Chapter 4 Configuring Security Contexts
Configuring Resource Management
B, and C are unable to reach their 3 percent combined limit. (See Figure 4-6 .) Setting unlimited access
is similar to oversubscribing the FWSM, except that you have less control over how much you
oversubscribe the system.
Figure 4-6 Unlimited Resources
Default Class
All contexts belong to the default class if they are not assigned to another class; you do not have to
actively assign a context to the default class.
If a context belongs to a class other than the default class, those class settings always override the default
class settings. However, if the other class has any settings that are not defined, then the member context
uses the default class for those limits. For example, if you create a class with a 2 percent limit for all
concurrent connections, but no other limits, then all other limits are inherited from the default class.
Conversely, if you create a class with a 2 percent limit for
all resources, the class uses no settings from
the default class.
By default, the default class provides unlimited access to resources for all contexts, except for the
following limits, which are by default set to the maximum allowed per context:
•
Telnet sessions—5 sessions.
• SSH sessions—5 sessions.
•
IPSec sessions—5 sessions.
• MAC addresses—65,535 entries.
