The SCTP stream id (SID) is always set to zero on egress from the BIG-IP system. This causes applications that expect to send or receive data on other streams to fail.


Applications that require multiple streams will not function correctly. The SCTP protocol profile can be edited to set the maximum input and output streams to 1, which prevents a client from expecting to be able to use more than one stream. This might cause the client to fail to connect, rather than connect and get unexpected behavior.


The SCTP proxy always behaves this way when it receives a non-zero SID.



Fix Information

This release provides multi-streaming support for SCTP profiles when handling stream id values.
