Hi Lewis,
If you are talking about ASA, then below are the options about reloading a security context(not an actual reboot/reload though)
•
Clear the running configuration and then import the startup configuration.
This action clears most attributes associated with the context, such as connections and NAT tables.
•Remove the context from the system configuration.
For more details visit the link below and visit section:
Reloading a security context.
