Chapter 6 Configuring Multiple Context Mode
Configuring Multiple Contexts
Detailed Steps
Step 1 If you are not already in the System configuration mode, in the Device List pane, double-click System
under the active device IP address.
Step 2 On the Context Management > Resource Class pane, click Add.
The Add Resource Class dialog box appears.
Step 3 In the Resource Class field, enter a class name up to 20 characters in length.
Step 4 In the Count Limited Resources area, set the concurrent limits for resources.
For resources that do not have a system limit, you cannot set the percentage; you can only set an absolute
value. If you do not set a limit, the limit is inherited from the default class. If the default class does not
set a limit, then the resource is unlimited, or the system limit if available.
You can set one or more of the following limits:
• Hosts—Sets the limit for concurrent hosts that can connect through the adaptive security appliance.
Select the check box to enable this limit. If you set the limit to 0, it is unlimited.
• Telnet—Sets the limit for concurrent Telnet sessions. Select the check box to enable this limit. You
can set the limit as a percentage by entering any integer greater than 1 and selecting Percent from
the list. You can assign more than 100 percent if you want to oversubscribe the device. Or you can
set the limit as an absolute value by entering an integer between 1 and 5 and selecting Absolute from
the list. The system has a maximum of 100 sessions divided between all contexts.

32 ASDM management sessions.
Note ASDM sessions use two HTTPS
connections: one for monitoring that
is always present, and one for making
configuration changes that is present
only when you make changes. For
example, the system limit of 32
ASDM sessions represents a limit of
64 HTTPS sessions.
