# Vsys Profile Configuration

A virtual system profile defines the resources for a particular service level. You can assign all virtual systems to the same profile or to different profiles to differentiate service levels.

You can configure 18 different profiles in addition to the root and default profiles (that always exist).

To create a vsys profile, enter the following information:

- Profile Name: Enter a meaningful name for the new profile. It can be up to 31 characters in length. Spaces are not allowed in the name. Hyphen ( - ) and underscore ( _ ) characters are permitted.

- CPU Weight: Enter a CPU weight. ScreenOS scales these weights relative to the weights of all vsys in the security device and assigns time quotas proportional to those weights. ScreenOS then enforces the time quotas over one second intervals. This means that as long as a vsys does not exceed its time quota over that one second period and the firewall is not too heavily loaded, no packets should be dropped. The range is 1 to 100; the default is 50.

For the following parameters, you can set a maximum value and a reserved value for this vsys profile. For session parameters, the maximum value is the upper limit that you do not want the vsys to exceed. For resource parameters, the read-write vsys administrator can only configure up the maximum number that you assign in the profile. The reserved value is the number that you want ScreenOS to guarantee to the vsys. You cannot configure a reserved value that exceeds the maximum value. The default reserved value for the parameters is zero (0) if you do not assign a numeric value, except where indicated in the parameter description.

- DIPs: D ynamic IP addresses.

Warning: Check with your administrator before you assign a DIP ID to a vsys. Duplicate IDs used on the same device can cause dropped or misrouted traffic. The device will not check for or prevent duplicate DIP IDs, nor will it send a notification if such duplicates exist.

- MIPs: Mapped IP addresses.

- MPolicies: Multicast policies.

- Policies: Security policies.

- Sessions: Number of sessions available for a vsys. It ranges from 100 to the security device total. If you do not configure a specific value in the profile, ScreenOS uses the security device total possible (no vsys limitation). ScreenOS drops excess packets to ensure that the vsys does not exceed the maximum value.

- User Service: User services.

- User Service Group: User service groups.

- Zone Address: Zone addresses.

- Zone Address Group: Zone address groups.

- Zones: Number of zones.
