SCTP Probes

The sctp probes are described in the following table:

Probes Description

state-change

Probe that fires when an SCTP session changes its SCTP state. Previous state is noted in the sctplsinfo_t * probe argument. The sctpinfo_t * and ipinfo_t * arguments are NULL.

send

Probe that fires whenever SCTP sends a segment (either control or data).

receive

Probe that fires whenever SCTP receives a segment (either control or data).

The send and receive probes trace packets on physical interfaces and also packets on loopback interfaces that are processed by the sctp provider.
