E

encapsulation

Ethernet

The technique used by layered protocols in which a layer adds header information to the protocol data unit (PDU) from the layer above.

One of the most common local area network (LAN) wiring schemes, Ethernet has a transmission rate of 10, 100, or 1000 Mbps.

H

host key

Combination of port bundle and SSG source IP address that uniquely identifies a subscriber.

I

Internet Protocol The network layer protocol for the Internet protocol suite.

(IP)

ISP	Internet service provider. A company that allows home and corporate users to connect to the Internet.

M

mini-ACL

Modular QoS Command-line interface

MQC

multicast

Access control list (ACL) with eight or less access control entries (ACEs). ACLs with more than eight entries are referred to as turbo ACLs.

See MQC.

Modular QoS Command-line interface. Also referred to as Modular CLI. A platform independent CLI for configuring QoS features on Cisco products.

Single packets copied by the network and sent to a specific subset of network addresses. These addresses are specified in the Destination Address Field.

O

OAP

Open Garden

Overlapping Address Pool. An IP address group that supports multiple IP address spaces and still allows for the verification of nonoverlapping IP address pools within a pool group.

Collection of websites or networks that users can access without having to provide authentication information.
