connection. The range goes from 0 to 4. If no profile is set a default
USECMNG profile is used (see USECMNG section).

18.5.3Defined values
Parameter Type Description
<socket> Number Socket identifier. The range goes from 0 to 6
<level> Number
• 0: IP protocol
<opt_name> for IP protocol level may be:
o 1: type of service (TOS)
<opt_val>: 8 bitmask that represents the flags of IP TOS. The range is 0-255
(the default value is 0). For more information see the RFC 791 [27]
o 2: time-to-live (TTL)
<opt_val>: unsigned 8 bit value representing the TTL. The range is 0-255 (the
default value is 255)
• 6: TCP protocol
<opt_name> for TCP protocol level may be:
o 1: no delay option; do not delay send to coalesce packets;
<opt_val>: numeric parameter, it enables/disables the "no delay" option
- 0 (default value): disabled
- 1: enabled
o 2: keepidle option: send keepidle probes when it is idle for <opt_val> milliseconds
