DESCRIPTION
"The state of this SCTP association.
As in TCP, deleteTCB(9) is the only value that may be set by a
management station. If any other value is received, then the
agent must return a wrongValue error.
If a management station sets this object to the value
deleteTCB(9), then this has the effect of deleting the TCB (as
defined in SCTP) of the corresponding association on the
managed node, resulting in immediate termination of the
association.
As an implementation-specific option, an ABORT chunk may be
sent from the managed node to the other SCTP endpoint as a
result of setting the deleteTCB(9) value. The ABORT chunk
implies an ungraceful association shutdown."
