Vsys Limitations Overview
The global maximum value for any vsys resource is dependent on the security device. If you do not explicitly set maximum and reserved limits, the default values for the device are used.
When setting maximum and reserved limits for resources, keep the following in mind:
You cannot set the maximum value higher than the device-dependent global maximum value.
For all resources except sessions, you cannot set the maximum value lower than the resources currently being used (actual-use value).
You cannot set the reserved value higher than the configured maximum value.
The total allocated usage, which is the sum of reserved values or actual-use values (whichever is higher) for all virtual systems, cannot exceed the global maximum value.
