Creating the SCTP Configuration

Applies to: Tmedia 3.0, 3.2, 3.3

Stream Control Transmission Protocol (SCTP), a Transport Layer protocol, ensures a reliable in-sequence transport of messages.

To edit your SCTP configuration:

1- Select SCTP from the navigation panel

CreateSctp 0

2- Configure the SCTP service

• Make sure the box labeled Enabled is checked

• Enter a name for the SCTP service

• Select an appropriate service type:

  • RAW_IP

  • UDP

• Click Create

CreateSctp 1

3- Verify that the "Sctp Cfg was successfully created" message appears

CreateSctp 2
