The processes that can be restarted are:
• Management-related processes—TACACS+, RADIUS, CLI, SSH, Telnet, Console/Aux
• TACACS+/RADIUS—FTOS restarts the process and reapplies the TACACS+ portion of the
running configuration. You must enable process restart explicitly.
• Console/Aux—FTOS restarts the process; you must log in again after the restart. The threshold
for failover is 3 restarts per hour; the fourth restart triggers a failover. The restart configuration is
internal, and not user-configurable.
• Telnet/SSH—Each SSH and Telnet session is an individual process. If a Telnet or SSH software
exception occurs, only your session is cleared, and you must log in again; no other sessions are
affected. This behavior is an exception among the other restartable processes in that Telnet and
SSH are not literally restarted. Because of this, Telnet and SSH are not subject to the default or
configured restart limit; that is, the system never reloads due to a software exception in these
processes. However, a core dump is generated.
You can select which process may attempt to restart, and the number of consecutive restart attempts before
failover, but by default, every process causes a system reload or RPM failover.
