This read-only enumerated value reports the current run-time indicator state of the stack as a whole, distinct from any single member device's state. Admins check this to get an aggregate view of whether the entire stack is operating normally (rtinormal) or is degraded, since a stack-wide fault can differ from any one device's individual RTI. A stack reporting rtipending(112) tells the admin the stack is still converging after a topology change, such as a member joining or leaving, and traffic forwarding may not be fully stable yet.
