A redundant central arbiter that provides traffic control and access fairness.
A nondisruptive restart of a single failing process on the same supervisor.
A service running on the Supervisor-2 module keeps track of the high availability policy of each
process and issues a restart when a process fails. The type of restart issued is based on the process's
capability:
Warm or stateful (state is preserved)
–
Cold or stateless (state is not preserved)
–
A nondisruptive switchover from the active Supervisor-2 to a redundant standby without loss of
traffic.
If the Supervisor-2 module has to be restarted, then the secondary Supervisor-2 (which is
continuously monitoring the primary) takes over. Once a switchover has occurred and the failed
Supervisor-2 has been replaced or restarted, operation does not switch back to the original primary
Supervisor-2, unless it is forced to switch back or another failure occurs.
