ACE
access control list (ACL)
Feature that filters incoming or outgoing traffic based on a set of rules that are applied to specified fields in the messages. You can configure an ACL on an incoming or outgoing interface. You can allow or deny traffic based on criteria such as the source and destination IP addresses and port numbers.
active/active
Redundancy configuration in which two units actively participate in the system during normal operation. If one unit fails, the workload of both units is processed by the remaining active unit. A load balancer may be used to facilitate active/active redundancy. See also load balancer.
active/standby
Redundancy configuration in which the primary unit actively participates in the system and the secondary unit remains in standby mode. If the primary unit fails, the secondary unit becomes active.
ad hoc meeting
A meeting that begins immediately (in contrast to a scheduled meeting, which starts at a future time).
admin context
On the ACE, you can define a single context or multiple contexts. By default, the ACE creates a single context named the admin context. Multiple contexts use virtualization to partition the ACE into multiple virtual devices. Each context can contain its own set of policies, interfaces, resources, and administrators.
